I don't know what hydro 3-1 is so can't comment on your nutes.....but your ph is too high....for hydro it should be lower....between 5.6-6.2. I would also lose the MV lighting...inefficient and hot.
Weedhound Reviewed by Weedhound on . Yellow Brown spots on leaves, leaves curl inward, hydro setup My second grow with the same setup. First grow went fine, but this time I'm growing 6 plants instead of 4. My question is, am I over feeding or underfeeding? I give the hydro setup a quarter cap of 7% nutes every couple weeks. I change the water completely at the same time. The leaves have small yellow spots that turn brown and then the leave curls inward\upward like a claw. Any ideas? -indoor -hydroponic -Hydro system type (Wick\ebb n flow) -Nutrients - Hydro 3 in 1 (the classic 7% Rating: 5
