Fronti89started grow question 3y ago
Can someone tell me what's wrong with the plants? Unfortunately, the plants aren't with me, and my friend turned off the ventilation, and that's when the trouble started. I had a temperature of 33°C and humidity of 90% for a day. Luckily, I noticed it after one day.

I just done something similar last week and a few of my leaves went like that, mine was on the older growth with the new growth not showing the same problem. Once I turned my extractor back on it didn't get any worse so i put mine down as environmental problem. But like Roberts has said I'd check your ph runoff just incase it's something out of balance in your growing medium.

In one way it looks like phosphorus, but in another it looks like magnesium. What is run off ph? I am thinking they got too dry, and the ph shifted on you in your substrate. Causing a lock out. Hard to say for sure with limited information.

Was ist los ? Magnesium mangel oder Stickstoff..HilfeHey guys,
I don't know what's going on. My ladies seem kind of sad. They were repotted 14 days ago and have now received fertilizer twice. Before that, they had pH adjusted water for 10 days. The fertilizer is Canna Terra, and I'm giving 3 ml per liter of water plus CalMag.

What to do with crispy curly fan leaves that do have some resin on them?, I'm already on flushing.Some fan leaves are starting to look a bit too crispy and curly, they do have some trichomes, I'm 3-4 days into flushing.
I'm not sure if the dry matter can "contaminate" the buds somehow, and don't know if I should do something about it, I'm planning to get some "bubble hash"

Hail damageAfter a strong hailstorm, my automatics were defoliated by 30-40% and the bed was flooded (50l box with holes in the bottom). After that, the flowering growth stopped and the leaves first turned brown and dry at the tips, then completely. What is this?
