New Grower Help! Plants turning yellow with purple stems at 6 weeks

[MaInEgReEn]

If it was me, I would flush the hell out of it. Give it phd water. 6.0 during flower. They uptake nutrients better at that range. Start feeding nutes half normal strength in a week and slowly work it back up. Thats what I would try. Looks like ph lock to me.

...Maybe, but until he gets a reading, it's a dangerous guess to treat for it,... The organic nute's are less likely to cause major pH snafu's, and other symptoms, notably spotting/necrotic patches, from different locked-out nute's would have manifested way before this overall yellowing.... a flush now may strip away what little is there, and doom the plant,...

Hi Dr.'- Hmmm, some yellowing is perfectly normal in the later stages of flowering, but this is excessive; here's what I see from the pics, and tell me if I'm wrong: overall yellowing bottom to top, bottom being the worst (?).... pics can be deceiving on this, so you confirm this please; no spots, discolored/necrotic patches, right? BioBizz nutes are very mild, so I don't think you've over fertilized... there's no symptoms of that which I can see,... just the opposite, very likely, she hurting for N, this fits the symptoms best; you say feeding has been at half strength for Bloom, or both Grow and Bloom? (generally, blending is okay during the first couple weeks of blooming, but switch to full bloom after that; really, this depends entirely on the N-P-K numbers of what you're using)...let's see,.. grow 4-3-6, bloom 2-7-4...yup, really mild stuff, in a light soil mix too?.... I think the plants demands are exceeding what you're giving her, and at this stage of blooming, the demands are high! N is needed all the time, including during bloom, when the plant is building mass in the buds, N just doesn't get the emphasis that P and K do during this time....*** Now, not to be confusing, but rare Sulfur defc. looks a great deal like N defc., but the tell is, with S, the younger leaves yellow out first (S is immobile), from the base of the leaf forward.... N (mobile) defc. yellows lower leaves first, and from tips back... looking at a couple leaves closely, I doubt it's S defc., besides, bioBizz nutes are based on sugar beets(?), which should have enough native S in them,... *** So, normally N at this stage is a no-no, but like I said, this is excessive yellowing, far to early for it to be normal.... Feed her full strength grow and bloom mix, with a T/gal of molasses or even honey,... it'll take a few dyas so see results, so watch patiently...
...another possible thing to speed things along is a foliar spray of Grow, very precisely , on the fan leaves only, during lights on, but don't place them back in the direct light; pull them aside to dry slowly, to let the nutes get in while in solution,...foliar is the very fastest way into the plant, but during budding, it's risky if done wrong/sloppy, due to potential mold issues.... Again, this is a maybe thing, not necessary, but if you think you can be sniper-accurate with your spraying, go for it and follow the directions given... Oh yeah, a water spreader/wetting agent is critical for this, don't spray in this case without it! -if you want more details about this let me know, mate!

thanks for going into more detail, from what I seen this happend very quickly, basically I checked the day after feeding and the entire plant was yellow? I could not really tell if it's from the tips in or the base out but I have heard people talking about neut lock could this have happend? The plant seems to be growing new bus at the bottom of the plant now which looks green and healthy? Could it have stopped taking in water due to ph level and is now sacrificing the leaves? The buds are shooting out orangey brown pistols instead of white and the smell has changed and isn't pleasent?

I honestly believe it's the oh level now the more I think about it, I just don't understand how the bloom changed the level so much, I used half the recommended amount and I've waterd my plants with normal water left sitting 48 hours for 5 weeks with no ph lock so it has to have been the bloom if this is the case, I just hope there not doomed as I put a lot into this grow which is my first and I just Wana smoke some nice bud instead of rip off strains for extortionate prices
