Some sort of deficiency

First time indoor grow, growing in FFOF currently on week 4 of veg. Ive only given nutes once, using tap water (pH 6.5-6.8) and fox farm trio. The top leaves of my plants are losing color, I’ve read a bit and it’s clearly not nitrogen deficiency because it works itself up the plant. Thinking about magnesium, has someone been through this?

It's less available at 6 to 6.5. I grow in fox farms happy frog and ocean forest normally I'll try to water at a ph between 6.3 and 6.7 when using liquid nutrients, giving it 7 sometimes. Epsom salt is an organic magnesium nutrient.
Thanks, I’ll be adding some magnesium. I usually water around 6.5-6.8, I messed up on my typing, but thanks for that pH graph.

So I gave them their first round of nutes around 5 days ago, I don’t know if it takes more for them to recuperate or damaged leaves just stay like that. Got a brownish with yellow tip on the leaves now, and new leaves seem to have some kind of white yellow tip. Any guesses?

Is that PM?

I think thats because I gave it some foliar with epsom salt. I’ll check for mildew though
OK. Ya, those plants definitely want some Mg, but FFOF should be good for a month without having Mg deficiencies. Makes me wonder if you are doing something to cause pH issues or something. Are you using pH down?

I’m on week 5 of veg now, I was waiting for some signs of deficiency to give them some nutes. That’s when tips started to yellow out so I gave them some nutes fox farm trio. I’m using ph down water is anywhere from 6.3-6.7 and I fed them around 400 ppm
