Rusted spot on my ak 47

Its flower time in the 4 week rusted spots are on the new leaves .
3x3 tent
CF Grow lights
5 gal top soil
i added cal mag 4 days ago
using foxfarm tiger bloom for the second time so far.
ph is around 5.5 temp 75 - 83
humidity and heat are is all over the place having a hard time with keeping that constant.

Please HElp i don't want to loos it.

Keep giving less N, more P and K and calmag. Try adding some big bloom too. Purple stems suggest low on magnesium

Your main problem is to low ph

And that too... 6.1-6.5 is good for soil grows
