Grow Big is 6-4-4 and ought to help. Reduce your P and K from the other sources accordingly ... or if you use a hydro store see what they can recommend by way of an N supplement. cn

That looks fine. You will be done in 4 weeks, these next 2 weeks is when your buds will really grow. Keep feeding using your nute schedule.

Its ok to have some yellowing and lower leaves falling off. It really is not a big deal. The true indicator is how your buds are doing, and they will get the deficient nutes from the surrounding leaves.. You are going to flush anyways during the last 7 days. SO your really have 3 weeks to go.
get a microscope to check your tricomes

Relax, keep your schedule and don't change a thing

Man, you lighting is possible, get a 300 or 500 LED atleast. Not much will change your yield with those lights

yep i agree, at this point there's not much point in worrying about the leaves. I'm not sure about N either - this could be overfeeding too.

sum Big Grow in the 2nd and 3th week of flowering?
Their feeding chart says 2 tsps 2nd and 3th week of
flowering I usually add 1 tsp to be on the save side.........

LOOK AT THIS CHART.......!!!!!


it needs to be ph 6.5.
at ph 6.8 you are missing (Mn) Manganese and (Fe) Iron, you can see that on the right hand side of the chart, the left side is ph 5.8 for hydro.
your plant is locking these nutrients out at ph 6.8.
also make sure you are giving them a full nutrient diet.

also plants do not like light from underneath, grow rooms have white/silver walls and black floors to dull the light reflecting of the floor, plants respire air from beneath the leaf and accept light from the top of the leaf, so the top of the leaf can get very hot but underneath it needs to be cool under the canopy, correct this too, lift all your cfls a little just so the light is shining down on the plant and get some air underneath it.

yeah but not just like, give it more N as it is. To provide more N, flush your soil well, then use the same amount (ppms) of nutrients, only with *proportionally* more N.
