Hello good people and happy holidays . Got some plant problems. First grow in a while now and decided to give Promix hp a go in 3 gallon pots. Im feeding with the AN line , ph 5.8-6.0 and run off seems to be the same . Its day 27 , deficiencies started showing about 4 days ago.. The feedings have been pretty light but im starting to think it could be burns or possible a cal or P issue.. Thanks in advance to anyone who takes there time to read this..

What lights are you using? I can't stress enough the importance of a soil probe either.
 
I have 2 clw solar flare 220w in a 2×4 about 28 inches above canopy, i had a accurate 8 probe but i felt it was a bit old ,didnt have faith it in..

I've used the same accurate 8 for 4 years now, it had not failed me yet. I'd give it a try and see what she's reading. I use promix hp alot.

Are you supplementing extra cal-mag I've noticed with LEDs they soak up the cal-mag.

Just noticed your pH is hi 5's low 6's? You need to be 6.5 to 6.7 has worked best for myself.
 
I do believe advanced nutes has cal mag in it I get this as well running an sensi grow and bloom on some phenos

Will do and yeah I started with some cal mag last feeding, I was hesitant considering a double grape on the same schedule is damn happy.. I'll try upping the ph but it seems people run the ph of promix at different levels lol

:toke: TB-- please fill out the patient form in the highlighted section above this one; c/p it here and fill in,...
I'm with GA6, a pH reading in-pot is needed to figure what the next step is, and it's a bit too low for Promix/peat...use that A8! --make sure the bi-metal tip is buffed clean, Promix is well moistened, not dry, not heavily watered; let it sit for 2 min. and read,....
Symptoms are mixed, makes me think this is overall longer term underfeeding,... testing straight run-off isn't an accurate way to get true in-pot pH, too crude, but it can at least show if things are way off pH in there, and it seems not- :thumbsup:- but verify!
... wasted lower leaves have been drained of mobile nutes, looks N maybe P related,.. higher leaves going bronzy-yellow, maybe P as well,... your feed sched'/dosage specifics we need to know,...

Sorry my friend ,haven't had a chance to post. Everything is on track , I do believe it was a case of underfeeding. As always I appreciate your expertise lol it has helped me out a few times in the past .
