Phosphorus deficiency?

Project Ponics · Aug 16, 2018

Is this a phosphorus deficiency? It’s spreading up the plant so I need to take care of it since I still have a while to go.

I received my order of Bud Explosion in the mail today as a PK boost, to go along with the MegaCrop I have been feeding them. I just fed them 6g if MC and 1.2g of BE. It was about 1150 ppm total, when I’ve been giving them a solo 6g of MC which is roughly 850 ppm? Either way, Hopefully it will stop the problem.

What do y’all think?

I'm in hydro and had identical problem. Mine was attributed to a PH imbalance which caused lockout of either phosphorus and/or nitrogen deficiency. Got PH dialed in, added a good NPK dose and has dramatically improved.

Mykos or any brand mycchorizae . Main function we care about with cannabis is attachment to roots for uptake of phosphorus. The main use for mycchorizae.

Ph fluctuations, according to plant doctor

I was going to get some Great White, would that help?

I did a soil slurry test and it was 6.3 ph but only read around 600 ppm.

I checked my waste from my coco plant and that all seem stable as well. 5.9 and 1100 ppm

Great White is fine. Expensive but it works.

Any other good brand you’d recommend? I don’t think it’s a ph issue though? At least not after doing slurry tests/checking everything else. Not certain though.

The rest of the plant doesn't look like it has pH issues . In my opinion . Xtreme Gardening brand Mykos is cheaper and works great.

I’ll check it out thanks, aren’t you suppose to use it before transplanting pots of when planting a seedling? Or do I toss it on top of the coco/soil?

I mix in my medium when transplanting but i also use it top dressing. The wettable powder type. Sprinkle it on before you feed and it will find its way to the roots.

One word Recharge (benificial/microbe innoculent). The stuff brings back plants under stress (in your case deficiency) but if your feeding regimen, environment, etc., are not in check the problem will ALWAYS come back. Peace.

Hi dude looks similar to my problem i had but soon as i flipped em and added bud blaster was as if a new leaf had turned... literally lol some pics from before...

I'd say try add sumin with bit more phosphorus but only in a tiny amount see if it gets any better?

Do you know if mykos affects ph at all?

No, mycos do not affect ph, if anything, they help keep things in check. They help gather food and bring it to the roots. As for your issue, the plant is definitely showing phosphorus lacking. Ph at 6.3 is good, so other things looking good, add extra phosphorus until problem stops spreading.
As for budswiser, you have other issues than phosphorus! Namely what looks to be a calcium deficiency, and possibly iron, zinc and or sulfur.

Yeah I keep getting more and more problems. The soil seems to be getting it worse. I’m feeding them 1/2 to a full gallon of nutes a day!!! And I’m giving them 6g MegaCrop and 2g Bud Explosion for PK. And they’re drying out the pots crazy fast, especially the coco. I just overfed them at 1250 ppm with both Mc and be mixed in a gallon. Last feeding was about 1100 ppm and still showing they want more...

Just an update... all my plants are lively as they were the first time now... could not flipping them in time cause issues? As soon as i swapped to a 12.12 schedule and fed them budblaster (blooming nutes) they reached for the sky bright green leaves... all topped and fimming techniques worked and they've started blooming!

It seems to be true tho..less is more with these left them to decide wether it was a defficiency or overfeeding ... decided defficiency and threw the bud bluster at em!

Will post few pics later... now i have an led question or should i start a new like thread or summin??
