Hey guys, got a couple of Kerala Krush....They are a 100% sativa... I vegged them for a month at 18-6, and they have been in 12-12 for about two weeks now.... Soil mix is promix hp, wc, pelletized lime, and perlite... I have feed them jacks all purpose 20-20-20 like two or times now....Each time i did i waited and did a regular water in between....I also water the day before to make sure the roots are moist...The last time I fed them the Jack's they exploded in growth.... I also have Jacks Blossom Booster 10-30-20 that I plan on using soon..... The leaves on the plant in general are not that green and really have not been since I started growing it...However, it seems the lighter colored yellow leaves are starting to creep up from the bottom to the midway point of the plant...Also seems to be the larger fan leaves that it is happening to more.... Are they starving ? should I start with the blossom booster ? Or is there something else I should be giving them ? also some of the bottom leaves of the plant have turned a crispy brown, and some are falling off.... If you see any of the real light brown spots on the leaves that is from a foiler feeding I did with an organic tea mix that I got from the local hydro guy.
fan leaf death is normal in most grows that leave them on for flowering...she's just sucking in all the good stuff she can to feed the flowers to be as big and healthy as possible.
i completely agree but in this case, he is very early in flowering. i'm guessing there is some sort of deficiency or another underlying issue ensure runoff is balanced and feed with 1/2 strength bloom nutes. then water, water, feed
I don't have a tester...any recommendations ? Should I just go to local hydro store? what should I expect to pay for one ? thanks TheAnswer121, that's what I am thinking that it is too early for them to be falling off...I have kind of noticed this yellow/lighter colored leaves for at least a few weeks now....I am planning to transplant them from the 1 gallons they are in now to their final pots which will be 5 gallon. I'm not sure but from google searching images the pics of other Kerala Krush seem to be more greener than mine...Over all the leaves are not that green...It's hard to see from the pics though.
If you added lime in your soil, your pH is buffered. You shouldn't need a meter. Looks like a nitrogen deficiency, but your fert shouldn't be locked out... Odd
I'm having the same issue but it doesn't seem to be slowing bud growth so I honestly just pick off whatever I see. And it's only on the fan leaves for me too. I'm going on week 6 of flower. My suggestion would be to just pluck them off. I read about this on GC earlier today and they mentioned a few different things which one you might actually be victim of and that's being root bound. Could also be some sort of Mag lockout as well. A number of different things. My advice to you would be keep doing what you are doing and just weed out all the bad leaves. Once you see growth starting to decline and halt then you need to worry http://forum.grasscity.com/index.php?/topic/1276885-My-First-Grow-Kerala-x-Skunk-#1-&-2x-RQS-Critical
Your plants look overwatered from the droopy leaves. Your fertilizer has plenty of nutrients to provide good growth. You have a nutrient lockout from anerobic conditions in the potting media. PW
I pretty much waited until the medium is bone dry before watering again, so I don't think I am over-watering...But thanks anyways. Also, soil gets a lot of air as I use Air-pots.
Bone dry medium is death for the microherd in organic soil. They come back when you water, but there's really no benefit at that point. Keeping the soil moist keeps the herd making nutrients.
I do think they look overwatered, but if you say the soil is bone dry, that must not be it. Otherwise I'd agree on nitrogen def.
I wait just about until they are bone dry usually, and then water.....I will water untill run-off is usually about 1/2" deep in drain saucer..... Air-pots are roughly 1 gallon, and I usually use around 1/2 gallon maybe a little more to water 2 of them. I'm beginning to think they might need more nutes.... The first time I nuted I used the lowest dosage of jack's....I fed that once or twice.....last time I upped it to the next dosage.....like I said plant exploded after I fed them that......that's why I'm thinkin maybe these plants need more nutes.... So if they do need more nitrogen I'm assuming it would be smarter to go with jack's all purpose 20-20-20 rather than the blossom booster which is 10-30-20 ?
well here's some updated pics...a day and a half later and those yellow leaves on the one plant are just about toast....I was bust with work, and once again the soil was bone dry....I am going to try and keep on top of the watering better...I am going to nute them in about 13 hours from now when they are waking up...Also, going to up the dose on the two Kerala Krush. edit: pics are in next post
from the looks of the pot leaves chart it looks like it could be either nitrogen, sulfur, or zinc deficiency.... Anyone got any ideas ? thanks SC
i am growing a thai 100% sativa right now and i am in flowering too at about 6 weeks of 12/12 lighting. i have read some sativas are nitrogen hogs. my bloom nutes have a bit of nitrogen in them. i use gobox, and some supplements(used open sesame, beastie bloomz and now cha ching as well as snow storm ultra). one of my plants is behaving oddly and i am not sure why so i am no answer man but i'd try giving them some more nitrogen like others have said. just re-read your post. if you have pelletized lime in your soil, you should be good on nitrogen. maybe it is nute lockout from ph. probably high since lime is a base. i use ph paper because i don't want to have to deal with calibrating anything every time i water. i got the paper from amazon but you might be able to find it at a pet store(aquariums) or garden shop. my hydro store only has the 0-13 paper. i use 5.5-8 paper from hydrion. it is like $5 and lasts for a whole grow...
I use tap water here from the city.... I talked to the local hydro guy before I started my grow, and I think his words were something like : "we have the perfect tap water for growing plants".....I do know the subject of ph was brought up, and he basically said it was perfect or something.
local hydro guy seemed to think it could be nute burn since it's mainly only the older and bigger leaves that are burning... \\Well I nuted yesterday before I talked to him so we'll see what happens...I'll check on them later tonight.
Nute burn would affect all the leaves. Specifically, the tips. I see it all the time when I feed boosters in flower.
update: seems to be getting worse....I am now seeing that some of the smaller green fan leaves seems to be shrinking and shriveling up while staying green....I nuted them about a day and a half ago...I upped the dosage a little...Really haven't seen that explosive growth like I saw last time I nuted them.....I am wondering if maybe they need bigger pots to grow larger...they are on one gallon now...I just prepped the soil earlier today for the new 5 gallon pots they will be going into....But don't think that is the reason for the yellowing, browning, and withering of leaves... more pics:
