That looks like spider mites. Check the undersides of leaves for them.

Yellow leaves
Hello, take a look at the pictures please. Leaves are turning yellow and curl. Is this a N burn, or a deficianty from some mineral? Or is this nutrient lockout? Plant does grow well!

Leaf Diagnosis
Could someone help diagnose this leaf problem. It's less than 2 days old. Aañnnnnd, 2 days ago I accidentally set the ppm to 1700? I've since dumped the solution and got it back down to around 700 ppm. I'm hoping someone give me some triage pointers. Should I trim those leaves?

creepy crawlies
I got creepy crawlies. Clipped the entire leaf, mixed abt 3 drops of neem oil in 100-150ml tap water and sprayed the f*ck out of it. Then I checked the rest of my plants, found nothing but decided to spray them anyway. When should I re-apply? Any adverse effects of neem oil?

Soil pH is surprisingly high. What's the best/safest way to lower soil pH (without eliminating nutrients from dry amendments)
Granite Runtz #2's leaves have started to lighten in color & develop rust spots/mottling. Troubleshooting this, my soil pH is in mid 7s; I always pH water to 6.4-5. Will daily watering with ~pH 6.0-2 be enough to lower soil pH sufficiently? I wonder if this also affected growth?

Cal mag deficiency? White leaves
Does the whitish leaf in the last pic look like cal mag deficiency? I just started adding it along with tiger bloom. They don’t seem to have powder on them like mold, just seems like the leaf is going white from the inside

9 point leaves
So I noticed that my Zkittlez plant has nine points on some of the fan leaves, now I've been told this is a sign of a healthy plant. Can anyone confirm this?!?

Leaf Discoloration - Hopefully Nothing
I'm looking to rest my concerns that these removed fan leaves from lower/center canopy are not simply just appearing so due to lack of light and prior plant tie damage. Focus on the yellow/brown discoloration, actual physical damage is accounted for. More details in main post.
