Not too much to report. The Pineapple Express seed took a few days longer to pop so is a little behind the others and sadly the GSC seed never germinated so I used a free Purple Kush auto about a week after the rest. I have these in a smaller tent with a my new TS600. I followed the light distance guidelines and set the light 24 inches above the seedlings but got a lot of stretching, after moving the light to 16 inches that seemed to solve the issue.

Yours grow ten is not enough for 4 strains, maximum two. Also light is too weak( . I hope are going to buy tent with larger dimensions. And l lights too. For 4 bushes is good tent 2*5 foots. Have a nice grow.
@leondovych, Hey dude, Thanks for the advice. I've grown 4 autos in the 3x3 tent and Mars Hydro ts1000 before and had good results. If it gets too crowded I can split them across two tents.
