Can someone tell me what’s going on here? i thought it was light burn/bleaching but I’m not sure.
I believe I have the watering down.Could be overwatering or feeding but allso could be a cal deficiency.
There’s no bugs that I can see. I really believe I have the watering down. The root temp I high 70’s low 80’sYeah look like both calcium and magnesium to me. But more importantly finding the root cause is what ya need. I wouldn't just start add cal mag. Usually it's not that there is to little but for some reason there is a problem with uptake. Could be ph, watering, root temps/health, bugs or other. I'm a hydro but the dirt guys should get ya sorted out.
Okay, I’ve been watering with PH of 6.8 to 7.0 which is suggested with organic grow.Like I said not a soil guy but maybe a slurry test on the soils to determine ph will help ya. I'm sure the soil guys will get it figured @Jimster @oldskol4evr @OldManRiver @MIMedGrower and I could make a list a mile long. I think @Beachwalker is right. Could be lockout as @az2000 suggested.
Like I said I'm a hydro guy.
Yeah I mean the ph of your soil. I'm thinking if all else was the same it may be the ph of your soil that could be different since that's the only difference that's jumps out at me. Your soil will buffer whatever you out into it. So if the ph of the soil is different you can add the same ph feed but it will likely not end up being the same ph in the soil. When making a new soil mix it's best to do a slurry test and confirm your soil pH is where you want it before you plant since it will have a huge impact on your ph throughout your grow.Okay, I’ve been watering with PH of 6.8 to 7.0 which is suggested with organic grow.
I will look into the PH further. But it’s of that #3 is doing fine with the same regimen.
Thank you all for your responses.
i got to disagree with you bro,hydro soiless or soil ,plants are plants all require same thing,takes talent to read them and your on top your gameLike I said not a soil guy but maybe a slurry test on the soils to determine ph will help ya.

I don’t water to run off. My understanding is you don’t water to run off with an organic grow.I suggest watching your runoff ppm. That can suggest salt buildup (too strong nutrients, too little runoff. I don't ph my nutrients. I don't believe soil needs it.). What stage of growth is this?
I don't grow in an organic medium, I use Promix. I don't think it matters too much what type of medium that you are using, but if it is a soil "like" medium, ie Promix, Coco, etc, it can hold water and nutrients. After a while, if the nutrients aren't used by the plant and doesn't drain out of the bottom of the container, they will begin to concentrate. Once concentrated, it acts the same way as a nutrient imbalance or a deficiency. The usual reaction when this happens is to dump Cal-Mag or more nutrients on it. This increases the nute buildup and concentration issues. Can you see the endless cycle?I don’t water to run off. My understanding is you don’t water to run off with an organic grow.

This is the reason that I like to see some excess water drain out of the medium, and is also part of the reason that I only feed every 10-15 days instead of at every watering. These are just little things that can make big differences as you fine tune your growing procedure to best fit your situation. Organic is great, but it doesn't mean that the plants can't be easily destroyed by the organic stuff that is used. Keep the nutrients low and make sure that you have good drainage and you shouldn't have any problems. A TDS meter might help you to keep tabs on your medium's nutrient contents. Good Luck!!
I have answered a few posts recently about using the living soil, and varieties with it. I don't know much about it other than the suggested benefits of using it and trying to replicate the naturally existing nitrogen and nutrient cycle. This is more like growing mushrooms than growing Cannabis, but the point I wanted to make was that the Organic grows that I have offered my opinions on have had problems using straight organic materials. Cow manure is unbelievably high in ammonia while fresh, and when composted, has a very high nitrogen content. Despite this being natural and organic, it burned the shit out of the guy's plants. I guess the lesson is that organic is great but can have the same problems that non organic guys have. A TDS/PPM meter would show the high levels of nutrients in the soil, regardless of the origins of it. I prefer to know what I have put into the medium and try to keep things to a minimum as much as possible. I'm basically lazy and would rather feed a little too little than to have to deal with overfeeding issues.From what I've read, organic soil growers want to keep everything in the soil (nutrients, beneficial microbes). Let the plant use what it wants, when it wants. Don't wash things away. Be ultra conservative.
I'm more like you. I wipe the plate clean (a little) each watering, and replace the nutrients with a rebalanced mix. A little of both worlds. Not entirely synthetic nutrients. Not purley organic "let the soil and plant coexist as God intended them to." :) (I don't mean to be sarcastic that way. I'd like to grow a simple, complete living soil and see how it works. It makes sense in many ways.).
I don't know how runoff ppms would reflect on the soil's content in that case (when the content depends on microbes breaking down organic material). I don't know how that translates into salts, dissolved solids. That could be a limitation on measuring runoff ppm.
The only thing that would make me uneasy about not watering until runoff is that I'd never know if there were dry pockets in the soil. I.e., how do you know what's enough water without seeing excess running out?
It sounds like the OP should google about "teas." I think that's how total-living soil growers keep their soil balanced, rejuvinated. (I don't know much about it.).
