be patient bro. They will fill in. But you can always add Co2.

That looks like it will fill in nicely. I like to foliar feed with botanicares boost.

Molasses 1-2 TBLS per gal of water 2x a week .You will be amazed

jizz..the best natural nutrient..hella protein..try it buds twice as big

i'd say menergy or some real lightening. can't go wrong with either
