Yea, keep nailing them everyday. Switching up helps too sometimes, I think. So they don't become immune from the method your using. Just pay special attention to those undersides of the leaves.
TBH, I think the garden hose should be your best friend in that setting, blasting those undersides. Especially if the plant is easy to take out of the house, and can be done outside, then simply bring it back into the greenhouse. Separated, from plant, easy peasy, lemon squeezy... You want to get this thing sorted and under control before you get too far along.
Otherwise, it appears to me some possible heat stress going on there, or something along those lines. Looking at that top cola, looks funny to me, like you were in the heat wave or something. (are those fox tails?) Maybe try to do what you can to control the temps inside that greenhouse, from getting over heated.
Yea, I'm getting older also, not quite that yet, but in my mid 50's and life isn't what it used to be anymore. Got to take some precautions.
