Hey guys i really cant get my head round this now i though i fed to much at first and layed off the nutrients for a week and then used 1mill of grow and 2mill of bloom per litre. The soil meant to only had two weeks of food i had gnats from a cheap compost in veg but soon as i flip to flower i cant stop the yellowing everything going to shit now.
I feel alot of work going down the drain now. ive never had plants yellow and leafs die so fast thinking not getting any bud from this at the rate the leafs are falling everything what can go wrong has thinking could be overfed now underfed too much water gnats which have nearly cleared up now one the whole plant pretty much yellow just green tops. Any idea whats going on. IMG_1344.jpegIMG_1342.jpegIMG_1341.jpeg

What’s your feed? She looks pretty standard hungry flowering plant to me. Just keep up food and add something with magnesium if it’s not in your feed, and add alittle extra n to the one hats fading faster than the rest.

Whenever I have had this happen, it was always from not feeding grow enough the first part of flowering. I feed grow regiment for two weeks or so after I change lights and then transition into flower regiment. I do not know if that's going on with yours, but that's my experience. I think you will be just fine as I have had much much worse and still harvested a lot of good bud. I am anxious to see what more experienced growers have to say because yours is a common problem.

Thanks for the fast reply the first week i feed 2mill grow and 2mill bloom but i was seeing brunt tips and as i was useing a weaker grow nutrient on my last grow, It should of been 1mill and though this may be the problem as my old grows i never upped it over 1mill of this nutrient brand but i was useing different soil back then too. My last grow i had plant magic nutrients and was able to add more as its weaker then the biobizz grow but my first feed i totally forgot why i thinking i overfed so gave just water last few waterings then feed 1mill grow 2mill bloom removed most of the yellow leaves left it 3 days checked now and looking more yellow. Hope this makes sense. I live in a hard water area too so haven't added magnesium this grow maybe these need more.

So you’re using bio bizz now? I like there line but it’s extremely low in fertility ime. Your burnt tips probably were from your soil mix not the nutrient line being organic based and very low npk. I’d hit them hard with grow and bloom and some epsom salts cause your magnesium def is spreading and will cause more lockout as time goes on. Or if you want to buy a product plenty of “sweeteners” out there that consist of magnesium sulfate. Or some nutrients likes have it. I like one part pure blend pro from botsnixare. It has Calcium and magnesium plus good ration npk for soil grows which need a bit more

I have a bottle of plant magic magnesium and calcium which i will add. Yeah i though bio bizz grow was strong well compared to plant magic grow bottle even opening it my god it stinks why i changed to plant magic but knew could add more and now gone back to biobizz as all shop had at the time. hoping this is the issue and will up the feed thanks for the help.

What are your temperatures? Doesn't look like a cal-mag issue. Aren't these girls supposed to be getting some phosphorous and potasium in flower? Could be a lockout of some sort. What is your Ph? I don't see burnt tips. I looked up some plant magic, and they all have lower PK than Nitrogen. It looks like a nitrogen def, but in flower? I'm thinking you might want to bump up your phosphorous and potasium. Maybe a banana tea with some bone meal would help. Since you're oganic, do you have some worms in the soil? Maybe some EWC in that tea too.

Ive been useing the bloom too. the temperature never goes higher then 27 and not lower then 19 degrees. i dont ph my soil years back i tryed and caused more problems and only bugs that ive had a probelm with till this grow. the soil im using saids 6.5 ph on the bag. All i use is bottle feed my last grow was all plant magic grow and bloom and a bit of enzyme from the smell of the grow bottle i think all that is in it must be worm shit going have to change it when i can the smell is unbearable know why i stopped using it now. Just mixed a watering can up of grow and bloom 2mill grow 3mill bloom and 1mill of mag cal.

Like I said, the cal-mag proly won't hurt, but there is something causing the yellowing. You're not getting any burnt tips, so I'm thinking your plants are pulling nutes out of your leaves. Its because they cannot get it from feeding. Do you test your runoff? I hope you get some good results from bumping up your bloom nutes. Keep up the good work.
