Heat stress? Light stress? Nute burn?

Spliffliciousstarted grow question 6y ago

Hi y’all Since my girl started to flower the top leaves near bud sites have this weird cupping downwards look. I doubt it might be a nute burn since I already gave her a good flush. I think the heat might be the main issue (86-87degrees during day). What do u think? Day38autoflwr

Hey, buddy! 👋 Don't worry, your plant is just showing you that it's really hot! 👆 There's a wild heatwave going on all over the world! So you're not alone with this problem! The weather forecasters made an inaccurate prediction, but they promised it would last a week! You also have a slight deficiency from your recent flush, but it's not critical or significant! So don't stress, be patient, forecasters can be wrong in their predictions, as they often are! 👆 Good luck, buddy! ✊😇

Switching to flower nutes also demands to start your girls at a lower ppm than in veg. You then increase as you see deficiencies. Feeding at the same ppm as in veg will bring you problems, guaranteed. Cheers

Make sure your letting your girls dry out between waterings, looks like early sign of a little overwatering to me. Cheers

Basically the top leaves have this razor-sharp edge look, it doesn’t seem normal to me. Can it also be light stress? As far as I ve google it could only be nute burn, heat stress, light stress or humidity stress. RH is 50-55% so that shouldn’t be a problem. Nute burn? Already flushed her with 20L 6.2ph Kanger Water and added some nutes at the final 1.5L of water. Light stress? Would make no sense since she has been perfectly happy in her veg. The problem occured when she switched to flowering, a couple of days after. Heat has been a pain in the ass since the beginning. But I guess it would make sense why it didn t show any stress in seedling/veg stage since they can standnto heat better than flowering. I already ordered a portable AC machine to get degrees down, should arrive by tomorrow and see if that makes any difference. I’m almost certain this will blow off my electric bill.. :< What do you guys think? Heat stress or smth else ? Peace ✌️🏼
