Help me find what it is

Hi i am 2 week in flower and i am exp droopy leaves and i see a flying tiny think in my grow room (gnat?).i grow in soil and i didn;t give any bloom yet so it is posiblly phosphorus def(i see red stems)?My temps is 83-86 f (27-30 c) lights on 50 rh and 70-71 f(20-21 c) lights off 60 rh.I have plenty airflow and dimmable balast that i am cosinder to bring it down a bit to fight high temps.
What do you think is my problem temps,phosphorus def,cal/mag or pest problem?As i say next feeding will hit them with bloom nutes for first time.The affected leaves is at the bottom of the plant.Note that i check my plants with microscope and i didn;t find any pests or eggs.

The plants are flowering. They need more nutrients. The deficiency looks like potassium deficiency, and they need more growth phase food, with higher N and K levels. And more magnesium, calcium and trace elements too.

Also, those pots seem small. You might want to repot the rootball into some light soil/perlite mix, and add a tablespoon of magnesium lime per gallon.

Which also goes to nutrient deficiencies. With a larger rootball, the plant can take up more nutrients.
