Ok, I just added some of the Tiger Bloom last night, at half of the weak strength without refilling the res. I figure that since I'm already running the solution weak in order to be safe, it won't hurt to just add some bloom nutes. I'll keep an eye out for nutrient burn, I know what that looks like as I burned my soil plant a bit a few days ago and had to do a flush. I'll keep an eye on the new growth to see what happens and keep you posted. The roots are still doing great and growing like crazy!
