Nutrient Lock ? Nutrient Burn ? Help ?

Hello,

I have some plants in a vegetative state, they are ready to start flowering.
Some of them started to have problems with the upper leaves. The shoots are yellowing and emerging with the leaves curled upwards.
I don't know if it was an excess of some nutrient or some kind of nutrient lock.

Would anyone know how to help me?

I use nutrients from REMO and I use Carolina Soil (Peat and Vermiculite)
The filtered tap water I use is 400 PPM.
I have been using CALMAG every time I water, I believe that was one of the reasons for the problem.

Looks like pest damage, either Broad or Russet mites..

I'm going with salt build up. I'd go with half nutes you were doing before and really get some runoff.

Thanks, I was really thinking about that possibility. I'll flush the soil.

I don't think it's pests, I really keep my grow clean.
I'll try to look closer, using a microscope.
Thanks.

Looks like broad or cyclamen, but probably broads. Russet mites have a unique shape that look like a carrot. Have you visited any other people's grows?

Sorry man. There's a guy on YouTube I think Green Gene's Garden or something like that. He documents an entire grow battling russets and what he did between harvests to reset.

Hello, thank you for yout attention.
No, I've never been to other grow.
I believe it came inside the substrate package. The only place I could have gotten this is the grow store itself. I think they store substrates poorly, and they sold me an infected substrate. Thanks for the tip, I'll check out the YouTube channel.
