I checked the PH and it's @ 7.8. From what I'm reading that might be the problem. I have "PH Down" (sodium Bisulphate) for my hot tub. Can I use it to lower the PH in the water & Nutes mix I'm giving them? I'm using ferti-lome 23-18-16 for my bloom Nute. Is thet too much Nitro?
Steelwool Reviewed by Steelwool on . Any suggestions? I just went 12/12 3 days ago when I noticed some yellow patches on some of the lower fan leaves and the upper/newer leaves seem to be a little skinnier. They all also seem to curve down a bit. It's not getting worse but it's not getting better. (See pics) Should I change the nutrients? Any suggestions? Rating: 5
