How long does it take for new leaves to stop being affected and for it to turn around? A friend said about a week grace period. I was going to do a soil slurry shortly and see if the ph is too low or high.
I did a soil slurry. Unsure if I should have gone down farther. People say too, but worried about roots.
Your tops and buds look fine so I'm pretty sure you don't have low anything. And there's not that much damage to the lower fan leaves so I wouldn't be doing anything drastic at this point.
Slurry tests are ball-park at best and soil from the top couple inches isn't showing the true pH of the root zone where it counts.
The proper way to get a closer to true pH reading is to soak the pot to saturation with water but don't check that runoff. Remove that runoff and let the pot sit for at least an hour. Overnight is best so that any chemical reactions have stabilized. Then add more water to force some runoff into a preferably clean tray and test that. I use pH Perfect nutes and RO water so never worry about pH.
I don't really think you pH is much to worry about. Your water must be pretty soft to have a nice low pH like that. What is the ppm? It doesn't go through a water softener first does it? That'll kill plants.
Our house water comes out of a dugout on my property and is pH 8+ and 400ppm so we buy RO water for drinking and my plants. The minerals in hard water like that build up in the soil and lead to uncontrollable high pH and toxic salts buildup that shows up half way thru flowering and starts burning up the leaves making them all thick, and brittle. They go yellow/brown all across the leaf unlike nute burn that starts at the tips and edges.

So are the roots white or brown?How long does it take for new leaves to stop being affected and for it to turn around? A friend said about a week grace period. I was going to do a soil slurry shortly and see if the ph is too low or high.
