Hi guys, this is my first post on here and I need your help!

I'm currently just over half way through my second grow (the first one was pretty bumpy as I made a lot of balls-ups). Everything was going absolutely swimmingly second time around until last week when I started to notice signs of either nutrient burn / lock out / deficiency ... but I'm really not sure what it is i'm looking at.

Seeing as you lot are the experts I thought I'd be better off asking you lot for your opinions on what you think the issue may be. Here's a full list of my set up:

- Northern lights (photoperiod) grown INDOORS from seed currently in week 5 of flowering
- Plagron light mix soil with approx 30% perlite
- 10 litre airpot
- 180w UFO led grow light and 2x23w supplementary cfl's (all about 10 inches from top of canopy)
- 1 x 4 inch ventilation fan with carbon filter attached
- 1 x 4inch circulatory fan
- Average temp's 19 - 23 degrees c.
- General hydroponics 3 part nutrient system (grow, flora & micro)
- Plant magic magne-cal
- Un-sulphered black strap molasses

I feed approx 2.5 litres every friday at around 1100-1200ppm and water approx 2.5 litres with just magne-cal & molasses added every tuesday at around 350-450ppm.

I ph my feedings and waterings at around 6.2 and run off reads at around 6.6.

I'm a bit stumped as I did so much god damn homework before starting this one and I can't figure out what it is?! Going by diagnosis photo's on google I presumed it was a calmag issue but I feed 1.5-2x the recommended amount on the bottle and also supplement with molasses... HELP ME PLEASE!

Thanks
