First grow need help!

This is my first grow ever. Week 4 of flowering. Northern lights auto and pineapple auto. Started with just a pot in my room and slowly upgraded to the tent, bestiva 1000 watt light, Vivosun air filtration. No nutes until they started to flower then used tiger bloom. Think I might have used too much. Fan leaves turned dark and shiny, now they have yellow spots and look like they are dying. Been using just purified water to flush. Do they look like they should at this point? Lower buds are still pretty small. Ordered nutes and ph testers for my next try. Any advice at this point would be very appreciated!

@Myfriendis410 is awesome at identifying problems. I’m not because I never had to deal with them.

You commented on another post about potassium deficiency. Do you think that’s what’s going on because of the black spots on the leaves?

Possibly…most that post Phosphorus deficiency its real black. Yours could be another. @Myfriendis410

@Covertgrower and @CoyoteCody


I see calcium deficiency, phosphorus and excessive nitrogen, then lack of.
The fan leaves yellowing a little early.

A lot of this is the lack of PH tracking. If your ph falls out of line, a lot of, and some nutrients aren’t available for uptake. @Jastur66


Looks like @Covertgrower has you covered. Sorry, out in Colorado looking at our house build.
