Yellow Leaves - Purple Kush Autos

[Sgt Peppercorn]

HI
-first time auto grower, used to growing photos-

I have 3 PK autos all 37 days old growing in 3 gallon fabric pots. 40% amended soil from previous grow( bone meal and Epsom salt and d.lime and kelp ) , 30% compost and 30% perlite.
They each get a liter of water every three days that has sat out. I add cal/mag at half strength and make sure that the waters ph is at 6 - 6.3.
Did a soil test and the soil is at 6.8.
I have fed them once so far at week 4 when flowers started. 4.0.1 at half strength with some molasses, cal/mag at half strength. PPM 502. PH 6.2
At one liter of water per plant there is not much run off to measure.

Using 2 LED lights at 30 inches above the canopy. Temps with lights on 25 - 28 C. Temp with lights off 20 - 22 C.

The yellowing began just before the first feeding and just after they started to flower. I figure even though I was gentle doing the lst, I slowed her down a bit, but I can't figure out what the problem is. It looks like she's over fed but my experience is with photos only. I'm not a big fan of feeding weed. I just figure the soil should be the provider.

ANY help would be appreciated big time. We really need these girls to provide us with a little smoke while we wait for our photos to mature. If I have left out vital info let me know and I'll correct/edit

Thank You, Stay Safe

It looks like more k is needed with a bit of nitrogen also make sure ur picking up the pots bc mine drinks 64oz every day urs should be needing water before 3 days if it's drying out it will eat itself and do wierd shit anyway @ 30in maybe a bit to far away the older fan leaves that don't receive enuff par will be cannibalized by the plant. Well either way good luck sending good karma and vibes ur way

Is the yellowing of leaves mobile ? Like moving up the plant? Any burning of the tips of the higher leaves? Your in early flower and that could indicate a K Deficiency which is possibly from too much cal/mag in veg causing a Salty soil and locking out the potassium. I would flush with plane PH’ed water and maybe water with a tea made for early flowering.
