Is this a cal mag problem

I walked in to my garden the other day and this happened I been away from growing for a while trying to get back in the swing of things but the leaves are curling and they are burning but the day b4 all this happen I gave them a pretty good flush with straight RO water I also totally forgot to ph the water the ph in the RO water is 7.5 and then later on that night I sprayed some Nuke’em on them but it certainly couldn’t of been that it seem something made the ph swing high I would assume the RO water should I saturate the soil with ph nutes to try to correct it or should I go with a foliar feed with cal mag or should I do the flora flex foliar

I had a similar problem with my girls, I thought It was nute burn at first but after looking into it more i found out my new house has a massive water filter that sucks out all the minerals. I started adding some cal mag and they bounced back better than ever.
If you got a heavy filter or R/O water It’s more than likely a cal mag issue.

The ph how would I adjust do I just wait til I water again and correct it then I was reading some where to use a lower ph when I water or feed like a 5.5 or something similar like lower so I will blend and make the ph drop

Add cal mag to next watering. Bring the ph to 6-6.5 ...... which is the best uptake ph for mag..... You should be fine. The burnt leaves won’t recover but all new growth should be happy
