Plant is slowly developing a calcium or magnesium deficiency i believe. Tiny orange dots on leaves, doesn't look like rust. It's not bad yet
Might supplement a little calmag next watering
It looks like you may have a Nitrogen deficiency. You see the yellowing at the bottom? It will work it's way up as it's a mobile nutrient. This can be fixed in one feeding. No need to panic. Also, double check your ph after mixing your nutrients just to be extra sure its between 6-6.5. Happy growing
@Dabking, Yes, i am working my way up on nutrients, at 50% strength now. Was a little lazy the first threeweeks since it's 30% fox farm soil with good nutes. Am doing 6.0-6.3 PH. Thanks!
