It's a Calcium/ Magnesium deficiency, for some reason plants under LED lights crave more Cal-Mag.

K deficiency?
in the last pictures you can see what to me look like an early deficiency of K. Since she is in the first stages of flowering I would say that's the case, reading the literature online i noticed a lot of similarities, what do you think?

More rusty spots
See this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing. Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.

Nutes in flower
Anyone have any feedback on running high ppm in flower with RO water? Does SLF-100 help flush unresolved nutes? My first grow but I think I'm blowing it, please look and tell me what I'm doing wrong.

Brown rust spots on oldest leaves
Brown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?

Should I flush? (Overfeeding)
I think I have overfed my 2 dwarfs. Theyre showing signs like very stringy skinny new growth and yellow leaf tips. Theyre still growing and I dont want to stunt their growth, so all I want to know is if it is necessary to flush. Please tell me how to flush if so, thank you.
