Need help

In second week of flowering, day 11. And the lower leafs of my plant is starting to yellow and drop down completely, the upper leaves are dark green and the buds look nice no probs up there. But the lower leaves first get yellow between the veins and then completely yellow with just a few spots where they look burned. Have looked at all possible reasons for this but none are right on..I'm growing in dirt, using biobloom and topmax, and the strain I'm growing is ICE. Need help quickly really worried about my baby =/

Have you got pics.
- Nitrogen Deficiencies

Plants will exhibit lack of vigor, slow growth and will be weak and stunted. Quality and yield will be significantly reduced. Older leaves become yellow (chlorotic) from lack of chlorophyll. Deficient plants will exhibit uniform light green to yellow on older leaves, these leaves may die and drop. Leaf margins will not curled up noticeably. Chlorosis will eventually spread throughout the plant. Stems, petioles and lower leaf
surfaces may turn purple.
This could be the problem but pic will help. The lower leafs are the oldest and usually first affected.

I will post a picture in 5 mins thx for ur respond but don't think it's nitrogen

Magnesium is another candidate.
Could you provide as much detail as possible about you grow, age, feed, setup etc.

pic please!

Have already deleted 2 leaves that where completely yellow

Where do i get epsom salts ?

the apothocary/pharmacy

Oh , I looked there but it said on a website that it is no longer available for anybody to buy

And also, how much should I feed the plant ? And what can happen if overfed ?

use dolomite lime, then. from the garden center.

Thanks for the help so far will run to the pharmacy and see if they have it there

Found the epsom salt thing.. It's magnesium sulfate in my language.. It's in powder form for oral consumption ? wtf..
