You shoudl be looking for runoff in the high-6 range, like from 6.7-6.9 for soil.
Claw leaves can be a few things, the most common being rootbound plants and too much nitrogen. Make sure you;ve got about a gallon of available root space per foot of plant stem.
stinkyattic Reviewed by stinkyattic on . Ph level of run-off.... Hey guys, I was checking Ph levels of run-off today and had a few variations. What r your thoughts? To high, to low, okay, perfect? What do I need to do to adjust if necessary? All of my girls are in FF soil with a heavy mixture of perlite added, and I am following the FF feeding schedule using all FF nutes. I occasionally add SeaPlex about once a week, and use Molasses on non-nute days. All plants are under a 400w HPS. ( I am using a digital Ph pen to get readings) Big Bud: 30 Rating: 5
