Indoor yellowing fast biotabs in coco under led and hps

[Trichome farmer]

so we have some yellowing going on pretty sure its cal mag related due to the light being so close its only on the lowers of the big bubba so far and has progressed pretty quick in a day or two what should i do i did pre charge the coco with 50-60g of plagron calcium kick maybe a top feed again no experiance with this kinda thing im a bottled nutes guy @Ryker604_BT @Hippy_BiotabsF70 and anyone else who may have some ideas please im all ears

apart from these few all other leafs are looking nice and green with a slight tip burn nothing major

a few other details that might be needed I ADDED 50-60G OF PLAGRON CALCIUM KICK TO THE COCO at the start and temps 28-32c humidity 55-75% 1.5l of straight water a day she will be getting her second dose of PK tea today

Sorry for being late dude, I'll answer in this thread .

For starters, how old are the plants and how much light are they getting (you run both the TELOS and HPS, or?)?
Haven't used Calcium Kick from Plagron and as Hippy said in the other thread, shouldn't CalMg problems start from the top? I'm not sure dude but the yellowing of a lower fan leaf could be nothing, is it spreading fast? Are many leaves hit or just one, two? Only the Bubba Kush?

P.S. My grows are finished but real life has been really hectic and I didn't have the time for AFN. I'm gonna finish them soon and I can just say that I'm really satisfied with Florganics . I'm back near the Mediterranean again, so sending positive and sunny vibes to you bro :

yeh mate telos and hps running together the telos does the full 12/12 and hps is on for 10 hrs on 400w plants are on about day 30 a few of the bottom leafs are doing it and its moving pretty quick id almost have said it was just cannibalization but its moving very quick and just on the bubba the crispy girl is still fooked dont think she will make it and the zkittles seems fine so far

-- mate I'm in the dark here, i need info about your nutes... I see you called Hippy Biotabs, are your running their system? Always always always, an in-pot pH check is where you start to determine if it's a lockout issue, or a simple lack-of,.... that color fade is pretty generic, early on,.. could be Mg (and coco does hog that some), early P defc. can start like that,.. off pH in general,... Biotabs/organic doesn't "self-buffer" in the pot,... any inoculants going in? Orgatrex, Boom Boom foliars..?

yes im sorry full biotabs line up going in . how does one measure ph without a probe . what do you mean biotabs dosnt self buffer in the pot ? .bo boom boom spray since veg and one feeding of bactrex and orgatrex at week 3 and two feeding of bio pk tea
i think thats everything answered

...well, you're jammed up on the measuring w/o a pH probe since you can't do the usual pH and EC/TDS reading of run-off when using coco,.. Get an Accurate 8 soil pH probe-
... what I mean is that no matter what the system,. organic or not, it's possible for off-pH conditions to develop in-pot, it's just less likely with organics,... the key there is a vital, abundant diverse soil herd,...... that said, in soil, pH'ing my 170ppm water to 6.5, I had zero pH issues with Biotabs,... so more likely is that this is a simple lack of,.. treat foliar to bypass any questionable issues with the coco,.. it might be that the coco is binding too much of the Ca and Mg still, keeping it from the plant, or at least enough to not meet demands...
.... looking at the nice size of them, and the stage, I'm leaning more toward early P defc.,... now i will say that my Tabs were largely consumed about this time, and I had to start feeding bloom nutes,.. I did use PK tea, but also Roots HPK (liquid bat poo basically .. 0-4-3) and even light hits of high P-K bloom boosters,.. a little synthetic nutes isn't going to queer the organic deal at all, trust me,...remember, it's all the same to the plant! I used Cha-Ching for that, and Elite Resinator for finish (higher K, lower P),... this all made for fine fine buds!
:smoking: I'm looking forward to seeing how these new DP girls turn out! Skelly has a Bubba Isle going,... I've had Z'kittles locally, and it was superb, so candy-rich terp'-bomby,... betting the LZ will be like lemon Pez candy!:drool:
