Full tent update on my journal in a few.

These are at day 22 of flower. The rest of the tent is not having this problem.
I have compared this with pics of every deficiency I could find but am still unsure. They are in a 4x8 tent under 2 1kw air cooled hoods. I'm moving 540cfm pulling thru the carbon filter and pushing thru the hoods and out of the house. Temps stay at 78-82 light on and 68-71 dark. RH moves between 52 and 60% Hoods are currently at 18". Tent is cooled with fresh air from the room it's in which is cooled by a 10kbtu window unit.

They are in Promix HP and on H&G A&B soil schedule.

I've seen pics of plants that are by temp flux that look like these but I think my temps are in line. Someone has suggested CO2 issues.

Any advice will be greatly appreciated!

Also... Intake is a passive 6" that come right from next to the AC unit. 3 Fans inside, 1 over the canopy and 2 at floor level. The tent has a lot of negative pressure when closed. Even if I dial the fan back to low on the speed controller for the big inline.
 
Looks like they need a flushing to me. I'm thinking toxic salt build up causing lock up etc... Going to need some more info like PH and ppm's to start troubleshooting though...

Thanks Fred! I knew I was forgetting something!

Feeding with tap water that begins at 7.8 and 16ppm. I let the water sit for 24hrs before using it. After mixing nutes at 1200ppm the ph is 6.1 and I lower it to 5.8. On water only days I just ph to 5.8 and go.

Runoff at last watering (2 days ago) was 6.3 and 480ppm.

Dam you have some little piggies there 1200 in 480 out.I was thinking lockout 7.8 PH going in is a little high. try keeping it at 6.3-6.5 range after you have added nutes.
