Extra Nitrogen for week 3-4 of flower?

I'm about 3 1/2 weeks into flowering (pure power plant) using fox farm trio (except I don't have grow big) Some of my plants are showing yellowing on the fan leaves and they look like they could use some extra nitrogen. Right now I'm feeding them 1/2 strength tiger bloom, full strength big bloom and 1/2 tbs molasses. On the feeding schedule it shows using grow big in week 3 and 4, but since I don't have this I was thinking about using maricle grow all purpose 24-8-16.

How would I incorporate this into my feeding schedule ? This is my first grow and It's going great but I'm scared of over feeding. I was wondering if I should use it and the tiger bloom or not. I was thinking about feeding them with 1/3 strength miracle grow with the big bloom and molasses and leaving the tiger bloom out for those two feedings.

Any thought?

hey ur doing pretty good, too bad u dont have an ec meter though. I had the same issue with TB and just supplemented w/ some 2-2-2. My first grow too i think im day 47 of flower, the calyxes are just starting to explode. i believe ur plan is sound and should have no prob. Personaly I'd use both the miracle grow and tigerbloom for the next two feedings for a more balanced npk. the yellowing is permanant damage, so keep supplementing the miracle grow as needed to keep the plant green.

Thanks, I wish I could of caught this a little sooner but it really isn't that bad. I didn't notice cause its mainly effecting two plant in the back of the closet and the leaves that are showing the problem are below the canopy and kinda hidden.

Would using 1/2 miracle grow all purpose 24-8-16 be to much? I dont want to over fert but I don't want to give them to little since their deficient .

Leaves below a thick canopy that aren't getting light are subject to release by the plant because it can't utilize them, so it drains them of their nutrient content and drops them. Can also be caused from being rootbound.

Try and look at your plant as a whole to determine wether or not its actually asking for nitrogen. If its robbing it from the lower parts of itself it will likely lack strong growth.

Yeah its definitely apparent in the canopy, thats how I noticed it, then I saw it had been working It way up from the bottom of the plant.
