Auto Devil's Kiss Deficiency HELP!

Hello all! I am a new grower and am in need of help figuring out if one of my pals has a deficiency. Yellow spotting is occurring all over the entire plant and the the lower leaves have accumulated light brown spots. I am using fox farm ocean forest and have auto feminized devil’s kiss in 5 gallon root pouches under a mars hydro 2000 watt tsw LED. My tent size is 3x3x7ish and does have the proper inline fan/exhaust and humidifer keeping the range between 50 and 60% at all times. My temp stays between 70 and 75°F. For nutrients I am using the Flora Trio and Cal Mag. Nitrogen or phosphorous deficiency maybe??? Any knowledge would be greatly appreciated. I will share photos.

How many weeks have they been in OF soil? Do you test ph in and out?

They have been in FF since the very beginning 5 weeks total. Water going in is usually between 6.0 and 6.5. My runoff usually tests between 5.5 and 6.0. This a.m. it tested 5.7ph.

I would slightly increase cal/mag and increase my ph for water going in to 6.5- 7.0 ph. Soil by nature makes your water more acidic overtime.

Tyvm. I will try this, give it a few days and come back with shown response in photo. I appreciate your help highly. Strikes me odd that only one out of 5 wanted to act this way :confused:

I have 4 amnesia and I feed them the exact same thing . But one plant is always slightly nute burned. Every living thing is slightly unique.
