Weird problem in flowering. Getting very bad. Leaves brown/yellow and crispy

I have blue dream growing and have been using cal-mag and fix farms nutes LIGHTLY.

All plants get the same watering can and all get the same treatment.

All are displaying somewhat different problems.

I took a leaf off every plant (4) and took a photo to show. Any idea??

Overcooked in veg ,flower or both. Next time cut the nutes by 25% and you wont have these burnt leaves which will reduce final weight.

I'm wondering if you have a combination of P def and cal def, on top of nute burn. What's your medium and Ph if your not in organic?
The P deficiency I'm looking at the shine on the leaves in the picture with the leaves removed and layed out also the mottled brown crusty looking spots

burn and P definitely.

Calmag

Nutes burn and lockout

severe stress has caused reveg at one time.whats you ph?

This may help, I suggest you take note of the advice given by the other growers on here as well.
Best of luck !

If ur using tap water be careful with cal mag make sure u check ur tap waters ppm if its high I wouldnt use calmag tap has calcium usually...use Epsom salts for mag.....also like stated go light on calmag if using with fox farms cal mag is high in nitrogen and so is fox farms grow big ...
