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.

Day 20 Flower. Leaves curlingLeaves curled over 12 hour light cycle. Ph 6.0. Ppm 950.
I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this.
I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

Pre-harvest CareMy question is related to harvest techniques. I have seen where several diaries talk about water restrictions the last 1-2 days prior to harvest and also about placing the plant(s) in the dark for 4-7 days prior to harvest. I would like to hear from the master growers on it. TYBuds. Other

What do you think the problem could be?There’s something going on with some of these plants and I can’t seem to identify the problem so far. I have been doing a lot of research and I’m in a process of elimination at the moment but the plants growth hasn’t been affected. I will continue to try treat the problem.

Help: potential over fertilisation or over waterningI used Biobizz bio grow, 2ml/L and sprayed them more than usual. The tip of the leaves is getting yellow. 2 plants have the leaves pointing down and seem more textured and tick. The other 2 (the biggest) seem better, but the yellowing of the leaves is more evident.
