:jaw: Can anyone tell me what's wrong? This is a dinafem critical jack at 6 weeks old, it was looking great and very healthy until the last few days it has turned almost completely yellow and there are some dark orange pistols coming from the bud, the stems are going purple and it doesn't seem to be taking water. It's in a 80 x 120 tent with a 400hps biobizz light mix and all mix soil and using bio grow and bloom, this seemed to happen after I give it two feeds 3 days apart with about half the recommended amount of bio bloom? Could this be the problem?

Thanks, temperatures around 25 degrees Celsius sometimes a bit either side. I give it a mix of grow and bloom in last two feeds, I haven't being checking ph levels I leave my water out with the lid off for 48 hours and everything's been fine until now? The new growth at the bottom of the plant looks healthy and green but as you can see the majority of the plant is completely yellow and terrible looking, if this is due to the feed of nutrients how can I get it to recover in the last four weeks?
 
Can anyone help I don't think I have much time to save it?
 
Does no one on this autoflower site know what this problem is with an autoflower plant? Lol 21 views and no one has a clue? Serious?
 
well the best info I got for ya man imo is its prolly PH off a lil so its not using all of what your giving her making for a toxic environment.C02 and PH are the bes places I can give you to start imo that may help.sorry Im an organics guy.little experiance with nute stuffs mostly.I tried man but I dunno.LOL!
 
I have just ordered a ph pen thanks for your reply I'm new so any help is great? Do you think it will die? What would you do next? Biobizz is supposed to be organic? Would I be better using no nuts? What should I aim for ph wise? And finally will that plant affect others if I dnt remove it? Thanks again eyesonfire
 
ya Eek had it right man,info is key when your running nutes man.PH,temps C02 all the basics man.in and out PH so you know exactly where your heading and can steer your grow the way YOU want.no have it push ya round.LOL!Be good dude.invest in a decent Pen too.50 Bucks US is a decen for a Hanna or some such reputable brand man.L8r.

you need to hit the 24/7 help thread.Ive never used Biobizz n things.TThere is a TON of help just sitting there with people who eat nutes for beakfast man.LOL!
 
No probs thanks again I'll get back to ya in a week with any changes, think I'll just stay away from nutes from now on lol
 
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!
