Help? 7 Weeks Flowering

[Captaindank]

Hey guys this is my very first post on here. My plant has been flowering for about 6.5-7 weeks now. I have been using Fox Farm Grow Big, Big Bloom and Tiger Bloom. Soil is FF Ocean Forest and 30% Perlite. PH is about 6.5, and I water about 3/4 gal every 5-6 days. Night temps are about 70 and day temp is about 80. Humidity is about 40%. Roughly 300-350 watts of 2700K CFLs for lighting (I removed some for the pics). Trichomes are still mostly clear. How is it looking? Top leaves look to have a little nuts burn and some of the middle/lower leaves appear to have a deficiency (last pics). Any advice? How much do you think I have until harvest?

It looks like they still have a while to go
ive only grown with floros once but imo it takes longer using them.
Plant doesnt seem to be yellowing as it does when it begins to ripen
So i would say give it some time.
