What is this?

[Mañ'O'Green]

I have the understanding the runnof reading from soil can be very misleading and flushing soil most of the times will make the problem worse with soil.. This what @Mañ'O'Green said about flushing but he may have changed his tune since

"OF is Soil and you cannot successfully flush soil it often makes matters worse. Soil has elements like Dolomite lime and other rock hard sources of nutrients that the soil microbes break down into the ionic forms the plant can uptake. Flushing washes away all of the available soluable nutrients along will most of the living microbes but leaves behind the solid forms of nutrients totally out of balance. You have no way of knowing what is in the pot and no way of determining what to add back in to try to get the balance back. You simply do not have enough time to get the soil healthy again before the plants are done. "

Flushing soil is an absolute last ditch effort to get a nearly dead plant across the finish line. You are not there.

That does look like a Mg problem but the cause can be mysterious. If you are confident that you are not overfeeding then add 1g Epsom Salt per gallon to your regular fertilizer (mix in after part a, before part b in a two part system) It will not repair the past damage just wtch the newer growth for it to stop

I used Ocean Forest for a few years without problems. It doesn't need nutes for 3-4 weeks. Then begin nutes at 1/2 the dose.

what all nutes did you use? I can just buy mew nutes and not use dr earth

Ok i think my problem is I am burning the shit out of them. Causing lockout. The more I read, the more I think OF should carry a plant out to 6 weeks plus.

If these don’t pull through I will start over and run OF and add nothing but water and see how long it will carry me.

I found this to be true of Coco Loco.

I've used many nutes over the years. As long as you don't use too much, you should be fine with what you have. Less is more in the case of an autoflower.

I have run OF and it can go the first 5 weeks using RO only...Then run most any nute up too 60% with autos.... I have used the trio and MC 1 part with OF with good results no feeding till week 5

Last grow I used Dr Earth for the first time, and I had this too. Never figured out what it was. But I suspected a calcium overload to mag ratio. The Dr earth veg is 18% calcium. Bone meal is also high calcium.
Your in a super soil, no need for the Dr Earth veg ferts. I am skipping them this run and using the premium gold fert week 3.

It Dr earth's Premium Gold 4-4-4, as per their feeding schedule for cannabis, I had assumed you were using it.
Page 3 of the schedule is what I am roughly using. But since I am using a super soil, I will skip the green bag.
