Reverse Osmosis Grow *HELP*

Hey dudes! Recently switched to an RO filter as my local water is very poor quality, and all my plants seem to be freaking out. I’ve been adding the fox farms “flower kiss” to raise the ppm and adjust ph for every water, with a full synthetic nutrient regiment once a week which I’ve done for a few grows with great success, in fox farm ocean forest. Can’t tell if this is deficiency or burn, any help identifying and fixing would be greatly appreciated.

Looks like multiple issues, P & K deficiency or lock out for starters, possible Ca. Def. too. The plant looks both nutes burnt & deficient.
How often do you water?

Usually 2-3 times a week, every few days when dry. I believe they’re receiving absolutely everything they need, past grows loved this nutrient combo, only new introductions are the RO, then the flower kiss to add a lil somethin back while watering in between weekly feedings.

Are they in 5g containers? You may be watering them too much.
I have no idea what is in the nutes you use, doe is it include Ca. & Mg.? R.O. water lacks it.

Ye 5g, I don’t have signs of overwatering from my past experience but I’ll keep an eye out. I believe I’ll be harvesting in a few weeks, but my veg tent is suffering too. Nutrients in attachment

Do you feed them with cal\mag?

Yes, or at least that’s how the flower kiss was sold to me. I also assumed it’d be available in my 2 part feed, starting to wonder if the flower kiss concentrate is too strong.

It's for foliar and therefore is weak. No Ca noted.
