Need help diagnosing

[Josh]

Hey everyone, just wondering what deficiency/toxicity you might think this is.

Only a couple leaves at the top of canopy show it so far. The rest of the plants are fine but do look a little dark green, so I'm leaning towards nitrogen toxicity.

Day 26 of flower, temps have been at the most 27 c with the lights on. Growing in soil using fox farms nutes at 3/4 strength

Thanks!!

Thanks for the reply hobbit, I've been giving a dose of cal mag for the past few waterings. Should I up the dose even more you think??

I feel like tap water should already have a descent amount in it, but I gave a full strength dose this time. I'll keep you guys posted

Yes, hobbit is right. Try not to overdose as it can burn the plants and cause salts build up.
Affected leaves won't recover but keep an eye for fresh ones.

Maybe worth calibrating your Ph pen to make sure it's in range (if you haven't already)

To be honest I had 3 BlueLab pH pens and they all showed different values.. calibrated in same fluid one was showing 5.6 other 5.7 and third 5.8 lol

Lol, figures. Just calibrated mine so hopefully it's correct
