Kind of looks like it could be both light stress and calcium issue.

Guys been going great until I checked today. My top leaves turning grey white and crunchy on 2 plants. 3rd plant ok. What do you think too much Kool Bloom? To much heat from the light?? I don’t think it’s the latter I decided to flush for 2 days to clean it out??

Tips curling up I noticed the tips beginning to curl up. I did gave her bio grow in the last two weeks 0.5ml/lt ph 6.5 almost every watering i used bio grow. I have another 8 plants of different breeds and none of them showing anything wrong. I wander if its the nutrients or perhaps the light?

Looks like light stress I assume with the canoe and curl. Moved light from 100% to 75% Stil at 35in from canopy. Should that do the trick? Also should I have already had it at 75% and moved it to 100% during flower? Or how do you guys do your light power

Yellowing, curling tips?I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistake

Light Stress Had to move my plants to a new space and under a better light, can see taco type appearance to leaves, I'm assuming this is due to light stress? I've lowered the plants and also turned the light down a little until I know what is going on.

Starting Training I'm currently worried about my older plant set that seem to be constantly having the leaf edges curl and seem to be a little droopy and a little too dark green. Also I feel like I should be doing some sort of training. I would love to have some feedback on what you all think. ✌️

Upward curling leaves Yesterday applied heating mat bcs temp was dropping to 14C nights. Now it stays 30C allday with RH 30%. I have found my seedlings looking like this morning. Leaves look dry. Could this be the excessive heat shock? Or soil dried up quick? What should I do? Water? Raise RH? How?

Week 4 Seedling is wilting/curling! (See Pics) Hard and dark cripsy edges on all growth. I dropped two fan leaves incase it was mold. Looks a tiny bit better the next day after taking off the humidity dome that was on for about 24 hours before noticing the curl.

Why are some leaves curling strangely?Hello everyone, the problems begin unfortunately. Why are some leaves curling strangely? I have not given any nourishment, the temperature and humidity are constant, will it be a problem of PH or EC? Thank you in advance.

I'm having some sort of mold issue I think. I cant figure it out I havent seen anything that looked like this. I've Googled leaf symptoms and molds but nothing looks similar enough for me to say that's it for sure. Any help will be greatly appreciated!
