Hi all - this is my second grow. Previously did two plants in 5 gal DWC. That grow went really well. Battled some root rot early and recovered.
Current grow: 11 plants in a 20 gallon RDWC. Roots are healthy, lots of air stones and aerator nozzles. About 3 weeks into veg. About half of the plants are showing spots or something on their older, huge fan leaves. See pic. Not finding any bugs on my sticky pads.
Using floragrow 3 part nutrients. Ph around 6, adding hydro guard for root health and alight dose of calmag as my tap water seems to have enough calcium on the last grow. I did a 24 hour flush to make sure it wasn’t nutrient lockout. Not noticing a change. Ppm is about 800 when I change res water. It’s down to about 325 now as I add just plain, ph tap during top off.
Grow room is 4x8, two Mars Hydro TSW 2000w LED. Temp is around 70, probably RH of 45%
Any help appreciated. Topped the plants after 6 nodes, at the fourth node.
