Potential causes and fixes for magnesium deficiency
My runoff EC and PH are normal and I am adding calmag to every feeding so not sure why I might have magnesium deficiencies. Aside from giving them just a calmag feeding and foliars, any tips on what I can do and why this is even happening?

Nitrogen Defficiency?
I’m growing with super soil and amendments for this grow. Looking for the Autumn Color Effect. I understand that you need a nitrogen deficiency to get this, and if timed right it shouldn’t affect my yield. I’m on the 5th week and one of my phenos is pretty yellow. Is this okay?

Possible overfeeding nutes?
Could someone possibly identify the issue on that one leaf? I had another like that a bit worse that where the edges started to curl. They were fan leaves so I ended up removing them as they were a bit worse off. Doing much better now, only guess is too much nutes.

Yellowing of top fan leaves
What is causing yellowing of the top fan leaves? Started to happen to a plant that I broke by accident during LST. However around the same time I upped to 2ml/l and moved the light a little closer. My ph has also been high (fine now). No idea which one could be the culprit

Possible pH issue.
(15th photo) I've a few leaves which are not looking the best. Does this look like a pH problem or does anybody have other info? I have dropped a bit of lemon into this plant which is the only one with this issue which has not touched the other 2 plants under the same regime. Tx

Looking for clarification on the Flush time required for a RDWC grow? I have read this can be as little as 2 days of just plain water but should this also include CalMag if I am RO water? I assume the standard root rot treatment continues? i.e. OxyPlus, HydroGuard, Phytoff?Thanks
