good morning, I am a total noob with hydro (and pretty green with any growing tbf).... I bought a plantit Aeros 4... (4 bubble pots and a master pot that recirculates).... Planted my seedlings and messed it right up. They have been in about 2 1/2 weeks and haven’t really grown much, more so the roots just don’t seem to be growing quick. So... last night I emptied the whole system as much as I could (there was probably (5 litres left)... I made up my nutrient solution using ionic hydro grow, I used 120ml of hydro grow to 70 litres of water (less than a 1/4 strength and used ionic hydro ph- to bring it down to 5.5 (knowing the remainder left over was about 6.3)... using my blue lab pen my reading were 1.2 ec. That was 6pm last night, this morning I checked at 6am and ph has risen to 6.2 and ec has gone up to 1.4, but my plants do not look happy. I’m really struggling to get my head around this dwc business. Oh my tap water is 0.3 - 0.4 on ec.... Any more info please ask, but I don’t know if I’m doing it right or wrong!!
