No worries Mrbubbles. Ya I'm using tablespoons. Take a look at the ff feeding schedule and you'll see I'm actually using half the recommended dosage. Make sure your ph'ing your water after you add your nutes before your feeding your ladies. I've found that ff nutes really messes with the ph of water as will any nute. So just make sure you ph before feed. Also you might want to get ff sledgehammer, I strongly recommend using it, as dose ff, when using the trio. Best of luck!
