The past week they really took off on growth. Had to increase water from .33 gal to .5 gal due to very low humidity. Speaking of which, I ordered an AC Infinity humidifier. She be shipped after 10/31. I do like that it has a probe so it will automatically turn off. I did find a caterpillar on one plant but I'm guessing it came from the drying flowers from my outdoor grow. I use the same room for drying. It caused some leaf damage but not too bad. After this week I'm switching to the flowering light schedule that will have more red and less blue. This will begin on week 5. I'll also start to add bloom nutes at 25%. Any thoughts on this?
