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?
