    While it appears to be growing fine two f my plants are showing new growth to have a tinge of yellowing. Went from Jiffy pellets to solo cups to peat pots.. Yesterday I tried to give a very very little dose of nuts micro and grow at a very small dose within minutes it seemed like the yellow was turning back to healthy green throughout the night. This am however the yellowing started again. Ive done a throughout water early in the AM yesterday which didnt have any notes at all, then when i saw that yellowing in the evening i watered it a very little tiny amount with notes in it..

    There appears to be a nute deficiency, but now if i do a normal watered ill b e overwatering the seedlings

    PH 5.5
    Promix BX with 20% Sheep Manure.

    Advanced nutrients micro and grow small dose seemed to resolve the yellowing

    Should I let it dry out in a few days before giving nuts or go for another watering? I think ill risk drowning the seedlings if i water P.S. I water about “3 shot glasses of water” worth. Here is a pic of growth and yellowing.

    Can you try and take a picture in normal lighting please. It's hard to see with the purple.

    Hmm...they almost look too dark green to me which would indicate a bit too much N, perhaps. They really should not need much, if any, food quite yet. Maybe someone else can chime in. How many days ago did you start your seeds?

    New growth always comes in a lighter colour green but shouldn't be yellow, they look fine from pics

    Starting with the biggest plant,

    Aug3 seed cracked AM biggest plant
    Aug3 seed cracked PM mid size plant
    Aug4 seed cracked AM smallest plant

    A day later they all sprouted in same order 24hrs later.

    I oddly cant find this problem early on online like mine I only see this problem when first few modes have grown already and people lead to ph, nutes etc..

    As I mentioned I tested very little nute very little spritz of water and it almost resolved instantly maybe 20 mins later.

    I agree the plants seem dark green to the eye here as well except for the center being on the yellow tinge.

    They dont seem to be stunted. I compared pics from 3 days ago and they almost doubled in size.

    The main biggest plant the stem is really shaping up its double the size of the other 2.

    That's what I thought since the ends of them appear to be healthy it's just the center part of it is yellow. I'll keep an eye on it

    Sulfur deficiency . Are you giving Micros with sulfur? Iron deficiency is possible too. Usually go together .

    Shouldn't your PH be a little higher for dirt? Is the 5.5 PH you listed for your soil or the nutrient mix before you pour it on?

    It’s 5.5 after nutes / 6.5 regular water sorry about the typo.

    It’s promix it’s mostly peatmoss and perlite not exactly soil although I did add sheep manure.

    As for the other post, my nutes test was using micro and grow together fraction of seedling dose but that was only a test I think it maybe too early to give it a full water with nutes in it but as mentioned if I would rewater with nutes now I’d probably be overwatering it

    Hopefully it can survive 3 days TIL next watering and I will add very little nutes.

    Other then sheep manure there’s really no nutrients in this promix

    It does not look bad by any means, I think it should survive three days haha.
    It will feed off the sucker leave until they turn yellow. Don't sweat it too much until then. Once they start to yellow hit with with like 100ppm of the micro and grow. Work your way up from there. 100ppm is something like 1/2 or 1/4 the seedling dose IIRC.
    You should be using the bloom too I think. Someone correct me if I am wrong.

    Based on what I read about the Lucas formula you can get away with using micro and bloom, but I am not sure about micro and grow.

    Bump your ph up to 5.8 feedings, few nutes are not available below 5.5, later in flower bump it up to 6.0

    Theres also no harm in bringing it up higher than that. I like to fluctuate my PH between 5.8 and 6.5. Different nutes are consumed at different PH levels so it's something to consider. I like to roller coaster my PH like a sine wave. Just my 2 cents.

    That's the way to go helps the uptake of all nutes, 6.5 is good for last weeks of flower for that P and K uptake

    Ah on the bottles of the 3 part formula it talks about micro and grow for seedlings 1ml of each per litre of water

    Whatever you do with nutes do it at quarter strenght of whate er they say.. maybe work your way to half if need be, rarely if ever will need more than that

    I have used those gh 3 part nutes b4, feed using 3 bottles since you have them, look on the back of the bottle their will be a seedling feeding schedule, feed at those ratios but start out 1/8 strength
