Longest established. The rest will catch up. Not replanting the tops for now so everything will be dull for a bit after each cut but want that investment in root structures maintained to lean out the soil as much as possible.
T5’s are the only thing that can deliver the next level after this but need to give things a fair run under this arrangement first.
The point was never to succeed, it was to find the fail point against adequate Co2, adequate nutrition and ample filtration. I’ve used standardised products which should mean everything I’ve done so far is replicable and a possibility for anyone wanting to try.
The T5’s then open up the opportunity to play with the red and blue spectrum bulbs. Tom Barr and Dennis Wong have had a good play with these, only seems fair to give it a whirl and see what’s what.
@Jayefc1 just a suggestion but have you tried dosing only potassium (ADA brighty k neutral / Easy-Life Kalium Potassium / Potassium Sulphate K2SO4 salt) in place of your macros NPK for a week or two to see if you can tease out some colour? Your substrate will probably cover your nitrate and phosphate for that period without any penalty. If it does just switch back to EI macros.
Yes @Jayefc1 , or you can just make up a small bottle of just K2SO4 on its own to try for a bit.
If you want you could mix it up with MgSO4 for a source of additional magnesium as well. But leave out KNO3 and KH2PO4 to omit nitrate and phosphate for this mix. If you’ve gone heavy with root tabs there’ll theoretically be enough Mg, N and P in the soil/tabs anyway so all you’re doing is changing the location the plants attain them from.
Given you’re using tap water there will still be nitrate and phosphate in that too so it’s not as if you’ve removed it entirely from the water column, just reduced it.
Il.just dose the 2 salts straight to the tsnk for 2 weeks see how it goes no point making a mox for such a small amount of salts and as i chef i have the scales to way .1 of a gram.so wont be to hard to work out how much i need
Cheers @Geoffrey Rea for the help bro
