Burnt edges / yellowing
What are all these burnt edges from? One of the burnt leaves is from the perimeter, so I'm not sure how it could be receiving enough light to burn. I also have a small amount of yellowing towards the bottom. That's normal during flowering if the low-light leaves die, right? Thx

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 :)

I think I'm closer to week 7 of flower than I am 6, debating if I should flush.. The girls leaves are slowly burning down the sugar leaves closer to the bud, so I'm wondering if it's too early to flush.. Everything looks pretty good other than that, I think..

Yellow leaf tips in weeks 2 and 3?
A few Yellow leaf tips? And a couple of brown spots? Those symptoms only on both smaller girls not the larger. Were all cared for and watered in the same way. Possible light burn?

Why do several of my leaves look like this ?
I be had quite a few leaves that look like this , I’ve taken them off the plant because I’m not sure what it is. Do you all know? I just want to make sure I’m not experiencing pests or mold.

continuing nute burn or deficiency now? biobizz lightmix +organic nutes | runoffs EC 1.8-2.5 | PH 6.3 | DLI 45
cca 10d ago, I found early signs of overfertilization. I reduced nutes, but yellowing continued. After a flush 2d ago, things got worse (now also edges browning). I now suspect potassium deficiency or still nute burn. Next watering is near—should I flush again or feed properly?

I have been having trouble with my leaf tips and edges appearing yellow and then turning brown. At first it was just the bottom leaves that were affected but now more of the top leaves have the burnt appearance just not as extreme as the lower leaves. What can I do to fix this?

Nutrient burn?
The leaves on my two plants are starting to show signs of burning. Is this nutrient burn? I have no added nutrients yet but I am using Happy Frog soil. I’ve raised my lights from 24 to 28” in case it’s light burn. What are your thoughts and recommendations?
