Is this PH problems?

[Think]

I'm on day 21 now now and since day 7 ive been getting rust spots. now on some new leafs im getting small brown bits on them. I'm using PH perfect nutrients and haven't bothered checking because I'm following tangs schedule and he doesnt check the PH. im using calmag also and nothing has worked. im using palgron light mix for my medium. here's some photos these where taken yesterday. on the bottome 2 you can see more of it

Looks like you splashed the leaves with Nutes. Not quite true saying Tang doesn't check PH he knows his tap water PH starting out and how the nutes effect it. Always worth checking your waters PH even if your growing in soil and relying on buffers. If it's too far out of range it could spell trouble. Your plant looks fine though. Laters

Bunny got you straight.... if you think it's ph then start giving your water a check at feed.... I know exactly what mine will be after nutes but for some reason I still check every time.... and your plant looks great those few sports shouldn't be a worry....

It couldn't be nutrient being splashed on the leafs because new leafs are getting it and seems like its spreading. I've checked my PH and the water is 7.0 after nutrients is added its 6.0, runoff is around 6.0

Are you using a cal+mag supplement? There a bit on the lime green side.. you need a cal+mag supplement. I use boticare it has cal mag and ion.. never fails me even under LED..
edit you are using cal mag what kind? and how much?

Hia mate I found out its fungas gnats... How can I get rid of the maggots and flies? seen the little bastards this morning

Bug traps. And maybe a top coating of some sort of none water absorbing medium. Like hydroton or pea pebbles. I believe, could be wrong here going off memory, but if your top layer is super moist they lay their eggs and then they hatch in the nice moist soil/coco, what have you. Could try neem oil too.

Okay thanks would you recommend sand?

Idk. I tried dia tinaciuo earth (that is not spelled right) but when you top feed, well it turns to shit in one feeding! Sand may drain better, but I prefer hydroton. need something to dry out the top layer, where they lay their eggs.
