Light bleaching or lockout?

[Brock saunders]

I have a almost six week old gelato auto from 420 fast buds
Growing in coco peat
24h light
California light works solar extreme 250
Running flora trio from Gh

Not sure if it is a deficiency or light bleaching/burn
Lockout
Salt build up?


Thanks for any help in advance

How close is your light?What dosage of nutes are you using?Are you using cal/mag?

12 inches that's what the manual says for flower
And this is schedule I have been following

In coco, you need to monitor pH and ppm going in, and coming out, with about 15-25% run-off each time,... coco is a specialized soilless medium, it can't be treated like true soil or problems will pop up constantly,... without this info, we can't be sure of anything for cause... off pH, ppm's out of range causing a lockout/poor uptake,...
...symptoms are looking like Zn defc., either from lack of, too high pH, or an uptake issue because of the cation load in there,.....
best flsuh with the right solution, water alone is a no-no in coco, it'll screw up the CEC which I suspect is already there.... coco gurus say use RO/Di water, with 150ppm Ca-Mg, plus another 150ppm nutes, pH to 6.0; collect run-off to test for ppm and pH to see what's going on in there, especially initially... stop flsuh when ppm and pH are at or near input values, then resume proper nutes and feeding... coco is basically a hydro medium, it's all about keeping a steady, moderate supply of nutes in there,... true soil is far more flexible for give-and-take and the holding of nutes,...

I also thought it looked like Zn deficiency
I have been keeping the ph between 6.2-6.5
Since day one and didn't really worry about ppm
I did flush the plant like you said and it seems to be stretching again about an inch a day so hopefully all will be okay now

This could be your issue right here! In coco you will want to keep the ph right around 5.8. 6.2-6.5 is too high and meant for soil. Prolonged use at this high ph level will cause lockouts/deficiencies in your medium!

So the reason I was running 6.2-6.5 is because the hydro shop i purchased the mothers earth coco peat told me it was more like soil with the peat that was in it and all of them were having good luck at that ph but i can try and lower it and see what happens

Ahh my bad, I missed the coco-peat part. I thought you were just in just coco and that may have been your issue.

It's all good I probably my fault for not making it more clear
This grow is beating me up pretty bad have spent so damn much money for everything to be right and it's just wrong lol
