Where am i going wrong?

Usually curling upward lave is heat stress u knowur temp in there nrotha

i would say more then just heat stress plant in your pic does not look healthy at all, are you giving it enough nutes?

yeah, it looks like a combination of issues. remember that once a leaf shows issues it will stay that way

36Chamberz: a picture may be worth a thousand words but you haven't really told us enough to give us an idea of what's wrong. Plants need: air, light, water and nutes. If you're growing in hydro root and ambient temperature are a lot more important so it would be helpful to know:
1. What are the nutes you're using and the relative ppm's you're trying to maintain?
2. The pH of the mix. Is it steady or does it swing?
3. What kind of water you're using: bottled, R/O'd, tap, well, etc.,?
4. What kind of lighting you're using and how close is it?
5. It would be helpful to know the ambient grow room temperature and the reservoir temperature?
6. What kind of ventilation are you using. Summer in some parts of the world gets pretty hot and if you're growing in a closet you can suffocate them.
7. Is there any indication of algae?
8. Are you keeping your reservoir clean?
9. Have you check with: Cervantes, Rosenthal or Green? All three have good trouble shooting sections in the back of their texts. These forums are great but when you have a problem it can be difficult getting the answers in a timely manner. I hope that helps. HSA

Hey guys. It's not a culture problem meaning I keep everything clean and my nutes and res get changed regularly. I keep a close eye on ph and everything else so even though it fluctuated occasionally that's not it either although I was slacking on my duties for a time so superstoner might be onto something there. I'll keep an eye on new growth. It is also getting real hot where I am and the room is occasionally pushing the very low 80s like 81 or 82. I'm using 5gal buckets on a cement basement floor but I'm not sure of the temp in each bucket. I use strait tap water and I've been using foxfarmnutes for a really long time. I'm starting to think it's just too hot sometimes and I need ac. Would love to hear your thoughts and suggestions. Thanks everyone for the help.

drop a frozen water bottle in the res a couple times a day and think about adding a good beneficial.
