I'd try something light for a week and see how they react. If you test your nutes with a meter, I'd go for 500-600 ppm. If you're guessing, try 1/4 to 1/3 of manufacturers recommendation. Give them pH'd water after a couple of feedings with the lighter solution. How about pH? I like it around 5.9 - 6.1 for a primarily sativa strain. Did you start these girls from seed?

BTW - when I always start counting from the day they go to 12/12, not when flowers begin to appear. The SLH bud above was in week 8, somewhere around 54 days or so, the VK was at 61 days. I also have a bit more light than you do, probably a factor for you as well. Not sure how large your space is, but if you could manage a single 600 watt HPS down the road you'd have much better results in terms of the density of your flowers.

I've never done a pure sativa, and you're right, they are said to be challenging. I understand the major issue to watch for is salt buildup resulting from the long flowering periods. Since you've been flushing, you should be good. Check out Washougal Wonders thread on the Thai he's growing, you might pick up a pointer or two there as well.

Farmer Rich Reviewed by Farmer Rich on . SSH 15 weeks and I find out shes prego!!! I dunno hows this happened. I dont see any sacs on the buds they dont look hermie. Could it have been from pollen from a previous grow in the grow tent? I cut a little bud tonight to test the smokeI ground it up and took a look with my 30x to find little bitty i mean tiny seed looking things..These things are tiny and im at 15 freakin weeks how many weeks do seeds take to fully develop? This is such a huge let down with such a sativa dominent strain...im losing it and now my little stoner Rating: 5
