FastBuds GreenCrack x6 SuperSoilStyle

Wow! What a difference a week makes with @FastBuds. Day 28 and the super soil seems to be living up to it's name. Hopefully it will hold out until the end without any top dressing. Growth has been explosive and it seems everyone has doubled in size. Last time I really measured, or notated, was on the 18th at 4 to 8 inches. This week the range is 18 to 27 inches. All have shown to be female except GC#3 and Tangie, nothing yet. And none have started flowering. Color is gorgeous and no signs of deficiency. I had to raise the light because they are growing so fast they were showing signs (taco and saw-toothed) of heat stress. I think I may need all 8' 6" of ceiling height for this grow. Right now the light is about 42 inches from the kolas and 46 or so from the canopy. Everybody is getting fed 1/2 gallon RO water with a little CalMag (4ml), brown sugar (1/2 tsp) and Epsom salt (1/2 tsp)/ gallon every other day. GC #3 is an impressive looking plant. Her structure is solid and symmetrical and has started putting out some 9 fingered leaves (#5 has too) but hasn't shown any signs of sex. GC #1 and #4 have pretty much been cast to the side and replaced by a couple seedlings going into hempy buckets (separate diary). I haven't been doing a whole lot with them because they basically stopped growing. I topped #1 after the 4th node just to see if anything would happen and what do ya know, she started growing a couple new tops... LOL. And #4 started back again too. But they are getting in the way and I will be removing them once I know the hempy's are going to make it going forward, couple more days. Anyway, that's about it for this week, looking forward to the next couple weeks, should be busy with the start of flowering and figuring out how I'm gonna handle this grow, it is getting large. Thanks for tuning in and turning on. All questions or comments are welcome. Peace
