Maybe add some pelleted dolomite (PH up buffer) to the lime green one, not a lot, top dress then water.
For PH down buffer I use pelleted sulfur, my pots are larger than yours. The sulfur mixes with O2 and water over time creates sulfuric acid (a common PH down)

It is the same soil in all the pots. I do not know why the wide range of ph.
There were at least 3 pots where I buried the peat cups into the soil, and I would assume that the peat cups would lower the ph at least for a little while. However, I am almost certain that this particular pot was not one of them.
The pot where you are diagnosing wind damage is a good guess. It is actually transplant damage. (Plant #2, clockwise from the upper left.) I lost limbs and leaves while trying to get the root ball out of the pot.

From what I could gather from the hamburger menu, the ideal ph range should be 6.5-7.0, slightly acidic. My (proposed) method of adjusting ph is to use the bottled products ph up and ph down, which I don’t have yet but when I do have them, my plan is to maintain my same watering schedule while adding ph adjusters to the water. Is this what you recommend?

BTW I see PH issues in 4 of the 5, the other has wind damage.

PH in soil while vegging should held at 6.2-6.5 in flower 6.5-6.8. I would start with correcting the PH.
Is it the same soil in all pots? IF so then why the wide range in PH?

Looks like things are going better. I would stick with the new watering schedule but I would try to get that PH up. 6.1 is low for soil and can lead to deficiencies. Deficiencies can lead to yellow leaves.
Considering the start they had I wouldn’t go crazy, just give ‘em some time and focus on correct ph and watering appropriately

the plant at the left front is the topic of my question. Its leaves are lime green to yellowish. It’s ph is 6.1. The other plants have ph of 7.2, 7.3, 7.0, 7.0 (from upper left going clockwise. The 6.1 plant then is the last reading going clockwise.)
I couldn’t find where a low ph would cause the lime/ yellow leaves. I’m betting on watering.
I think that this one just hasn’t recovered yet from overwatering. I don’t think the light color is a new problem, it just hasn’t recovered yet. The question I have is should I add ph adjuster or nitrogen (or another nutrient) or give it some time?

Thanks
p.s. I do have the plant on a much better watering schedule now. It’s been 3 days since I watered it, and the soil is still moist around the plant.
