Hello to all!!!! I am looking for some advice if anyone is willing to give their 2 cents. I have been growing for a year or so now, my first grow location is ending (flowering everything out) and my new operation is now up and running. With that said I am also changing growing methods. I was using FoxFarm (liquid & Solubles) in both soil and hydro. Ive had ups and downs and overall we have produced some great quality meds with mistakes and learning experiences along the way. Now, to get to my question. I have switched over to BIOCANNA, I am using that nute line with Cannazyme and Hi brix Molasses in Happy Frog soil. So I started to veg plants out at my new spot.....I started with 6 Super Lemon Hazes and i vegged them for about 6 weeks so i could cut them up and get mad clones before they went into flower. In their last week or so of veg i noticed some yellowing on the lower leafs. Now they are 7 days in flower and the yellowing has continuced and it seems to be moving up the plant. I have been feeding at the recomended amounts actually just under the rercomended amounts. Also, I have well water (Extremely Hard), the water goes through a salt softener then it is filter through a Small Boy water filter. At this point i think it might be an issue with the hardness of water or a deficiency of calcium or sulfur. I just flushed them today with straight water. Please let me know your thoughts!
just based on what you said and looking at the pictures it appears to be a Calcium deficiency....maybe try and add a little cal-mag or epsom salt to see if that helps clear things up...probably cant hurt
looks like there might be a little insect issue- but im not positive. looks like a few leaves been bitten.. the yellowing seems like a deficiency, what strength are the nutes? if its something low like 2-4-2, I would use more than recommended. if its high strength like 10-52-10, it probably isnt that. your soil's pH would affect that too, if your pH isnt right, then the soil doesnt retain the nutes correctly.. im not sure which nutes are best but most of them should be fine. goodluck bro
Thanks Fellas! I appreciate the comments. I will def try the CalMag or Epsom Salt. As for the NPK of BioCanna it is 2-2-5 for Flores and 3-1-5 for Vega, so i might try adding to my feed. No pests...if you're referencing the larger fan leaf it grew like that from my FIM cut. As for PH, from everything that ive been reading mentions that BIOcanna self regulates to a netrual level but this is my first cycle with this nutrient so will also get a soil ph reading. Thanks again for your thoughts!
Yeah, calcium defeciency. Could be ph related though. Well water is tough to deal with I've heard. I'd use distilled with cal/mag and see if that helps. I'm not familiar with your nutes, but you can safely water this way between feeding as well. Good luck
calcium deficiencies effect new growth, the new leaves are pale, and misshapen, or twisted. i would say its a pH imbalance, and is causing a lock out of a couple mobile nutrients. looks like Mg because of the spotting and some leaf tips curling up, and sulfur because of the yellowing veins, and leaves. epsion salt has magnesium, and sulfates in it u can treat with that... after u fix ur pH lock-out i know its a lock out because the plant is showing signs of a toxic salt build, the leaves that look like there wilting due to dehydration. whats ur pH at?
after your flush, if it doesnt get better flush again make sure you are using 2x the container amount of water. so a 3gal would need a minimum of 6gal of water to go through it. also stop giving it nutes untill you fix the problem. because if the nutes are the problem then continuing will only make it worse. good luck.
[quote name='janemba']calcium deficiencies effect new growth, the new leaves are pale, and misshapen, or twisted. i would say its a pH imbalance, and is causing a lock out of a couple mobile nutrients. thats weird i always thought the Calcium deficiency shows up in the older growth...i have never seen it effect new growth can you post a picture or help clear this up for us. thanks.. puffer
Thank you to all for the Advice! I did some testing and ill fill you in with what Ive found. The water that i am using is PPM-400, EC.9, PH7.2. After adding nutes (BIOCANNA) it is PPM-820, EC 1.7 and PH6.2 for my bloom feed. The run off is PPM 1980, EC4.1, PH 6. My soil is steady at 6.5 ph. So to combat the MG or Cal issue that i was having i added EJ- microblast (2 tsp/gal) and GO-CaMg (2 tsp/Gal). I feed them yesterday and im brew a tea to give them this weekend. I hope that this works. Thanks again for your thoughts!
Sounds pretty good man, but i would use distilled as the base and then add nutes and cal/mag. that way you know exactly whats going in. PPM of 400 in tap, which is what i understood, is pretty steep and contains lots of minerals and shit that could contribute to your lock out issues. Later.
Ive ran biocanna before now hydro so use there canna aqua. but it is awesome stuff. You should try and use there rhizo its a great root builder and protector. And there bioboost in flower is well worth the price. Know i used there whole line and it did awesome no deifciencys so its not the nutes. Its having your water ran thru a softner. you CANNOT use water ran thru a water softner. Canna suggests you use well or tap water for the extra calcium and mag it needs. and I did use cal mag the whole time but thats a lockout problem most likely either from the water softner or bad ph. You didnt mention ph. what is thta at? needs to be at 6.8 after you mix your nutes. You need to flush with a good ph'd water. double the amount of water as pot size. then run your nutes at 1/4 strength for a week to get her back going. ph the nute mix at 6.8. also mix some water at 7.0 run thru till you can get drainage and ph test that also. you might need to adjust that 6.8 number depending on how out of wack the soil ph is. hope this helps.
I do think that the water is what is creating my issues. I have well water that is softened. So I am trying to decide weather to add more filters after the softener or teeing my water line before the softener and taking it straight to the grow room. As for my PH, when i mix my nutes (Bloom) my numbers are - PPM 820 EC 1.7 CF 17 PH 6.4....Runoff is PPM 1980 ED 6.2 CF 40 PH 6.3-6.5. The HIGH ec could also be causing problem allocating mobile nutes. I feed the bloom last with a tea...just bubble my canna and hit them hard with MICROBlast and CAMG. Whats ur thoughts. Would you continue forward or consider flushing? Also, are these affected leaves going to recover or are they a lost cause? Thanks again GC!
IDK man. I would VERY suspicious about the water causing your problems. JMO. i think, if you are continuing to see problems, i would go ahead and flush with 3x pot size and use Distilled water for the last couple gallons (all if possible) with a touch of cal/mag, ph corrected to 6.8, if needed. If using well water (which usually has enough minerals) your cal defeciency is likely from lockout (not deficiency) of some sort. Yes, the high ec could be causing problems, but since ph is ok it shouldn't be too much of an issue. And yes, the affected leaves are goners. Edit: I read this wrong. I though you were saying the water wasn't an issue. Sorry, I really can't help with the well water issue. Is going with distilled + calmag for watering an option? If so, that's what I'd do. Good luck.
Thanks eddro! Watering with distilled is an option right now because i only have a few plants. But that will not be the case soon as my veg room continues to grow. I am a caregiver and i can have 72 plants. 32 in a perpetual rotation in the flower room and the remainder in veg. So for now it would be too big of an issue but in a few weeks id be looking at a couple hundred dollars a month in water costs. I plan on having a plumber friend come over this week and give me options for my plumbing...ie-reverse osmosis system after the salt softener or teeing off the line and running water (Not Softened) to the grow room. In my two feedings with mircoblast and camg i have noticed that the spreading has slowed down so i think that i will continue to feed and if i notice more yellowing then i will flush. thanks again!
if your going to be growing that much produce I'd get a few 55 gallon water barrels, stick em up on a shelf and have a RO filter constantly filling em.. Wait, that is what I do.. cheap high-quality h2o always available. I paid $15 for used barrel, $20 bulkhead & spigot, $20 for ice maker hookup kit, $65 for 100gpd filter... Even if you got distilled for $0.50/gallon (I'd pay $0.80/g here) this would pay for its self within 4 tank fillings not to mention you wont have to lift any of it. if your ppm starts off that high it makes it difficult for your plants to get to the good stuff your adding.. they can only eat so much and alot of what your giving them they dont want.
Oh wow, I didn't realize you had such a big grow going. If you can get a R/O hooked up to your system that would be great. I have no idea about the softened water. If you have a journal post up a link? Good luck.
Ben, Love the set up! working well in a confined space. I think i might do something like that.. the only concern that i have is that my grow in the second floor...just that much water (55 drum) if something bad happend would be horrible. so im not sure about the drum yet. but when i was messing around in my basement i noticed that i have a culligan RO system that is just sitting there mounted but not hooked up. So i might just take that straight up to my room and have my small boy filter to the RO. EDDRO - No journal yet. though i do have pics of the construction and build. I will be putting a journal together once i have some of these headaches solved. So with that said, I feed the ladies again today with Distilled ( Ben I got them for 73cents) Biocanna line, CaMG, Microblast and hi brix molasses.... The distilled water readings were PPM-10 EC-0 CF-0 PH-8.9....So i added my nutes... water then read...PPM-790 Ec-1.6 CF-16 and PH 4.5....i was shocked that the ph was so low...with my house water my nutes readings never get below a ph of 6. so i fed anyway... and i noticed that my runoff water was very low in PH.... not plant was above a 6.5....they were all high 5 and low 6. Whats ur thoughts? Keep feeding? flush? Thanks for the advice and support!
let the nutes sit for a while, some of them right after mixing take a dive towards acidic when in clean water (little buffers in the water) and after sitting and reacting (creating buffers) come back neutral. If after a few hours your nutes are still that acidic add something to bring the ph back up.. either ph up concentrate, baking soda, etc. I wouldn't pour anything less than 5.5 over your plants unless your soil was giving you very very high ph readings. Bring it back up to 6-6.5 that way your soil pH remains stable. If your flushing dont add any nutes, take the dilstilled water down to ph 7 and just keep saturating the soil, you dont over-water in one watering.. most people say 3x your potter size.. so a 3 gallon pot your gona wanna pour 9 gallons of low ppm and neutral ph water into your planter and out your runoff holes... when your'e done check the runoff pH, should be between 6.5-7.. if not keep flushing. after the flush let your potter dry out completely and start back up on your regular feeding schedule, if you keep the pH of everything going into your soil roughly the same and your water is mostly nutrients and not hard metals then it shouldn't have anymore lockout issues.
