If it is taking forever to dryout, your mix is way too heavy.

PBP grow has 3-2-4 so it does have some P.

What would Gypsum do for me?

The water uptake issue is a bit puzzling to me. When transplanted from their 1 gallon trade pots to the 5 gallon pots, they were quite root bound and had a vibrant root system. It seems it never expanded into the new soil, as the soil around it is very loose. It's also not absorbing moisture very well from what I've noticed.

I would argue you should take a soil analysis and figure it out, correctly. But in the meantime...

Apply epsoms at a .8% solution foliarly. NOT TO the soil. That will help you shed some N.

Apply gypsum or low fat milk to the soil to get an available Ca quickly.

Do you have a ppm meter? Can you do a slurry test?

Get a P source, ideally phosphoric acid. What do you have available? Earthjuice has a good 0-5-3. I would prefer no K (the 3) if possible. A good liquid bone meal maybe?

if you have twelve inch plants in a five gallon pot, and you water to runoff you're doing it wrong. that's almost enough water to last until flowering...

Slow growing, even slower drinking (watered once in the last three weeks without signs of drooping)
Recently given Botanicare nutrients as follows per gallon @ pH 6.5

5.5ml Pro Grow
2.5ml Cal-Mag
7.5ml Liquid Karama
2ml Hygrozyme

Showing tip burn on newer growth as well as some clawing and twisting. They're small, probably 12-16 inches in height with 4 shoots each.

Prior to this watering all they've received is plain tap since transplant. I don't understand what could be causing their sensitivity.

i'll bet that dolomite you added is burning them also can raise ph of peat base plus your supplemeting cal mag and pro mix has dolomite already
