thanks
@Waira
the poo machines are comets and goldfish with a few algae eaters to keep things clean,
the curled leaves could be to much nitrate, sitting on 120ppm. Or as it looks, N tox
my nute addiitive GoGo juice has a lot of trace elements and the plants respond well to it.
I have a bio press for the fish bacteria and a tricoderma haziaum (spelling?) living in a sphagnum moss stocking in the lower rez for the biosevia. (should also be helping with the GoGo)
all readings are great except maybe the nitrate being high.
I was using a product called Charlie carp, it has a lot of solids and stopped using it for that reason.
of the 2 plants the gsc has very clean roots, the lsd.. Not so clean, and the test plant last time up and died, partially I believe as my roots dried out for a day :/ ( hazards of a system in construction while growing!)
going to get all the tests I can for these these important elements which some can be lacking in AP
I also use diotomateous earth as a aquarium medium which has a lot of trace elements
I think the lsd may have a root problem more over anything else, blocking some uptake? (its not slimy or smelly at all)
all said though, she was mutant from the start (self topping)
gsc will be the test to get right as there has been no issue with her progress so far, so will hopefully see her get to her full potential!
I am changing out the dwc to fytocell recirc systemnwxt grow and will only be using particle free nutes.
many thanks, will look into what you have suggested!
any thoughts on additives/stimulants etc that might help?
(edit) oh, I have banana skins ground up and sprinkeled on the media for P, not sure how well it works but that is all the AP guys do for P

Howdy Fet', pardon the delay... been doing emergency harvesting due to shite weather!
..is that curling from earlier? The yellowing could be part of P defc., the dead patches are classic P defc. symptoms,... S (often causes overall yellowing, tops worst) and Fe (less likely, newest growth hit worst and first) might be short too,... I'd say the P defc. is the main culprit, from the looks of the low bud building,... As for a fix, it's a bit tricky I know, to find a good PK booster (high P-K #'s) that's safe for the poop machines- 
-- what fish do you have, Tilapia, carp,..? The OG is great, but it's no panacea for boosting bloom PK sadly,... And foliar isn't the best way to supp' bloom nutes, especially K... I don't see definitive Ca/Mg defc. symptoms at least!
