Help with first grow, yellowing/dying during flowering stage

Indoor Growing Climate
1

Trying to correct this issue, it’s gone pretty far and nothing I’ve tied so far has worked.

PH was a little high (closer to 8, I am working it down)
I’ve tried to keep the soil moist, and I don’t add much nutrition (less than the directions on nutrients calls for) but I did add rabbit manure back when it was new and in growth stage. Manure from rabbit is high in nitrogen (too much nitrogen?)

I don’t think its heat burn (its happening low and high)

I can’t tell if its nute burn, I’ve tried watering without nutes to flush it a few times and it doesn’t seem to get better.

I definitely recommend you fill out a support ticket so we can get all the basic facts, plus a few photos would be helpful.

Just from what you said, your pH is extremely high; for soil it should be approximately 6.5. PH issues can cause nute lockouts, and all sorts of problems.

Regarding the rabbit manure: was it composted/aged/etc first?

If you really want to flush, you have to run a lot of water through. For instance, for a 3 gallon pot, you have to flush with 6-9gallons of pH’d h20.

I’m going to try to find you a support ticket.

First yes pH to hi way to hi… second if you are not feeding full nuts I suggest you do epically in flower she’s hungry. And the third thing I see is you need to let your soil dry out before watering if you keep your soil to wet it can cause root rot and other issues

Blueberry Autoflower

Soil In Pots, Hydroponic, Or Coco?

Mix of coco choir, soil, worm castings. In a bucket

System Type?

In a grow tent

Ph Of Runoff Or Solution In Reservoir?

I haven’t tested the runoff, but the water going in is on the higher side of neutral. the soil I tesetd was closer to 8ish andI did some PH down yesterday for that.

Doing a dynagrow its 2-12-2 I think.

Yes, a 4 inch pipe and carbon filter system (been makin a little more noise lately)

Rabbits are in same room, probably a little but not much co2.

I posted a support ticket up above. Just copy & paste it.

From those photos, this issue looks very far along. How high are your led’s from the tops of your plants? Looks like a combo of light burn & major deficiency/lock-out. Looks very similar to my first grows.

I think you need to flush with low pH’d water, asap, then feed them properly. That pH needs to be down fairly low for coco, so depending on your actual ratios, you really need to get that pH corrected. Your plants are starving b/c they cannot eat.

If your Ph was close to 8 then that’s your problem. That’s extremely high, so as soon as you get it down to a more reasonable 6.5 you’ll see some improvement. Right now there is nutrient lockout because of the high Ph.

They are almost done and looks more like Zinc or nutrient burn

possibly severe Potassium def more likely

since using

has lots of P low N and K the low N isn’t an issue it’s the K

So should I fix the PH first and then try the potassium ? Maybe add a little banana peel or cream of tartar powder for potassium

You should get your Ph under control first because that might take care of your other problem as well.

I was thinking nute burn when u saw pictures

update: the nutes i use are actually 2 12 6 not 2 12 2

And the water coming out of the bottom was closer to 8 ph as well, so I added more ph -

update: the pistols are turning reddish and the little clear things are turning more opaque. I guess its about ready for harvest. What is the trick in order to force a second grow of some of the plant while harvestin the buds?

In coco you need to run ph around 5.8 - 6.1
