Leaves yellowing too fast in flower?

Roots have been mentioned once or twice, and I fully believe they are your problem. I've ran into this issue before, it makes you think it's a nutrient lockout of some type or whatever...and it is a nutrient problem indeed, but it's because your roots are probably trashed. Since the roots can't property uptake nutrients, the plant is effectively cannibalizing itself to get the mass nutes it needs to build the big buds you want. I almost guarantee that if you uproot that sucker right now (which would be insane...don't do it lol) you would see the roots would resemble an elephants foot (sorta). There would be a fat mass below the base of the stem with spindly shitty looking roots coming off of the rotted nasty fat root foot. It'll still make buds, but expect about half the yield you would have gotten if your roots were healthy. Number one cause of this condition is overwatering and nothing else. Not saying this is 100% what's happening here, but I've experienced this and that was indeed the culprit. I attached a pic of a past plant that had this issue. See how shitty and sad it Is? This was 7 weeks into flower, and it pretty much looked like that since week 4. After harvesting, I pulled it to see if my assumption about the roots was correct, and lo and behold, when I pulled it, it looked like a ginseng root....no bueno.

With all due respect unhealthy roots definitely can cause problems that resemble PH issues but your plant looks nothing like his health wise. That’s a clearly sickly and struggling plant. His is yellowing but does not look sickly like yours does. Over watering can’t be corrected in flower and doesn’t look like his plants, under watering would resemble his plants more TBH let your plants wilt and they will look similar but I still think he switched to bloom mutes to early I have used FF OCEAN FOREST a lot and 7.0 PH SHOULDNT cause these problems. ocea. Forest has enough veg mutes to last about 30 days, if you switch to bloom you need to stick with the veg mutes for at least the first week leading into stretch, but it all depends on strain. Some strains wo t yellow no matter how much u flush them. It’s all trial and error.

I see how it seemed I was trying to compare mine to his, but I was simply showing what shitty roots can do. I got that plant when it was already 2 months old from a buddy who gave up on it and I tried saving her to no avail. Not claiming to be an expert here but I'm sticking to my crap roots theory. I think it's at a bare minimum a strong contributing factor.

Hey man yes thanks and it’s funny that you mention underwatering twice in veg I wasnt able to make it home in time and my plants were wilted and then it also happend once in flower a week and a half ago the plants were wilted pretty bad but I watered her she came back to life but I’m sure that causes stress correct?

PH could be a tad lower in soil between 6.5 or 6.8 I don’t think 7 would be causing nute lock out but it’s possible. Is this a strain you have run before or first time?

I have not run this strain before but it’s supposed to be really good genetics it’s from Ethos genetics it’s called Rainmaker supposed to be a heavy yeilder

I'm gonna guess you have been using both of those bloom nutes since flip to 12/12? This usually happens when you feed heavy bloom feed too early. The conditions are top to bottom so it isnt hungry and its not N tox.

That’s what I was thinking. Too much P and K causing lockout.

Bottom line. These 2 guys are right!

To much P, to early!

Low pH allows for more N uptake. High allows more P.
Even with a low pH feed solution. The over use of P will cause this problem!

Using an active living bio solution - like Mammoth P is only making the problem worse!

When using many bottled nutrient lines.....Run the veg for the first 2 weeks after the flip and then mix the veg and bloom 1:1 for the 3rd week. Full on, 100% bloom after that.

Bloom "boosters" are not really needed to find great success!

Finding the right "balance" ratio is the key...

Good luck

Thanks man I wa using recharge and mammoth p together that had to be it because I got it for Xmas and don’t use it till 1st week of flower
 
I have a question Since I have been using the old Fox Farm crappy nutes I went and bought new nutes. blue planet nutrients elite 3 part I’ve heard a lot of great things about this company so I’m deciding to try them out I just have a question am I able to use this with my Foxfarm ocean for soil and if I am do I cut the dosage in half? I also got cal mag from the same company it hasn’t come in yet. Hoping this will Mix well with my soil. Here soMe pics of the nutes

Also and updated pic on the plant I ended up cutting out most of the dead leaves I left some that look like they still have some life

I used 100% Fox Farm Ocean Forest soil since seed. I've used 5ml/gal Big Bloom since week 2.5 from seed every other feeding. In conjunction with that I used their vegetative nutrient Grow Big approaching 10ml/gal in week 4-5 through week 6-7. I started using Tiger Bloom slowly at first 5ml/gal during the veg to flower transition when switching to 12/12. Starting week 3 of flower I have been feeding 10ml/gal Tiger Bloom, 10ml/gal Grow Big, 5ml/gal Grow Big, 2ml/gal Cal-Mag, 1tsp/gal Blackstrap Molasses.

With all that said, seems like unless your plants are super sensitive, I dont' think there is anything related to using too much nutrient.

Feel free to look at my thread in the Indoor category.

Yea man I think that it def was the mammoth p that did it cause I fed it too much for sure.

Think these blue planet nutes are good to use and should I cut dosage in half since I’m using fox farms?

I think you should switch to organics since you’re already in organic soil, personally, but I wouldn’t cut them in half, just don’t feed for a bit. Like a week or two. Unless it starts showing clear deficiencies. But, yeah, leave it alone to work itself out. And definitely wait to use the Mammoth P for a few weeks.

Exactly man I was even thinking of not feeding her and letting her ride out since she’s on day 38 already what do you think?

There you go man anytime the plant wilts the leaves yellow, it can correct itself in veg but not In Flower only thing it’ll hurt is the yield but you should be fine.

The yellowing is 100 percent from letting it wilt. Keep feeding nutrients like normal anytime u let your plant dry out to bad it’ll happen.

I like the NPK balance of your new nutrients!

The N maybe a bit high for some strains in Veg and Bloom. No biggie, just use less if you see an N overage begin.

I wouldn't add Mam P to that in bloom either... Home made AACT works just like Mam P and is stupidly cheaper to make! Still, maybe and I mean maybe! Use it once at week 4...

With those. I would use only HALF the bloom and Micro they say in vegging!!! I would do the switch to full bloom at the flip.....BUT! Drop the "Grow" and only use the Micro & Bloom formula and amend with a 1.5% Mg sulfate supplement. Watch the N for overage in bloom.

You can make that Mg sulfate supplement at home with Epsom salt and DARK BROWN sugar.
8 TBL Epsom
1.5 tsp DB sugar
1 Gallon of RO water.

Mix (shake to dissolve) till dissolved and use at 10 ml per gallon of feed solution.
The Mg sulfate mix will cost you less then a buck a gallon to make! The same shit in a grow shop will cost $65 a gallon!
pH the nutrient solution to 6.7 and feed.

STOP use of the Mg supplement at 2 weeks to finish!

Try this! I know you'll be very happy with the results!

I add epsom to my water but what does the brown sugar do? Just curious

The brown sugar adds carbs to the soil. This feeds the living bio's to be more active. More active bio's, make for more available nutrition to the plant.
Increases uptake by increased availability.

The Brown part, adds micro's.....Good stuff....

Mg sulfate also increases trich and trep production....

I agree with this, rings the K.I.S.S. bell in my head.

I would like to add, i'm only using Fox Farm trio at like 60% recommended doses on bottle. My next round I might wait till the plant actually shows me it needs nutrients. Using organic soils though everything is delayed and buffered, so burn is slower to show and takes way longer to correct. Also I don't flush water, I only water till it starts coming out the bottom, combined with watering slowly it seems to work for me.
