what nutes are you using? it might be worth trying something else that is a guaranteed "good" cannabis nute.

are you near a grow store at all?

@Aqua Man the yellowing almost looks normal for new growth but if you zoom in on the edges of the leaves that are yellow, they are really dark green. that's kinda weird IMO

Not normal. I don’t have a pic but before all this there was just a faint hint of yellow. It had calmag at 150 ppm.

and that looks like a N defic. nothing to do with cal/mg i think. either you are nutrient locked or your nutes need more N.

I always had very good results with the "Lucas Formula" and some epsom with any hydro style with water as a substrate. Very stable and good with most tap water.

that's what i think. pick up a bottle of floranova bloom or the micro/bloom and run Lucas. it would at least eliminate his nutes as a problem.

Ok that ph is holding rock solid. So let start this over again if you don't mind. Looks like possibly high P maybe k or sulfer/iron deficiency. But again this is likely from past.

Iets try to get this balanced out I think I had you go to much oh up. That ph is to stable and kinda leaning to high K causing some micro issues but again imo it's to fast to see that. Going to go at it a bit different and more reserved. I have never used ph up to buffer as I said before, I only used raw salts like potassium bicarbonate which is what ph up.

1 last res change gonna cut way back on the ph up etc and work up as needed. That will avoid complete res changes.
Fresh res temp adjusted add 1ml per 5 gal of ph up. Add 1 g per 5 gal of mag sulfate. Then add 300ppm of nutrients at 50/50. Then ph down.

Sorry OP I had not used ph up in liquid form as a buffer before so I feel it was over done on my advice.

Ok so I just flushed out my veg room. So I can try the lower ph up on that tonight.I have clones rooted that need to go in to a system. Normally I go .5 ml /l Ca mg and 300 food. Greens them up in 4 days. But ph is always climbing so will try your reduced formula of ph up. Thanks.
Beer and joint time.

You can add 1ml per 5 gal cal/mag just to bump nitrogen a tiny bit.
