My plant is out-growing itself.

[M.B.A.]

.....
Some will say, "The Granddaddy may just normally grow like that!" - But no, I have witnessed a good friend raise a GDP from clone to harvest. That clone never showed any of these massive leaves that couldn't be held up a day after watering; nothing close. I think I have over-grown the top of the plant with foliar feeding, and should stop - with this plant at least, until it can support itself again.

my GDP that I harvested last night has had Big-ass leaves since I've had it since clone to harvest. You can say what you want and believe what you want. If you believe that your foliar feedings are causing this, go ahead and stop and wait, see what happens
