These are critical mass, they're approx 5 weeks old (from seed).
They started out in rockwool which was presoaked. They looked well the first 3 weeks until I put them in the Aeroflo.
Then two died, wilting extremely and never really recovering.
The others were droopy like on the pics and started to yellow at EC 1.4 so I thought it was an N def. I raised the EC to 1.7 Using GH 1-1-1.
Ph was always around 5.8, drifing up to 6.1 over the course of a day.
They started to show improvement the next day but the day after that it was worse. I researched and concluded that I should've used Lucas formula.
So I did a res change and had the EC at 1.4 at 0-1-2 (parts GH), I also put in liquid silica. The next day they were a lot better, greener and didn't droop as much Almost recovered.
Fast forward a day and it's the sames story so I again raise the EC to 1.6 but nothing.
They're getting worse every day, the yellowing is moving itself up.
The Ph is 5.8 and raises to 6.2 after 24 hours. It looks like overwatering/not enough DO :/
That may be because as you can see I'm using pretty big rockwool cubes, they barely fit the netcups and they never dry out.
Also that may explain the sudden improvement they had after the res change as the fresh water was higher in dissolved oxygen.
Because I didn't take the plastic cover of the cubes of until they were pretty big I fear they became saturated with roots.
Yeah and I switched the lighting to 24/0 from 18/6, but nothing really changed. It was just more convenient that way. I won't change back.
Don't know what more to say. Just look at those babies and see how they're suffering.
Purple veins, yellowing with green veins. Yellow leaves curling and dying. New leaves clawing and drooping etc.
Nurse my little darlings please! I can't sleep because of this.
