Started Flush - Rust color on edge of sugar leaves
So these are starting week 8 of flower - I just started flushing these- they’re in coco. Within the last day or so they’re developing these rust colored orange areas on the edge of sugar leaves. Is this just natural during flush with coco? Or what’s going possibly goin on? Thanks

Do you see nutrient burn? I'm guessing (after some forum assistance) they are underwatered. Shame on me! So nutrient burn or underwatered?

I don't think this is nute burn...
So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?

Calcium deficiency?
I'm not so sure if it's calcium deficiency, what do you think? Watering 100ml of water minimum. Using 1ml calmag/per 1L(and other nutrients like N,P,K)..soil comes nutrient free. Should I water her more and add more calmag or is this a different deficiency?

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?

Grower question
Any ideas what the issue could be? Few weeks into flower. Dealing with fungus gnats and have kept the population very low. Temps do get high, at most 95 (hot I know). I cranked down the lights to their lowest setting (100 true watts LED). I have adequate air flow.

Leaf damage and flower analysis
Asking for thoughts on leaf damage. I think there may be nutrient shock so I will be reducing PPM to 800 to see if that helps. I am confused by other problems seen on a few leaves. I also want to ask if I am getting close to harvest (check flower pics) since this is an autoflower

Bottom leafs getting dry
The last two pictures show some sights of deficiency after getting a little bit dry before repotting. Any recommendations: should I do something? I will definitely use some ph-down and water with 6.0 to 6.5 ph to help the microorganism get going :)

Why are my leaves getting brown yellow?
My leaves are getting brown/yellow, I saw online that it's a bad sign but I don't understand if it's under watering, overfeeding, underfeeding, light burn ecc? Thank you so much for the help first time grower.
