Hi there, I'm 7 weeks into flowering and I've just noticed yellow curled up leaves on my 4 plants.
I'm growing in a DWC system called nutriculre bubblebox,600w light in a growtent. My humidity is between 50-62% , water high 60'sc and air temp 58 - 72 c.
I change my water and nutes fortnightly and this lot of water has been in there for a week already.
Yesterday eve I had no problems but this eve this appeared on all the plants.
Ps ...the plants very in height but the closest is 14" from light with a fan just below the light. Even the smallest plant is affected with yellow leaves so am I correct in ruling heat burn from light out ??
I'm really worried as I'm only a week out from flushing !!
