  2. That would appear to me to be a Magnesium deficiency. A tablespoon of Epsom salt in a gallon of water, foliar sprayed at lights out may help. If you’re in coco and not using a calmag supplement, you should start.
     
  3. Can you give details about the medium, ph, temps, lights, nutes etc.?

  5. That changes things a bit. You need a base nutrient. You’re using a microbe tea and a beneficial fungi product, but only the FFOF for nutes. The plant is big enough it has depleted most of the nutrients in the soil and it’s time to begin supplementing with some form of NPK. That’s what is causing the mag deficiency. She’s hungry!

  6. Adding to this, if i were you i would topdress with some balanced organic material and work it in then water with a good aact and maybe even spray the plant with it too, seeing its still vegging. You can add some epsom if you like too, don’t go heavy with any of this and see if it makes any positive changes if it does you can topdress more. People try to correct one thing at a time to pinpoint the specific solution but i would do both since they are both nutrient kicks.

    Wormcastings are very low in npk values, dont know about the special sauces you have in there but i use some readily mixed dry organic fertilizers appropriate to the life stage. At this point i would have used my 3-4-3 gk organics mix. All those special sauces could have thrown off your ph too thats something to look into. It may be a lockout. It kinda looks like a lockout of some micro to my newbie eyes actually.
    Edit: Looked at the ffof and it seems it has some good organic material already in there, maybe ph is the culprit.

    Pick ur favorite veg fertilizer and hit em with it and watch that plant turn green again b4 ur eyes. . Ur plant is hungry. Pure and simple
     
  11. Is that a mychorrizal product, if so one application should suffice. Whenever i get some problems a good balanced aact clears that up or i have been lucky so far.

    ok cool got it...what do you like to use for your compost tea if you don't mind me asking do you use stuff I could buy at build a soil
     
  16. You need grow.
     
  17. I do my veg teas with wormcastings, molasses, kelp extract, fish emulsion, diatomaceous earth and sometimes with alfalfa for tricontanol and stinging nettle for all the micros and enzymes.
     
  18. Ive been using down to earth blood meal and fish meal. They are both a great source of nitrogen. To help the plants out quickly, age old kelp is great as a foliar spray. It will give an instant dose of nitrogen directly to your plants. You will see a major difference over night. Top dressing can take a few days for your plants to really start uptaking the nutrients. A foliar spray will keep them happy until that happens. You can also use the down to earth nutrients to brew a tea. No matter what I always hit them with some cal-mag just to prevent a defficiency. 20180714_091945[2].jpg
