My first grow, I had the same problem. Grew four strains, one being White Widow. Got a few weeks into bloom, one day after I watered and nuted, most of the top leaves looked pretty much like yours. Like a claw but pointing upwards, with brown and burned spotting.

My advice is to flush the affected plant(s). There is a sticky covering flushing here.

If the other ladies are happy with their food, then keep feeding them at the current rate. Then just dilute that food with pH'd water for the querky querkle. :stoned:

You didn't say what kind of Fox Farm soil you were growing in. If it is the Ocean Forest (?) stuff, I hear it is very hot so beware.

Why did you change your pH to 6.0 this watering? You should be around 6.5 - 6.7. I don't think this is your main issue but it may be secondary to the overnuting.

Good luck. :thumbsup:
crabbyback Reviewed by crabbyback on . Please help, brown spots and curling leaves I'm not sure when this started but I know it has gotten worse since I watered last about 3 days ago. I made the mistake of trying to grow multiple strains in the same room with the same formula. It seems that only one of the strains is effected. The effected strain is querkle (purple erkle x space queen). Unfortunatly, I trimmed away all the worst leaves before I took these pictures. Hopefully you can still get a good idea of what's going on. The room is way overcrowed as it is and even Rating: 5
