Small leaves near buds yellow

[roasthawg]

Hi all... I'm getting deficencies in many of my plants, it shows up as yellowing of the smaller leaves near the buds early in the budset (end of wk 2). The tips of these leaves stay green but the bottom portion yellows out.

I'm in rockwool feeding at 1.5 to 1.6 ec. 145ppm n, 40ppm p, 152ppm, 126ppm ca, 46ppm mg. Getting these numbers using gh flora 3 part. I've been keeping the ph at 5.6 which leads me to believe this is a possible ca issue that might be solved by upping the ph to 5.8?

Here's a pic... very tough to see as the light is on. Strain is the White.

Take photos with your lights off, you might have duds

Not duds as I've run the strain a bunch and have a lot of the same strain not deficient. I'll get better pics in the morning.

if you look in Joe Freshs thread in the infirmary it had that the Magnesium can lock out when its under 5.8 ph..ck out his thread...it may be the problem...DJXX

Could definitely be mag too... imo could be either ca, mg, or p. Not sure which... thinking I'll try raising the ph to 5.8 and see if that helps at all.

i went up to 6.0 cause 5.8 was giving me some issues...good luck..DJXX

Those don't look very frosted for being the white, and only 1 plant is doing this? All of them are the White ?

The ones that don't develop any deficencies get super frosty... I'll upload some pics tomorrow. They are cuts from dark heart nursery in oakland... super legit. My last batch tested at 26% thc. They are very prone to this deficency and my current run is showing more deficent plants than normal. Need to get this figured out as I love running this strain... plus some other strains will develop this deficency in my garden from time to time. It's a definite issue. Hoping it's the ph at 5.6... I've got coco plants going with the same nute mix but at 5.8 and none of these deficiencies right now.

Bro get those pics, I see the signs of dudding

 

[roasthawg]

here's a few more pics... so tough to get any good ones with my phone. first shot is deficient plant in wk3, second pic is healthy plant in wk 3. last two pics are healthy plant in wk 8

here's one more pic of deficient plant with lights off... makes it look way worse than it looks in reality though.

Those are duds buddy.... bet 100% and some on it

"White Flagging" from Stem Nematodes

Not duds as others grow these cuts without incidence. Just wondering what the deficiency is? Phosphorus, Ca, or Mg?? Symptoms occur with the small leaves nearest the buds. The tips of the leaves stay dark green but the rest of the leaf goes very lime green. Plant vigor is shot and very little frost is produced.

Bro, those are symptoms of DUDS.... it can be just a branch... just one flower...the whole plant... just a few...the whole tray...etc... the fact you have the "White" clone and its not producing frost and those lime green leaves... all indicators of DUD...

No reason all the same genetics in the same tray being fed the same thing... have different outcomes...unless the plant is tainted... go check out the DUD thread from the first page... Ive posted pics of my own genetics doing the exact same thing...

Hope not... I'm adjusting my feeding schedule to include more phosphorus and a slightly higher ec in general. I'll report back if that solves the issue.

Roasthawg, there is nothing wrong with your P levels. They were fine where they were. From appearances, I would lean towards a Micronutrient deficiency, particulary Fe, as it will cause yellowing of new growth. Calculate the ppm levels of your micronutrients and post them here if you can. That may help narrow your problem down some.

Oh, and definitely view the videos in my signature.

Yep. From the broads you don't know you have



Keep blindly adjusting the nutes if you want

Your vendor probably knows but won't talk. The #1 way to sabotage gardens is by selling fire cuts that are resistant to this stuff because then the grower is highly likely to let em build till all of a sudden all they pull is fancy looking hemp.

You can still make it though. I harvest 20% with broads pervasive, 25-30% with broads at low levels. Though, no over the counter stuff will do it. No one would sell the juice I manufacture because it makes fire easy peasy 123zy

Dave above, Fe deficiency is part of the broad diagnosis

What do you do to prevent stem nematodes?

would this "deficiency" happen to only occur on the tallest buds right near the center of the light?

cuz i don't see any deficiency here, even with the hps pic you posted in the first shot looks like a clear cut case of light bleaching.


but could be like trolls or goblins or some shit. try some of that magical spray from the shop in town.
