Nutrient deficiency?

Hey everyone I noticed some of my new growth has yellowing on the leaves, anyone have any idea what could be causing this?

My soil is ffof and a 600w hps for lighting

Ph is at 6.5 btw

Looks like some mag deficiency but I’m no expert. I’m sure someone knowledgeable will pop in with help soon. What is your soil and nutrients your using ? I’d hit it with some cal mag

I'm in ffof, my nutes is botanicare pure blend pro which I used a small amount of only once plan on not using it for at least a couple more weeks cause I hear ffof is pretty hot to begin with, although I did have my lights kinda close to the plants before I'm wondering if it could be light bleaching? Have moved them higher since but I will grab some cal mag tomorrow!

So I got me some cal mag and while I was waiting for the pot to dry up so I could feed it to the plants with the next watering, i ended up reading up on pee fertilizer and how good it is for plants. So I figured what the hell might as well, I got my little 5 year old and got her to pee in a bucket for me (figured her pee gotta be healthier than mine lol) watered it down about 1:10. So yesterday I mixed the pee fertilizer with cal mag and only half the recommended notes (botanicare pure blend pro) and lo and behold!! The yellowing pretty much disappeared over night! I think my little ones gonna be peeing in buckets more often

See, FFOF ain't that hot. You never know, some bags are hot and some bags are just glorified Pro Mix.

truth is, since you gave so much stuff, you don't know what the solution was. maybe it was the mg, who knows? guess pee couldn't hurt.

That's what I was thinking but I figured it's all organic anyways cant hurt it that much so long as I dont over do it, and it did respond well so I'm happy for that next watering just giving it nutes, but I got the pee and cal mag handy in case I need them again

did you know that urine has ammonia? one reason why it stinks.

Ammonia is high in nitrogen, but I dont smell anything at all cause what I did is put a bit of the pee fertilizer in first then applied the cal mag and nutes so to wash the pee into the soil worked like a charm!
