It stays at 80 degrees and I have a 400cfm extraction fan and also a online booster coming straight from the AC. I REALLY appreciate the feedback. I think it's a deficiency of some sort and have done a lot of research but cant really find anything that looks like this. There is no pests and I am using all organic products mainly go box with fox farms ocean Forrest soil. Supplemented with azomite and dolomite lime. I will post more pictures In about 30 mins

These are two different plants and two different strains both now showing like red purple tinge on the leaves. I know it's normal to lose leaves during flower but I have lost about 70 percent of all the big fan leaves by those weird colors I showed them turning yellow then rolling up at the leave tip and becoming crispy then falling off. I water with r/o water every time and go like theirs water-feed-water-feed etc.. Using General organics go boximage.jpeg image.jpeg image.jpeg image.jpeg image.jpeg image.jpeg image.jpeg image.jpeg image.jpeg

I looked at every resource I have I cant find it either only suggestion I can give is try flushing a few times get rid of whatever may be causing problems and then start your nute regimen again I grow hydro so soil isn't really my thing sorry wish I could help more. Let me know if you find the problem. Hopefully flushing should help use RO if possible ph around 6.5. Good luck

Have you looked at Molybdenum deficiency it might be your problem after looking again it looks close the lower your ph is the more susceptible to Molybdenum deficiency important to keep it closer to 6.5 in soil I know I'm repeating myself I also copied your pics and sent them to an expert grower I know hopefully he will know exactly what problem is. Good luck

Thank you and I actually did look into that and I have some of the symptoms but not all. If I had to guess I would think it was that tho. so I think I am just going to flush and hope for the best. Thanks again for your help tho dude

As far as LST goes I usually wait till stems are about 8-10" long and start tying them down usually about a month and a half depending on strain. The idea is to make all the colas the same hieght that way they get the most light. Do you also top a couple times or fim there are different views to this but whatever works best for you is really all that counts. And yes I think 85° is too hot i try to keep my grow room at 77-78° max you should also try to raise humidity for now closer to 55-60% during veg 40-50% during flower less toward the end of flowering. Good luck check out I love growing marijuana for some great info from Robert Bergmans a world class grower and teacher. You can get his grow bible and plant care ebooks free on his site. I'm actually a student of his. Learning to be an expert in the future of growing

Awesome thank you very much Squirt. I'm probably going to start LST ing today. I've never topped or fimmed as I don't want to fuck anything up. I haven't even cut the dead leaves off my plant. I just wait for them to get crinkly and crispy and fall off on their own. Humidity is more my problem right now. It stays at 25-30% unless I put a pot of water in there. Then it raises to 55-60%. I got the temp situation down and have been at 74-77° during lights on and 66-73° at lights off.
I'm going to check out Robert Bergman's I love growing Marijuana today as that sounds like a bunch of information can be used and found from there. That is bad ass that you are a student of his. I would love to get back into school and learn more about plants haha. Once again thank you for all the advice.

Yup! its not a N deficiency, although upping it wont hurt. try finding some stuff with more trace elements.

Its only normal to lose leaves during flower on these forums. There is nothing natural about it. Most often caused by high P and low N so called bloom foods. A healthy, happy plant being fed a proper diet will remain green all the way to harvest. And the plant in the pics at the top of this page looks to be N deficient for sure. The source leaves being the first to show top to bottom.

It ended up being spider mites and I knew it was anything but normal but I managed to salvage it and make best of it. Two were clones(ones in pictures) and those were the two hit super hard and I suspect I bought them already infested bc no matter what I tried or what I did it just lost leaves and wouldn't grow "normal". I appreciate everyone's help here and without it I don't think I would have made it to flower.
