I have done some research as to what is affecting my plants. It looks like a boron deficiency and a calcium deficiency. Maybe phosphorus, but probably PH and temp fluxes. It doesn't seem debilitating, but I am curious as to what it is because it seems to be getting worse. Thanks for the input! -Dr. Rosko My outdoor was so much better. I am so disappointed in myself with these type of issues.
You need to read through the pinned threads...then fill out the form in the "when posting sick plants...." thread here. Its kinda hard to help you without any info.
We need all the info on your grow including: What type of medium; soil or hydro? What brand and type of soil? Indoors or outdoors? What strain? How old are the plants? What type of lights and how many watts? How far from the lights? What is your watering frequency and source of water? What, how much and when was it fed? NPK? What is the medium/runoff pH and PPM if in hydro? What are the temps and humidity in the room? What size pots? Any bugs? Look real close. Any other pertinent info? If any of these questions have already been answered please disregard as I cut and paste this for everyone. If there is leaf discoloration please TAKE PICTURES WITH ALL GROW LIGHTS OFF, ESPECIALLY HPS & LED's. Taking pictures and taking them with lights off, allows us to see what the leaf discoloration looks like. Sent from my NSA recording device.
Thank you Blackmore for confirming my suspicions. For the rest of you all here is some more info though I do not think it is relevant. I only wanted people to give opinions on the pictures. soil with hydrotonn on top as a mulch. It is a blend of many soils with a layer of bat guano, earthwork castings, and some blood meal on the bottom layer. It's not a thick layer, but I may have overdone it. (I think they hit this layer too soon) Soils are a mix of fox farm ocean forest shit, some roots organics, some soilless mix from my place of work (peat and perlite basically), some eggshells sprinkled in and I think that's it. Its in a layers. Top is inert stuff, under the root ball was the soil mix, and at the bottom inert stuff with the bat guano, EC, and BloodM. Indoors or outdoors? Indoor What strain? White widow, Granddaddy Purp, and one Durban poison plant. The white widow seems to be prone to calcium spotting since I started to grow it's mother plant outdoors 7 months ago. Durban has the brown boron deficiency looking spots, and the GDPs are healthy and probably not pictured. How old are the plants? 7 months total, about one since rooting. What type of lights and how many watts? MH, 600w How far from the lights? It varies, usually 15 inches from the plants directly under it What is your watering frequency and source of water? I use an RO filter with some General Organics Cal/mag added. I won't buy that stuff again though. Smells like vinegar and fucks with the PH. Any recommendations for better Ca and Mg plant sups would be nice! Sometimes I use Tap water which is on a well with a decent PH and good sulphur content. It never hurt the outdoor girls that were beastly and perfect most of the time. I water when the plants start to dry. And I have already done a flush. What, how much and when was it fed? NPK? Unknown because of the soil content. There is probably an excess of nitrogen and a lack of phosphorus. Some age old grow at a low concentration has been administered lately. That stuff is my favorite and worked wonders on the outdoor mothers. What are the temps and humidity in the room? Temps fluctuate between 75 degrees F in the shade by the light to 65 at night. What size pots? 1 gal Any bugs? Look real close. No bugs though I think there are a couple fungal gnats and I may have seen a thrip in my herb planter in the kitchen. My work at a greenhouse plant farm has me paranoid about bugs for sure. I come into contact with all sorts of shit. I was just hoping I didn't bring a plant disease home. Any other pertinent info? Not Really! Thanks for the consideration. This is my first post. I finally broke down and became a member so I could talk to everyone directly about problems like this. Kind Regards, Dr.Rosko
Spend some time in the organics section...they can help you build a proper soil. Your method doesn't sound like anything I've read, but ask those who have been doing this for years.
Dr. Rosko, what is your RH and temp? I think you are suffering from low rh. Or a VPD (vapor pressure deficit). Really, RH has little to do with the all important VPD, which is what we should pay attention to with plants. You are suffering from some mineral deficiencies due to the high salt content in the tissue causing lockouts of other minerals. The high VPD is causing your plants to drink up more water which comes with the nutes and salts and is causing the lockouts or deficiencies. With the soil and content within the soil you described I would suspect all of the needed minerals to be there for the plants.
You are right pirate. I winged a recipe/idea with what I had. I think my only issue was using 1gal pots because my two "smartpots" cloth pots are doing fine. I think the plants didn't have time to develop before hitting the layers. Besides that I think my only issue was not adding enough phosphorus in some form. It should be fixed in a week. I'll add P next morning in the form of Age Old bloom, my favorite. Pics to follow...
Bizie, I thought this might be an issue! My rH is 71% right now, it has weirdly rectified itself. But i think my gauge is wrong or something because the air in the room is 56% my tent is at 71% supposedly but that doesn't make sense. It has bee in the upper 40s most of the time because of a dehumidifier I have running elsewhere. I shut it off the other day to get the rH to 60% Dr. Rosko, what is your RH and temp?
