Hi @TheCode by the yellowing between the veins of the leaves it seems to me to be lack of nitrogen. Plants consume a lot of nitrogen in the first weeks of flowering as they stretch. it seems to me that you cut a good dose of nitrogen too early, at this stage it is not worth correcting to not affect the taste of the buds. by the appearance of the trichomes it seems to me that 2 weeks maximum and the plant is ready for harvest. good luck mate 👍

I'm guessing the listed TDS of 600 ppm is not correct as the nutrient ratios listed do not match that ppm. Your nutrient ratios seem all out of whack don't know what's going on there.

Could be magnesium due to yellowing between veins and purple petiols of the leaves. You seems to under feed your ladies , with 1.2ec at that stage they are searching for nutrients so you have the magnesiul def + a Nitrogen def ( normal after a certain point ) also like you said the ph beeing 5.6 it's too low , you need a 5.8 ph at that stage and a 1.6/1.8 Ec solution (even more is possible but slowly increase as a julp frm 1.2 to 1.8 is too brutal ).
If the feeding is corrected the issue will stop spreading but the affected leaves will not recover

Well I could be wrong but I am seeing classic Magnesium def, the inter vein lightening is the dead give away as that is where its pulled from in a shortage.
Ph could cause this no doubt.

Starting to yellowSo I had good growth up until 2 days ago when the one plant started to yellow. I had them going 24 hours a day and I got grow dots mixed in the bottom two thirds of the pots. Could this be light stress? or could it be hungry?
