Hi I need help all my plants looks really bad anyone can tell me whats going on couse I dont have idea
Temp 25
Rh 55%
And I follow AN feeding chart
PH 6. 5
EC 1,8
EC 1.8 is quite high IMO. Maybe a K excess would be my guess. I would try backing way off on the nutrients for a week or so. Then slowly pick it back up until you are ready to flush for harvest.
All in all...they don't look too bad!
It's Looking livke you are overfeeding them!
This are signs of Excess!
Look on the Leavetips ect. ect.
An it's not the end of the grow for All plants like @MindFlowers68 commented.
They don't look that bad honestly. You are getting towards the end of the grow.The plant is starting to change color naturally. I had a similar leaf tip curl up. I think I underwatered along with heat stress. mine looked worse. but looks like your temps and humidity are near perfect. ec is good. So I'm assuming it's from the roots drying out.
