Does this calculation seem correct?
With the S6 bin at 200 watts, PPF is approx (4.84 x 200) = 968. Area of tent =5 sq ft.
Approximate PPFD is around 2000.

QER is 4,86, asuming 55% eff. 200w is ~110PAR/w x4,86= ~535μMol/s ppf or 535μMol/s/m² ppfd.
5sft = 0,467m² =~1145μMol/s/5sft., calculate 10-20% wall and distance loss in and you come close to 1000μMol/s ppfd.

Pics from yesterday.
Rather than feeding daily I just gave each pot an additional 32oz of feed and they seemed to perk right up. Also introduced the Mammoth p the last 2 feedings.
Will wait till week 6 or 7 to add in the blossom booster.
I'll snap some shots tmrw.
Same differences as before except the 90cri tent most definitely has some more stank creeping out when you unzip those doors. Same cuts, feed and everything.

Girls are starting to chunk up. That #1 is always hungry. I can't keep up with her. Last run for her. Have some new blood going for next round. Gonna do a side by side sog. Out of all my jars the sog buds outshine everything else. A little more upkeep but way less issues and better reward imo.
