New cycle with fastbuds, growing sweets

Hello, people! I have the first serious troubles. Today in the morning befor the watering I’ve noticed a mold on the central cola of the plant 😕 The side with the mold is 100% mine. On Saturday I watered it with Flora Clean, 5-6l. Ppm became 1100. I made it in the evening, and I didn’t turn on the vents for blowing, so the humidity rose. This is the reason of mold. One shouldn’t do heavy watering in the peak stage of the flowering. It’s better to water in the morning, not too much. And at night you shouldn’t turn off the blowing. Immediately I ordered Phytosporin, 2.5ml per liter. I leave the vents on for the night. To decrease the humidity level I’ve put six bottles with salt inside the box. Maybe it’s stupid, but salt is very hydroscopic, and it absorbs moisture well. Our grannies put salt between the window frames so they wouldn’t weep in winter. I had to cut off the half of the cola. 70% of it was molded. I threw it away. The rest of it I put on the throttle to dry, in the evening I’ll taste it. The end of week: I haven’t noticed any other mold. I poured Flora clean two days ago. I wrote that it’s not recommended to do it in the flowering stage – the plant got molded. I had to cut the central cola. On Wednesday I watered all of them with Phytosporin M (2.5ml per liter). I don’t turn off the blowing at night. If it comes again, I’ll cut it again, but I hope for the best. On Thursday I’ve poured the soil with Cannabiogen Delta 9 5ml per liter.
