What should i feed? Plant slowly dying

Hey everyone i have a problem with my blueberry plant shes yellowing.
About 50 days old, compost medium, water every other day or every 3 days depending when its dry.. What should i start feeding this bitch?
This is contrasted to a nyc diesel plant that is the same age grown under the exact same conditions and looks fine...
1st pic is the hurtin blueberry , second nycd ( i have a feeling shell need feed too soon)

you should transplant it........

woody just curious why you think that. could you explain your thought process a little more please?

give it a dose of food at half strenth and go from there, transplanting is a nothing to do with this problem

if you've just been giving it water then this looks like a simple N deficiency to me. you might want to check your water and runoff pH just to make sure it's not a lockout issue...also how much longer do you plan on vegging these out? that pot size should be fine if you're flowering soon, but i'd definitely transplant into a least a 3 gallon if you want these to get huge

What kind of food? this is where im stuck... Its already living in high N soil ( blood meal enriched )
So does it want more P and K?

what NPK ratio?

really??? Pick a brand and use their recommended ratio's to start.

Ok well just asking because i intended for this grow to be organic, but the only ferts available here are chemical. So i have no idea and dont wanna fuck up my plant. The brands are for flowers and vegetables it doenst say anything about marijuana on the labels haha

Frizzle,
Please don't feed it. Maybe a transplant is indicated but that only accelerated the problem. Looking at the extremely dark green leaf color on both your plants...I would say that you have been overfeeding them. The fact that you have multiple deficiency symptoms on the blueberry hints at a lockout. I see one leaf showing Mg deficiency, one with N deficiency and that peripheral yellowing is usually from a K deficiency. And of course, it's extremely unlikely that your Blueberry is suffering from all three of those deficiencies. Oh, and isn't there also a small leaf back there with a little tip burn? I rest my case.

Growkid suggested testing runoff water. Check PPM also if you have that capability. High ppm and low ph is what I'd expect.

1 day before transplant. same plant after transplant 1 week later. TRANSPLANT IT!. On my first grow but your plant looks i eerily familiar to how mine looked before i transplanted. When idid, the yellowing stopped.

Mannnnnnnnnnnn shit is so unavailable here right now, can you do it with pet store ph strips?

Nice, looks like you still got some yellow down below but it did help growth..

Ya Frizzle, that will give you an idea of ph. I used to use them. If they have the drop system, I understand they are a bit more accurate. More to the point...does my post make sense to you? If adding more nutes makes things worse...well that's a hint. Plus look at some ganja pictures and then look at your plants. That super dark green is a classic symptom of overfeeding.
Good luck,
JD

Yes . Makes total sense , if ph is off it cant absorb anything regardless of how prevalent it is.
Ill try and figure out a method with fish store strips but idk about accuracy like you said....
Thanks !

Your welcome Frizzle,
I just want to point something out. Overfeeding causes an accumulation of nutrient salts in the soil. And this is where I bump into the limit of my understanding. I know the toxic salts lower ph but I'm not really sure if the salts themselves cause the lockout or if it's totally the ph drop. The ph will give you a pretty good clue, but even if the ph is normal...without testing PPM of runoff, you can't be totally sure.

So I would err on the side of caution, and assume lockout from overfeeding. Just use ph corrected water until things start to improve.

Yellowing from a plant needing nutrients looks totally different then what's going on with you. It's just an overall fading (yellowing) of leaves starting at the bottom leaf tips. This is the plant moving mobile N to new shoots. When that starts happening, then it's safe to start feeding again. At that point, your plant should have returned to a more normal medium green coloration also.
Good luck,
JD

Thats kinda what i was thinking : (drawing n from leaves)

Thank you for your time

your plant would look better in a couple days if you transplanted into a good organic soil

I agree with woody and JD.

xplant...and stop feeding for a while. Water only imo.
