plant problem

What do you guys think?

I have some crinkling of the edges of some fan leaves and burned looking spots on new growth on the buds.

Plant is a dinafem blue hash

My other plant is a rocklock and it is yellowing bad

both are 4 weeks into flower I started using molasses last week

I gave a light dose of FF nutes on last friday and some today

there is a marijuana plant problem thread..try there.
