Grow Mediums 400w LED DWC Auto Blue Mystic Hydro Grow

[Hydrogrow]

Day 17. 400w LED (not sure what brand, came from China.) free shipping took 7 days, 200$. I had MH/hps 400w but the electric bill was crazy high in the summer so I decided to make a change. I didn't think I was gonna be impressed by the led but I am. It doesn't have the intensity like the hps but it holds its own. I'm using GH Flora series with rapid root starter. DWC with 5 gallon buckets. 1 fan blowing on plants, exhaust fan. Temp is 78F H is 48%. Using 3.75 net cups, rock wool, hydrotone. Growing 5 Auto Blue Mystic. Everything is looking fine except for a couple plants leaves are curling. Ph fine, temp is fine, not sure what the temp of the water is but it's not warm. I have the light about 12 inches from plants. I don't feel any heat when I place my hand on top of plants. On my 2nd feeding I went from 1/4 to 1/2 strength nutes but I don't think that is causing it either.... I'm not sure what's causing it. I think it's the light but I don't know.

He bud,I'd suggest raising your light up a bit,usually between 16-24 inch in veg to allow good node spacing and so the young uns don't get blasted by the intense light.if they start to stretch to much just lower it :tiphat: im not familiar with dwc but have a read through some dwc grows in the hydro section to see if you need to maintain a certain water temp range :smokebuds:

They look fine that little bit of curl seems to be normal.

Thanks everyone. I moved the light to 16 inches to see if its that. I won't stress about it.

Day 29. Looking good. 2 or 3 of them smell good. One smells very sweet but over all they don't have an over powering smell like every other weed plant, very manageable.
