I never---EVER---mix nutes neat... Nor are they ever poured directly up to the roots. I actually unplug my pump to be sure that it doesn't come on during mixing, and balancing, even though I time my changes for 4 hours before it is due to come on again. So there's no way possible that any pure nutrient solution hit roots at all.
I usually set my pH at 5.9, so yeah it was a little off, but nothing to be really worried about. I did adjust it back up to 5.9 again after the last post. The beauty of BPN, is that **USUALLY** when I set it at 5.9 it's rock solid there every time I check it. I think I may go out tomorrow to my hydro shop with my pH pen and see if it's off the mark somehow. If it is, I'll report it here. It would sure be great to know it's the pen, and I don't have to up my dwindling year's supply of Bloom for the veg. Hell, I'm already using 100ml a pop in Flower in 2 reservoirs, so 200ml /2wk . . . yeah, saving Bloom for flower is my first goal (period). However, if I have to, I'll up it a few mils in Veg, so it's not like I won't do what's necessary.
Hey Corey.... Molybdenum? Thoughts?
