Wildwood Weed, My First Grow (3 Trees)

UPDATE #2 9/25/2020: Late this afternoon I added a 34 CFM little booster duct fan to push some air through the sprout/seedling/early veg portion of the tent (which is overall 32 sq ft. That makes the 34 CFM booster fan the ideal fit - and it is. No detectable heat after 3 hours' operation. So, you might ask, where is the exhaust from the little side of the tent going? I took some 4' duct I had sitting around and connected AIR OUT from the smaller tent to the 4' x 4' main tent. This is giving even better temperature control than before, and the 6" AC Infinity S6 is even supplementing the 34 CFM fan in the secondary tent. Just as planned! Now I have a good airflow for the next round of seed to cola growth. UPDATE 9/25/2020: I'll be damned if it doesn't look like they ALL gained about 1-1/2" since yesterday morning! I was following a feeding schedule from a well-known, well-versed Youtube grower ... and it didn't match the manufacturer's recommendations. So I went with what General Hydroponics recommended and ... well, you know. Growth. Lots of it. Week beginning 9/25/2020. With the replacement of the Giixer 1000W as the main light and the installation of two new grow lights, the tent now seems to be working just exactly as I keep reading it should. I've got fair control of temperature (nothing horribly out of bounds) and good control of humidity. I think I got good recommendations for the use of the General Hydroponics nutrients. Plant growth this last week has felt exponential. New lights (3-in-1 tent): Main 4x4' Grow Area: Mars-Hydro TSW-2000 (new model with easy dimmer control and hella chain-lighting control), 18" from the plant canopy, light dimmable, providing 961-731 PAR for various stages of the bloom cycle, plus it can easily be dimmed to simulate shade for the last 3 weeks. Upper Section (4'x1'x5') for Early/Mid Veg: Mars-Hydro TS 600W @16" from the canopy, providing ~500 PAR for the early/mid veg cycle. Bottom Section (4'x1'x3') for germination, sprouts, and seedlings: Giixer 1000W that is working itself to death to provide about 350 PAR for the sprout/seedling cycle, which I hear is just about right. I originally thought I'd be throwing the Giixer away because of its horrible PAR values at even 12", but ... those same 'horrible' PAR values (350s) are just about right for sprouts/seedlings. Other factors have been stunting the growth of the plants. Next week will have a full explanation. If I've done my math right - and I usually do - I should have a complete system from seed to flower that I can rotate through based on need. Plus CBD flower. And tomatoes (at some point)!!
