Brown spots

started grow question 6y ago
I pride myself on never having any leaf problems, until now. Noticed some leaves have a brown color on the outside of them. I'm thinking it's from the foliar spray. I been using it once a week at lights off and only 1/2 dose.

Nutrient lock out?
Well watered my plants with great value drinking water. Ph 4.11. Didn't check ph until week 3. Currently upping it to 6.5 after I found the issue. Does this look like nutrient lock out? They were in root Riot starter plugs. And I fed the some clonex and great white microbs.

Harvesting a struggling plant or just letting it fight
Can she be saved or just flush her and harvest what I can? She doesn't appear to be happy. Has some CBD genetics so the lack of trichomes don't worry me. Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.

Having some nutrient issues. A few leaves are yellow with brown tips (first couple pics). I also had some nute burn a couple weeks ago after switching to GH so I lowered my feedings. Now I’m confused if it’s an excess or deficiency or something else? Any help much appreciated

I have 2 feeds left before I start the 3 week flush. With the state of the nutrient burn, do you think I should start flush now? Or feed half usual nutes for the last 2 feeds? Her leaves will die anyway during flush so that why I'm not so well worried about the nutrient burn.

Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!
10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.

Leaf diagnosis: nutrient burn or deficiency (or both)?
he leaves with the burnt tips appear to be more prominent at the top of the canopy, only affecting new leaves. A handful of these leaves look a little twisted. Meanwhile, the yellowing leaves are more prominent in the middle of the plant, just below the canopy

Rust/dead spots
This girl, was overall stressed out from the beginning. Lights, overwatering, ph , wind burn, you name it. Either way all of the plants have long recovered. Still stunted tho. Plants have only received one 1/4 dose of veg nutes. Are the spots from lack of P and K?
