I'm not sure what is going here, i do not beleive its overfeeding or heat stress, im more inclined to think it's a humidity issue as my humidity does not go above 30% (waiting on a humidifier) would low humidity levels cause leaf tips to curl down?
Running a 400w HPS i beleive i noticed this...
This is what the plant looked like when i noticed a spider mite.
Decided to ask a friend for some advice and they gave me this.
3 hours after lights came on i noticed the plant looking like this.
2 other plants sprayed. 1 showing the same condition only minor other showing 0 symptons.
