    Professor have you ever seen plants form tips which are made up of what appears to be clusters of little immature leaves where white hairs should be pushing out the first week of 12 12 lighting, they appear to be overdosed on nitrogen and take a week to start putting out pistils. Looks somewhat like broad mite damage too.

    This is such a random video but funny enough, I watch this video instead of any I should’ve seen for school during it.

    Hi, what would you say is the ratio of npk on fish tank water? Mines is none-high-high



  12. Noname TrackZ on June 7, 2022 at 3:46 am

    What can we do if we added slow release nitrogen soil like miracle grow. i started using that before i transplanted to fox farm soil and now it looks like its really a toxicity

    Don’t know if your still checking your comments but, I have a question. Any problems with diluted urine (10:1)? Thanks. Sorry for being a little gross. lol

    Love the video and content. Thanks 👍 for sharing the knowledge. We need to support one another in OUR growing cannabis community. Much love and respect from Canada.

    Amateur growers be like:
    “1 spoon might not be enough for this majestic beauty that I have grown,clearly mine need a bit more….”
    Experienced growers be like:
    “1 spoon?……….half.”

    02:49 You didn’t talk about clawed leaves. If I’m correct, the lockout of N can do yellow and clawing leaves.



  23. callmemaybejammin on June 7, 2022 at 4:07 am

    Hey Mr.DeBacco Its Becca. Don’t think I need this for Biology or for chemistry next year. 😃. I’ll watch it anyway to support your channel.
