Help with a leaf diagnosis.

I checked my growweedeasy chart, and don’t see this problem, or at least I don’t think this is a nitrogen or iron deficiency. I dunno. Need help.

Week 6 of flower
600w
Tent
Coco in 3 gal pots
House and Garden nutrients
Temp avg 80
Hum avg 45

This is what I think is my problem.
1.) I stopped using Cal-Mag about 2-3 weeks ago.
2.) I began giving H&G Top Booster (Phosphorus and Potassium) 2 weeks ago. At half the recommendation.
3.) I began using H&G Top Shooter (MORE Phosphorus and Potassium derived differently. Interesting.) 1 week ago. Again, at half recommendation.
4.) I stopped using nitrogen 3 weeks ago.

I think that the point 2 and 3 are what’s going on, that I have introduced late flowering nutrients to the plant, and it’s reacting accordingly.

I believed it’s a natural reaction and I don’t need to over react.

Help.

good fu#@en eye doc! all i saw is deficiencies and would say check ph first. how you knew it was ph at a glance before he mentioned 6.2 is beyond me. bravo
Decades of looking at plants.....I could see it was advanced by what the damage was and how much there was. Classic Ph lock outs! It was going down hill fast.

sorry to step on this thread,but what is everyones thoughts on optimal ph for promix?
Like any hydro.... 5.7 - 6.2 I have never been a fan of going lower then 5.7 BUT some find happiness by starting at 5.5 (shudder)..... Ed Rosenthal qualifies 5.8 - 6.2 as optimal - I liked 5.7 as my low end set point. This was used in soilless, Ebb, and DWC - RDWC.......I don't play with hydro anymore....All soil...... I might play with my 2x2 Ebb table for shits and giggles again though....Maybe this summer...
