Hulkberry/Blueberry ghost OG/THC BBuster

Day 71: Nothing to report. Day 72 : I cut several leaves (...) as I think at least 2 plants got some septoriosis ( THC bunker buster and maybe Hulkberry 2). When the light is off, I'll spray the inductor F. Day 73: Watering 2 L /plant for all plants but THC bb 's adding Inductor R (2 ml/ L) ( but no Bloom A+B neither than Elycitor. I think they had enough for a while and notice a tendency to overfeed that I have to refrain). Buds got and are getting denser/more firm (thank you blooming H). I sprayed the inductor F yesterday, watered R today and within 4/5 days, there should be 2/3 times more trichomes on the plants... Day 74: I changed the watering water for mountain source water with very low "bad" minerals, it looks like the watered plants liked it ! Trichomes have grown a lot on the space of 2 days although it's still hard to see it on pictures. More number than size but it still has to work for a few days. Day 75: Watering 2 L with inductor R for THC BB #1. Inductor R 's effects are now much more visible. I'll check again for the 2 coming days. You can't see much of Hulkberry 1. Lots is hidden under leaves. Hulkberry's are taking more time to ripen but we'll see the buds at the end. Day 76: Bought and installed and air intractor and an oscillating fan: After connecting the carbon filter to the cool tube ( today was warmer than the last days), T° quickly rose to 28°C +. My extractor extracts 430 M3/h and it's a little not enough with the HPS 600 W. Before spending another 300 bucks buying a 800M3/h, my growshop advised the small investment in the air intractor. I had not much time to test it before the light is off: T° was at 26.2°C but I'm not sure it wouldn't have rose more with a little more time. I'll check tomorrow. If it's not ok, I'll disconnect the carbon filter until monday and purchase a 800M3 extractor :( Day 77: Connecting the carbon filter T° may rise a little too much. The smell is not too heavy so I won"t connect the carbon filter for now and use some ONA instead. In a few days T° will lower and It should be possible to connect the carbon filter. If not I'll purchase a new extractor ( but can't presently move things easily (if I can) because of the scrog). At the worse, I'll change the 600 W HPS for a 400 W. Watering for all plants but THC BB #1, 2 liters +/- and no nutrients again. Tomorrow I'll spray Blooming H once again and for the last time.
