transplant into bigger pot, and paint the pot white. White reflects light. The pot will not dry out as quick, and it will not get hot enough to damage the plant's roots.
If you use MG water soluble nutes, make sure you feed lightly.

Have you heard of cloning? You can take a cutting of the plant, and root it. It will be an exact replica.
If your feminized plant is an auto, then you should consider using the colloidal silver.
I don't see any male parts. That looks like a calyx. The brown center looks odd, like it might have a seed in it? You should cut it open...
Plant looks pretty good. You might have overfed it at some point, that is why you have some dying leaves.
I would like to store the pollen for at least 3 months. I have tried to store pollen in glass containers in the past, and it got moldy.
What storing method has worked for you? How long did the pollen last?
Caterpillars. The little black balls is caterpillar shit. You will have to inspect the cola that is falling apart, and pick out the caterpillar before it does more damage.
