It just says in general. It looks like a serious book to
.
Post pics in natural light too man. Easier on the eyes and seeing any issues. Just for future reference.
Also that grow bible has a hydro section. It will discuss the ph requirements for soilless based media. I own the same book and a few others.

Thanks man, Ya I'm gonna grab some nice pics during tonight's watering, I'll deff post
Man I use 8 inch by 3 foot slabs and put only 3 plants in them. But you have to be careful not to water them too much. When they are small clones in 1 inch blocks put into the slabs, I only water them every few days. Same with 4 or 6 inch cubes, small plants you can't water them too often, although more often than the slabs. With 4 inch cubes when you first put the 1 inchers in there you might want to water 1 time per day. When they have roots out the bottom of the larger cube you can water them much more, like 5-6 times per day. In the slabs you want to be careful and not do it more than 1-3 times a day even with big plants. Some of my current plants are 4-5 feet and I only just switched to 2 times a day with the big slabs. Check out this guide from Grodan but ignore the EC concentrations they mention, they do not apply to ganja.
Ya it does seem like a good book was just wondering what the ph 7 thing was
It stated for soil in the paragraph. Your not in soil. Soils have buffers if they’re good soil anyhow thus why I never check soil ph. I only check my hydro room. My soil room is auto pilot. Simply water and let it go.
