severe yellow too early in flower

I am 32 days into flowering since sex showing and my plants are yellowing very badly and many leaves have straight up died from not only bottom but middle of plant. At first I started with only bloom nutes first 1.5 weeks, then got canna boost, flores, and pk 13/14 and have started using those. I slowly added flores but yellowing started to get bad so I have upped it. It also looks to have mg deficiency. I used a veg nute last watering and added pk 13/14 to up the ratio of that to N. I just watered again today with more nutes. I waited one day later then my normal water schedule which is why they are droppy. Is my yellowing happening too much? Should I keep upping nutes to full dosage now? I am at half and still having the problems. No signs of nute overdose with burnt tips. During veg this plant was picky as hell for nutes, not it can't seem to get enough. what are all of your opinions?

dude im having the same problem and im currently using Bio canna Flores pk 13/14 molasses, i gave her some magnesium recently. Im also using cannazym with pk 13/14 and flores.

Your problem is identical to mine. except mine are browning on some spots and crumpling apart. but other than that. I started noticing the early yellowing at around 30 or so days as well.

Shes at 6 weeks flowering now and almost completely yellow. im going to give her some veg nutes and see if that help any. Nothing i seem to do can fix it.

Ill show some pics in just a sec

I would take off all the yellow leaves off now. And if you have clones from them I would add Nitrogen once a week (12/12) for the first 6 weeks.

I prefer Amino Aid. It solves the problem.

add a quick dose of nitrogen(veg nutes) full strength asap...that should give her some green also use about 1 cup and a half of peroxide to help her take it in easier by giving the roots nitrogen filled micro-bubbles

I would advise agains't giving a Flowering Lady in soil peroxcide.
If it where Hydro, sure, but if you do that in soil you will kill all the good microrganisms that have been living and breeding in that soil for months.

I am also having the same problem. I am about a week into flower and all of my new growth is coming in yellow, but it seems to turn green after a day or so. None of the other leafs are really damaged. I use ebb and flow and flood into hydroton. I flood 4 times a day. i flood twice 10min. then 15 then 10 again an hour b4 bedtime, 3 hrs apart each time. i am using a 150watt hps and 3 cfl's. The light is prob about 10in. away. I have a fan in the closet and an exaust fan blowing out. i dont have any air coming in except when i open the door. I sometimes leave the door open, on warmer days. The average temp. is about 75-85, mostly in the 80's. MY humidity, between 40-50%. Everything seemed 2 b going great until recently. i dont have an EC meter or anything like that... so i just make sure i dont over do it and i change my res weekly. My PH is always around 5.8-6.4. not exactly sure because i have a cheap fish tank test kit. I try 2 adjust the PH with nutes... but i dont add very much at all. I use Flora Nova and my plant is a high yielding sativa.. not sure the strain. but its good and its second generation hydro fem. seed. I Just dont understand how the new groth can come in yellow then turn green. its not all of the new growth tho. just some of the branch tips... i need some help too. Any thoughts or ideas? I can post some pics 2morrow. and im gonna start my own thread using this, so check that out.

hey thanks all for the advice. I had tried using veg nutes for the higher N, but I was also adding a litle pk 13/14 to it to try and get the higher ration, especially since my plants seem to be loving it and the stems are still slightly purple at some points leading me to believe it could use a little more P/K. Do you guys think it would be better to use some veg nutes once in a while or just ues the canna flores nutes more often? Ratio is 2-4-4. That seems like it would overall help my situation with not enough p/k and N. lol, maybe this was much more simple then I made it. Only good thing the veg nutes have is the micronutes in it, which my canna flores does not at all. Fun thing is, I can tell my plants are at that point of "blowing uP" in size again. fun times!

Could very well have root aphids! Have you noticed any "fungus gnats"? Take a close look because they could be root aphids...

They live in you soil, eat your roots, and kill your plants. Usually the symptoms show up as an incurable nitrogen deficiency early on in flower becoming much worse by about day 30 of flowering. Search root aphids on ICMag...
