First Grow ever, Random Seeds

Finally moved #1 from its 1L pot into an 8L fabric as well as topping #1 & #2 on day 33 above the 5th node. The timing was alright I guess, the roots were starting to fill the bottom of the pot on #1. Applied some Dynomyco in the process of moving #1. Also removed lowest leaf pair on all plants. Number 2# is really gaining height now, its almost 30cm while the other two are at 20cm. Putting in Nutrients only every second watering. #1's leaves are such a juicy dark green that I am more worried about adding too much Nitrogen. The GCxSolo2 is running on 100% by the end of this week. It's getting tough to get equal light to the 3 plants in the tent with the bar, but I rotate them 90° once or twice a day and they are growing kinda straight. Also had to steadily move up the light to keep it between 28-35cm from the plants Had a little problem with Sciaridae but got them under control pretty quick with yellow stickers and Steinernema feltiae nematodes. #3 will remain untopped as it is about a week in growth behind #1&2. Also I am pretty sure at this point that #1 and #3 are of similar heritage (at least they look and grow very similar) and it will be a nice to see how they each perferom with and without topping. IF they turn out to be female, since I have no idea what I am working with😅 #1 and #3 are growing so bushy and with such broad leaves that I started to weave the lower branches through the big fanleaves above them on day 40. #2 on the other hand has thinner leaves and more space between nodes, so light penetration is no problem here.
