Yellow spots, black spots, droopy leaves. Day 28 Think Different

[jbg333]

Hey guys...

Looking for some opinions on what's wrong with my plant and what I might be able to do to fix it...

I'm growing in OF under a 400W HPS. Only nutes so far are Rhizotonic, which I started on week 2 and Cannazyn, which I started during the last watering.

Ph in is 6.0, out is 6.2... Temps are 84 lights on, 72 lights out.

There does seem to be a little salt looking residue on the outside of my smart pots, so I don't know if that means ive over fed them or what.

I eased them in with the nutes up to full strength, so I don't know if I just do pure ph'd water next time?

I'm on day 28 and wondering if I need to start my flowering nutes (Tiger and Big Bloom) or if this is a completely different problem all together.

Any input is very much appreciated, thanks!

Thanks for the link, I read through and i don't think its light bleach because i don't folia spray... maybe i should start doing it @ lights out?

Im thinking i may have overfed them the rhizotonic root stim. ive been doing it every watering since about week 2.

I eased them into it, but i think they may have had too much.

Hope she recovers...

Any more input is appreciated!
