Please check the last pictures I have posted. This is about a week after transplant, and the plant also has burnt tips. Are the brown spots from something other than transplanting into hot soil? They are in KIS water only soil and I have only been giving well water, ph is 6.8ish

Is this more nutrient deficiency?
I believe the yellowing and brown spots came from the roots starting to suck up more water than the previous weeks. Do you agree that the Durban Poison had some nutrient deficiencies?

Brown Edges on Leaf. Bit of yellow and purple.
What could be causing this? And how do I fix it with GH flora series. It is only showing up on one bud site. But I believe its getting worse. I also noticed other leaves all of the jagged edges are slightly curled up

Brown spots on tips of some leaves
4 leaves affected on only one plant. All plants are receiving same feeding and are from same clones. Based on photo and googling it looks awfully lot like P deficiency? I'm still in vegetation phase though. I'm feeding with Advanced Hydroponics Grow + Bloom + Micro based on chart

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.

Brown dark spots on fan leaf
Any clue what this is? It only appeared on 1 of the plants and only on 1 of the fan leaves. The brown color has kind of a metallic shine to it. My guess is that it’s a Cal. def. I also suspect it might be a Phosphorus def. as the plants turned dark green the last few days.
