Hey guys/gals just wanted to get your opinion... I'm using R/O water, ph is 6.6 - 6.8, with organic nutes (Fish/kelp/bone). Been veggin 7 weeks. My thoughts:
Bonemeal is slow release so they are suffering a phosphorus diff???
Root Bound? Going to re-pot soon.

I've been going with Fish emulsion (5-1-1) and kelp (.1-0-1) double dose. So (5.2-1-3) I was thinking Phos also so I topped dressed with bone meal (0-5-0). Maybe it's to slow acting. Not sure? Suggestions for Phos. source?

Keep ph right where it is and get some nitrogen and phoporus for next watering try to go at least 10 or better 10-10-10 ect and give her a few days damaged leaves won't recover hope this helps gotta run...it's easy to under feed when your using organics just my exp :weed:

my pages update so slow sorry I'd make a tea with the bone meal it's sooo slow any chance you have a fire pit around? hardwood ash is the best supliment I know of it's fast absorbing not real harsh it dose tend to raise your PH so whtch it close if you go that route I use Alaska Moorblom it's 0-10-10 in a pinch its organic but on the salty side and very acidic but fast acting watch the PH and don't use to much..... I Like woodash:)

Jolly G, it is most likely a phos deficiency.
I always see this with soil growers that run a higher PH. Phos is not able to be taken in by the plant above 6.5, so drop your PH to 6.0-6.5, don't add more phos yet. It's there it's just not being taken up... GoodLuck JG

This guy has more expertise in this area, so he may know more than me as I grow Hydro...
Phos is most soluble under 6.5, but after further review is still semi soluble up to just above 7, so adding more or lowering PH slightly will both help. Lowering the PH may screw with other Nute intake so I would have to say listen to Ntmine!
