Frass, kelp extract and TM-7 are all cool. Especially as a liquid feeding, or "nutrient tea" to keep a steady supply of the hard to get micro nutrients. Here's a recipe I copied from some dudes on the Internet.
I would still think about mixing something into your soil. It's cool to top things...
Looks like you need Nitrogen, Potassium and Micros.
For N you could try. bat guano, neem seed meal, soy bean meal, or anything else you could think of that has Low Phosphorus. So no fish meal or crustacean stuff.
For K you could try A Little Potassium Sulfate. It's pretty concentrated, so be...
You could add more Inert stuff like aeration and peat moss to dilute or water down the nutrients that are too high.
Then you could find a way to add more micronutrients to bring up the levels of nutrients that are too low.
Maybe you could try Flushing some soil with a bunch of water to...
The langbeinite is pretty water soluble, so I imagine that it's not very slow release. Or that it is released quickly.
That's why you'll want to let your soil "cook" or "age" after you mix it up, before you use. Give all the nutrients time to break down and be absorbed by the soil. That way...
I agree that you'll want some more Nitrogen and some more Potassium in your mix. I'm using the same stuff as you, plus some Bat Guano for N and Sul-Po-Mag (also called Langbeinite or K-Mag) for K.
For the N you could add some Bat Guano, Neem Meal, Soy Meal.
For the K, I really think the...
I add mycos right to the roots at transplant.
Then I brew teas later for bacteria and maybe (hopefully) what ever other fungus grows in compost and EWC.
I've read that myco fungi don't reproduce when you brew them in water. But getting the spores wet does soften their outer casing and get them...
It looks like they are a little burned.
You've got lots of dark leaves, and shit looks frosty, so your plants probably aren't hungry. So the burned edges and leaf curl look like over feeding to me. It doesn't look to bad, so don't freak out. But maybe relax on feeding for a minute.
To make...
Yeah, I agree, probably a little bit of Burn.
16 tablespoons or 1 cup is a lot to dump on top of a 5 gallon pot all at once. I would use like half of that for a 7 gallon pot. And your plants are really green and leafy and healthy looking otherwise, so it's probably not a deficiency.
I think...
If you cut clones from growing tips near the top of the plant, especially the main stem, your nodes will be tighter.
In my experience bottom branches tend to produce clones with thinner, longer stem and bigger internode spaces. I grow from clones of clones of clones... Over time when I cut...
It Depends. What's in your soil and how you are feeding your grow?
Plants need at least some Phosphorus at every stage of growth. So if you're in an inert medium like Pro Mix or something, without feeding anything else, you'll need some guano (or fish bone meal, or what ever else you like to...
Like you said, plants like lots of room when you're growing in soil. It's not like Chem based setups where you can grow huge plants with tiny root mass.
You could Probably get away with 5 gallons pots of your plants aren't huge, and you keep feeding them. Which you plan to do and have all the...
All "organic" nutrients have Nitrogen in the form of amino acids. Kelp. alfalfa, fish guts, etc, etc. Glycine and Glutamic Acid are two that are specifically linked to calcium uptake, and they're in just about every fertilizer that used to be alive.
Hydrolysates are like refined forms of...
Try to get started on that stuff a week (or more) before flip.
It's not just about recovery. Lollipopping is training too. Cutting the lower branches makes the tops grow taller. You want the plant to have some time to grow into that Long Cola with no side branching shape.
If you wait to long...
In this picture your plants don't look hungry, it just looks like your tallest plant is being melted by the light. Look at those tall, green branches under the edges of your light. They look OK. Then look at the middle of your plant, just under the Hot Spot in the middle of your light, all...
