Older leaves dying

This is my setup for two feminised white widow plants:

- 59 watt fluorescent bulb which was intended to be used along with my main HPS growing light which should have arrived a long time ago, but didn't because the post office somehow managed to lose my package.

- Two fertilizers:
45-0-0 when it was vegetating and
6-18-12 + 2% Ca, B 0,06%, 0,08% Mn, 2% Mn, 0,05% Cu, 0,005% Mo, 5% S, 1% Fe, Zn 0,2% now that it's been on 12/12 for a few days.

I'm not sure what kind of soil mine is.

Thanks a lot

Please help. =( it's my first grow and I'm clueless

Would like to see a few more pics. Are more leaves dying? or just the two in the pics? Bottom leaves tend to dye over time, especially when there is not much light reaching them.

Please send a little more info about your nutrients. Brand, dosage, PH, all that good stuff. But in my opinion, whatever thats worth, if the dying leaves are not spreading then dont worry about it. Cut them off.

im a noob but ur soil looks weak. its prob nute burn though.
