It's in a 5gallon dwc it's in late bud been feeding straight rain water un-ph,ed for two weeks. Under 400 MH. Temps are always under 85°. I have let the nutes get very low I couple times though.RH is at 50%
Looks like fox tailing to me, may be wrong but high temps and light too close comes to mind... How far away from top is your lights, stress can make them do this due to heat ?
The two main colas are about 2 or 3 inches from light but they are fine,its most of the smaller buds that look this way. The heat never gets above 85°.
