    Since I have found Harley's lectures here on UA-cam I have completely stopped looking online and wading through dozens of people's opinions concerning one subject of plant growing that would get me nowhere. I come here and my question is answered and the problem is solved.
    Thank you for these lectures. They have saved me much trouble.

      Bob Wags me too. I even looked up his university. I might take his online courses. I already am adding his supplements with my nutrients. My plants love it. I want to learn how to spoon feed better.

    When working with dry nutrients I realize that I wasn’t mixing it correctly after following the jacks nutrient formula I realized the calcium goes in last.That solve the issue to my leaves turn yellow the chemistry wasn’t right on the mixture Because I wasn’t giving it a thorough mixing now I use a pump inside my water at the bottom of the barrel to make sure it is thoroughly mixed in other words I was putting in all the correct things at the plant need it but it wasn’t binding correctly and that’s where my issue was happening hope this helps anybody using drain nutrient

    I have found that to be true the yellowing start at the tips of the leaf you can catch this early there are a few other reasons why this can happen.
    1. Over watering and feeding.
    2. High PH I try to keep my ph in a low to mid range for any of my plants 5.8-6.3 in most cases.
    3. Nitrogen Deficiency
    4.Bug Infestation Spider Mites And other sucking bugs ut sometimes it is not easily seen by the leaf it could be under attack from the root zone and hemotoads are the best way to ride your self from trips and Rust Gnats All natural is better then any
    pesticide that could harm you so I personally use YUKA with the hemotoads or i use Neem Oail and peperment and a all natural soap to help me of the problem on the leafs zone I have used lady bugs as well but if you do not catch spider mites quick enough they will take over your crop and nothing is a 1 spray fix you will have to spray your plants 1 or 2 times a week for the next 2-6 weeks to make sure any eggs that hack die you can use sand about 2 inches as well to stop gnats most of the time i will use 1 gallon of water then cut it back to 1 quart or 2 quarts most of the time i drown the gnats if i se they keep coming back I use Sand..

    • @missanna208802
      @missanna208802 6 років тому +1

      I don't know if you ever figured out this issue, but I had some rescue cattleya orchids that...ok normally they make at least one growth a year, these didn't make any for a year. They just sat there. I finally thought that they might have 'hidden hunger' and used a bloom booster on them for the higher p and k and in a few weeks, they had ALL started new growth. I don't know what kind of plants you are growing, but sometimes changing the light schedule can help too. If you find out where the species grows in nature and when it grows (usually during the rainy season), all you have to do is figure out what the day length is at that latitude at match that day length, though I prefer to drop them to 12/12 for a month beforehand to 'restart' them, then raise the day length up over a period of a few months. It's one of the tricks we use to switch plants from the opposite hemisphere to our own light schedule.

    I'm growing in a mixture of peat, coco and soil. Can I use your RAW products for soil? I explored the website and only saw a recommendation for hydro.
    I'm assuming that I can but might need to change my dosage?
