    Default Answered: Is it the problem with Nitrogen or something else?

    Hey Guys,

    Hope that's not a problem to post my second post as a help question.

    I'm growing 2 Laughing Buddha plants in soil. They are both about 100 days old.
    12/12 from seed, but they had a big problems with soil at the beginning.
    Now they are in BioBizz Light Mix soil, and I use BioBizz Starter Pack as a fertilizers.

    Last two weeks under Led Light PlanPhotonics 85W before MarsHydro "300W"

    Is this a problem of lack of Nitrogen in early stage or something like that?

    Thanks for help Guys!

    Lowering the N would help as they are overfed, but I believe you may have another issue or two. What are temps/ humidity
    If only I grew cannabis well

    This is actually looking more like a phosphorus deficiency

    If there was a lighter green around the rust dots, I'd agree, but because it's a dark green, it's excess mate. Need to get some of the food out of the medium, and restore the ph to optimum level

    Wow Guys!
    That's a great response to my question! Thank you!
    It was a good idea to register on this forum.

    So I've check the PH of soil.
    Basically I've put the pot in a basket watered it with 6.2ph water and checked the PH
    of water that came out the pot. I've checked it with the yellow PH meter is it ok?
    It was 5.5 - That's wrong.
    So what should I do to restore PH in this soil? Should I water the plant with PH 7 water, or flush it with 6.5ph water?
    What's the best way?

    To clarify the overfed problem. I don't think it's possible. Because I fed them really low in fertilizers for most of their life.

    They dont need food much at all in soil, if you fed to early, before there were a good amount of nuits in the soil already eaten, then there will be too much in there, as they wont eat it all. Also, the plant uses different amounts of NPK at diffrent times of the grow, so some things will only show up ate certain stages. Id say just a small flsuh at 6.5 might fix it up a bit. give it a good watering with plenty of run off, but then leave it a few days to dry out, its really easy to over water so you need to be careful. Good lfush until the run of comes at 6.5 then leave them to dry out for a few days. That should fix the problem

    Thank you guys for all your answers!
    I should know that already, PH of soil is the most important thing!

    That's why I always fail to deliver on harvest
