Most of the leaf stems are red and i can see it etching into the main stalks. I've read that this can be a phosphorus lockout, does anyone have any tips or suggestions? Ill update with pictures of the stems soon.

Difficult to say for sure because you have stripped all the lowest leaves which would have given definite signs of which deficiency if any you are dealing with. Your upper leaves aren't really showing signs of deficiency. I agree with Spinner Caribbean your leaves are very dark green. Once in bloom your plants use less nitrogen if you keep adding it and the plant is not using it build up of this element could lead to the dark green leaves. Dark almost blue green leaves and dark blotches almost black with red stems is also a sign of a phosphorus deficiency. In terms of genetics red stems could be a trait of this particular breeders strain each seed contains different percentages of each trait. Also night time drops in temperature can bring out reds and purples in stems. While the red stems are a sign of phosphorus deficiency it is also a sign of potassium,magnesium and sulfur deficiencies. Back in week 5 your plants were showing signs of a sulfur deficiency. Yellowish leaves with red stems and purple streaks running up the main stem is a sign of this deficiency. You mentioned having soil ph issues I would suggest doing a flush with plain water with a ph of 6.0 to 6.2 then read the ppm and ph of the runoff initially coming out(First run off) This will give you a good idea where you stand. While using the runoff from your pot will only give you an approximate idea of the soil ph keep in mind that if the water goes in at 6.2 then comes out 5.8 you have a 4 point difference this means your ph is actually lower probably in the 5.4 range which is a potential cause for the lock out. If the run off is over 1600 ppm I would flush to get it down into the 1000 to 1100 ppm range. Then the last quart of water use your normal nutrient routine. Let her dry out a bit before her next watering. I would concentrate on giving her a flush then concentrate on bud building by continuing your nute regime adding the Kool Bloom to give her the extra phosphorus and potassium. You can try to adjust your future feed /waterings ph to 6.2 to 6.5 and keep checking the run off. Hope this helps to be honest I don't really see any major issues other than a bit of potential ph lock out.👍

I think you are correct in diagnosing phosphorous deficiency or lockout. If you go back through your diary, specifically week 5 in veg., you can clearly see streaked stems all the way up to the new growth - this is a lack of phosphorous. I have multiple Laughing Buddha grows past and present, and all exhibited the same purple progression if not fed enough phosphorous. Some plants use nutrients differently, and Buddha always lacks phosphorous. The streaking won’t go away once purple, but you can try to stay ahead of it in veg. In Buddha’s case it is not genetic and regular feedings prevent purple, streaked stems, purple petioles, and dark leaves. I can not accurately guess if you have deficiency or lockout, I just think it lacks phosphorous. I will point out that Iron excess locks out Phosphorous uptake.

Dark green leaves in flowering , purple petiols, seems that the flowering process is slowest than usual : I bet on a nitrogen excess ! Or maybe your plant have that phenotype , many haze that I grew had these specific trait like the dark green leaves and the purple petiols ; your plant is a GG which is a mix between a sour dub and a chem sister , the chem sister have approximately the same lineage than the Chemdawg and the chemdawg have Sativa inside ( and is originally a plant that has been grew from a batch of bag seeds so we don't know the sativa % in it ). I can also tell you that the petiols are purple since week 8 ( visible on the pictures ) but I bet you can see them sooner in the plant life. To finish it is not a phosphorus def as even if the leaves are dark green even blueish , it's been more than 5 weeks and you should have seen some necrosis on the leaves if it were a phosphorus def
