Eagle Scout First Time Grow

Plants have gotten extra bushy since they were topped last week. I’ve also expanded and upgraded my “swick” (self-wicking) watering system and plants seem to like it. It’s also less work for me. I just top water with compost tea once a week. I use a surface blumat which is attached to a 7 gallon tank. The plants drink as they please and when the surface blumat senses the water in my reservoir is getting low, it refills the reservoir automatically. The blumat cost $38 but I feel it was worth it, especially for this type of organic growing where living microbes prefer the moist soil. So far, it looks like 4 of my 5 plants are showing early pre-flowers. Again, this is my first grow so if you’d like to comment with your thoughts on what sex these plants might be, that would be super helpful! Looks like I might be outgrowing this small 2x2 tent and 600 watt LED soon.
