Quote: mhbound said: First of all I wouldn't be feeding them yet. And you have to know the ph of your mix and water or you won't be able to grow hydro. Last, your ph is a little high. You need to know the ph of your coir, water with a ph of like 5.8. Use the ph for hydro not soil.
Also temp and humidity are very important but I don't think that's your problem.
I would have to agree with this! Feeding already is bad. You want your ph to be more like 5.5 for hydro. orangish yellow but not red. I also noticed when using the drops and actually getting a ph meter was a huge difference. What the drops read at yellow was like ph 7 when I got my meter. They were pretty far off.
