Avg temp in veg box is 80* with 50-55% RH. It is in a 2x2x5 box with a 150W HPS and 20k lumens worth of CFL's. Plenty of ventilation, I am sure its the soil..but can I fix. PH usually in the 7.0 range, cant seem to drop it.
Melvan said:You've got ph lockout. 7.0 is too high. Plant isn't uptaking nutes, so you're all over deficient.
pcduck said:I would not use Holly Tone to control pH also has nutes in it..
Maybe a humic acid or fulvic.
Hushpuppy said:I just went back and found something that may serve you. There is a product from Advanced Nutrients called "Tarantula", that is made up of 10 different kinds of beneficial bacteria. I am sure there are other brands that make the same thing, but the key is that it is all bacteria which like to lower the PH in their environment. If you get this and add a small amount to your water each time, it should bring your PH in line to where it should be, and the bacteria will help release nutrients to the plants while protecting them from harmful bacteria and fungus.
