Grow Mediums Slow Seedling Growth rDwc

Only to make things worse I walked into the maintenance today and the CO2 was reading crazy like 8.000 ppm!!!!
The solenoid on the CO2 cylinder is malfunctioning and even when the controller powered it off it stayed open ... crazeeee

Man... I was reading up on the current culture website. My diy rdwc is a copycat of their undercurrent 4 bucket system.
Only difference is I use electrolysis instead of air stones now.

And they have a feeding chart for super Oxygenated systems like these that asks for a maximum of 350ppm on PEAK flowering !

I guess I was stunting the hell out of these plants that's why they never looked perfectly healthy.

What the hell.
Anyway, nothing to lose now, only learning and getting more experienced, so I will flush and refill with a weak 350 solution and let it sit for the rest of the remaining period.

i grow plants in various stages. i recommend u use that system as your main hydro for mature plants with the highest ppm. but have at least 2 other smaller hydros for seedling and young plant ppms. unless its the first run. i guess individual plants can be fed high ppm but when theres plants in various stages of growth its according to the youngests ppm. u grow many at a time so u gotta not over feed like me.
