@@Athos, Thanks for the fast reaction! I got a ec meter but its says 730 , i did Some reseach and i think that should be 1.2 ec or something.. thats not bad right?

Get an EC/PPM meter. Hard to say with no feeding strength data. Yellow leaves (chlorosis) with rust spots in the bottom leaves is potassium deficiency, which is normal in flower stage. You might be getting burnt tips because the soil might be too prefertilized with nitrogen. I would stop the veg nute and focus on the bloom for now.

Bigger pot for the smaller one and just clip the dead leaf off
