Lockout in middle of flower?

So I’m in the middle of flower and a few of my plants have started extreme yellowing like they are in dire need of nitrogen. I don’t think they should be yellowing this rapidly at this state so I reamended with 4-4-4 and added seabird guano at 0-11-0 but that’ll take at least a week or two to start breaking down for use.

I have some 5-1-1 fish fert I wanted to give a shot at using. Should I try using that for a quick N boost?

or I’m working if it could be PH. I’m working in a coco/peat mix of Roots formula 707 mixed with added perlite, ewc and amendments.6829B57B-7C82-4ECD-AB8E-5C4DA12220DC.jpeg

Do you know or have any way to test your ph? If it's off enough your probably going to have uptake issues no matter what you try to give her

I'm a long time reader first time grower in rdwc which is obviously different. Going from experience with corn in fields, I wonder if over watering may have removed or is preventing up take of n? Trying to help. My questions might get someone smarter to chime in

I did do an experiment which could’ve had some play in this. So most of my plants I just feed organic amendments. But I was short on food higher in p and K for flower and due to quarantine all I could find is some miracle grow organic pellets that had higher p and k but also had higher N and were supposed to feed for 4-6 weeks which wasn’t an issue.

i decided that I didn’t want to put this directly In my soil tho so I put a couple tbps of the pellets into some EWC and made a tea to feed. But then I was like let me try an experiment and I picked about 3 out of 9 plants to put the pellets directly into the topsoil and water plain water for the rest of the grow and see the results and compare.

well they were all doing fine at first but the ones where I put the direct pellets in the soil seem to be the main ones kind of going through this. But I fear it’s nothing I can do now to fix it other that just keep watering plain PHed water and ride it out. I’m just glad I finally got some seabird guano to combine with my 4-4–4.

I'm pretty sure the mg is a no no. Any time I tried it with seedlings it went bad, but you might be able to water them heavy or flush them to get it most of it out

its different with organic amendments because they aren’t solvable salts that can typically be flushed out. Usually they break down into the soil over time so there’s no getting it out. They may be fine riding it out tho.

Ahh did not know that, only other thing I can think would be repot if you could do so without inducing too much stress?? More dirt less nutrients.

I agree with your initial suggestion that it's a lack of N, especially how it working it's way up from the bottom leaves. I don't know why you would have hit them with seabird guano when you thought it was N. Too much P can cause lockouts with a number of minerals, which may be part of the problem now. I think patience is key, and like you said you just need to ride it out. Soil buffers so much. Problems don't show up immediately and they don't clear up immediately either. I think you may be doing too much all at once to try and fix it. Good luck!

The seabird guano wasn’t for the N. The seabird guano was cuz they were slightly P def at first but I chopped those leaves off because I knew what it was because I didn’t have any flower nutes at first and I’ve already error corrected that. Then as soon as I went to correct the P the N issue showed up. But I just put the guano in yesterday so it definitely can’t be that causing it because it hasn’t broken down yet

Hey army, you might try reposting this in the organic section to see if someone there can give you better advice. I know you can't be the first with this issue and believe you might find someone there with a possible fix. I guess our grows not near as similar as I had imagined, just a thought, I'm watching and routing for ya! No one wants to lose any of their babies

I'd just give pH'd water for a week. Dumping more stuff on something that has issues from improper feeding isn't going to fix anything. You'll just be chasing one thing to the next. Slow down and let the plant settle down. But at this stage of flower you likely won't be able to stop the yellowing. Best thing you can do is slow the damage. Plain water is your friend right now.

So many people don't realize that their deficiencies are not from a lack of nutrients but too much of something and the best thing to do is nothing. Adding more just adds more problems and it keeps going on like a merry go round.

I did have P defiency. Adding the seabird guano didn’t cause this problem, this problem was going to happen anyways. Seabird guano takes weeks to break down

I think not.
Nitrogen deficiency shows as yellow leaves at the bottom, and green leaves at the top.
The plant eats it's lower leaves to provide nitrogen for the top leaves.

Yeah I think it’s MG like someone else said. I don’t use cal mag and it’s possibly my soil has run its course In it.
