What's wrong w my plants? (pics)

Whats the issue here and how do i fix it?

sorry i posted this in newbie too. my bad. saw this section after...

you have to give details of the grow no one can give definite advice just by a picture alone.....

sorry

5th wk flower
mg soil
molasses twice last 2 wks
mg bloom boost every other water
last water just water
cfl lights

have to realize all energy is going towards bud production the plant is using itself up your going to lose some fan leaves....

looks like nute burn. Have you thoroughly flushed your soil with plain phed water? N defs are common in later stages of flowering.

well does my bloom boost address N? i think its 10-30-10...

is watering w just water same as flushing?

if its burn, how can i fix N issue w/o burning more?
