stop using the 15-0-0-26 calcium nitrate,
go to about 650 of the 3/11/27 and add about a 100ppms of epsom salt, add 2ml per gal of cal/mag, keep water temp about 72 and ph at 6.0-6.2 check ph daily ....get some ph drops to check every now and again or when you have a ph swing to make sure the pen is accurate and before you add ph up or down when there is a big swing so you dont add ph up down when you dont need to if your pen went whacko on you.
pick off all the jacked up leaves.

yes the mag and cal mag are about the same thing along with the calcium nitrate but the cal/mag has less nitrogen in it. and or if the 15-0-0-26 calcium nitrate is actually 15/0/26 then I would guess that your adding more K than need be.

So I followed the above with real cal mag and came in right around 1000ppm so I’ll give it a few days and see what they do

Hoping someone can help me. I changed the res just before leaving a week ago for work. Had the wife keep topping off with RO water throughout the week. Just got home today and came home to the plants looking like this

just entering week 5 of flower and they now look rough

I Changed the res with the following

base -40ppm
Cal mag - 100 ppm
Epsom salts - 100ppm
Then ~700ppm of 3-11-27. (Similar to peters)

for a total of 1000ppm

I know they look rough. can anyone Tell me what the deficiency is? And how to try and correct it from Getting worse?

and most importantly how to prevent it the next grow?
