Have some plants in coco with 4-4-4, 7-3-1 earth worm castings and super charge. Rust spots started in between leaves and appeared on the top of the canopy.
Sick plant can’t tell what it is

Too much nitrogen. Also locking out, or need calcium. What brand is your 4-4-4 and 7-3-1?

thanks for the reply brotha,
what do you mean by ec, I water at 6.5 and I do use aired tap.

EC - how much nutes you put in your water.
If you don't measure and go by the plant, it's easy to over dose.
Get an ec meter if you use liquid nutes.
Give nutes every watering in consistent ranges according to the plant only, leave the math and science mambo jumbo aside.

Down to earth amendments, if locked out could I flush?

I use dry fertilizer 3 tablespoons of 4-4-4 and 2 tablespoons of 7-3-1 bat guano bag calls for 1-2 tablespoons per gallon and there in 3gallon containers

Coco and organics isn't easy. Did you let it cook first and for how long? Looks like nutrient imbalance. The rust spots might be calcium deficiency. The coco could have absorbed some of it.

You can flush but it's not recommended.
You want to shock the rootzone as less as possible, so first try to ph a little lower than 6.5, go for 6.2 or 6.3, it just make the absorption of different minerals better to swing a lil in ph range.
2nd, drop your qty of nutes to 75% next watering, followed by 50% after that, slowly seeing the reaction of the plant and stabling around what the plant tell you is best.

Leave the charts aside, go by the plant.

I'd cut the 7-3-1 and the supercharge. Just plain water until she lightens up a little bit. Flushing won't do much, it wouldn't hurt tho. Just water to ample runoff each time. If you are adding Guano, then you need to cut your 4-4-4 back.

He's using dry amendments, not salts

The 4-4-4 and the supercharge both have calcium and magneseum in them. If you are using the supercharge every watering, that could be your culprit locking out calcium. Less is more.

I've yet to see a successful grow with coco and dry amendments.........maybe this will be the first.
Looks like a calcium deficiency.
Good luck and welcome to RIU.

You think flushing will resolve the lock faster? If I water till runoff the next couple waterings wouldn’t the it keep getting worst between watering.

Peat is your friend when trying to do organics and coco, gotta have some peat in there.
And I agree, def a cal issue aswell, just I'm not sure if it's def or lockout.
You water till runoff with the dosage he recommended until the rootzone becomes a balanced level of what your trying to accomplish.

You can only flush what is already broken down. Any further flushing will just flush out all the microbial life in the medium. They will look better for a minute, then on e the microbes come back into full swing, you are right back here again. Just water, let the microbes break down what you already put in and let the plant use it up.

Definitely agree with the Pete. I use promix bx and dr earth.
The dr earth is similar to the dte he uses. If I add too much, even kelp in a tea, I see calcium lock out.
