Another thought and forgive me if this sounds harsh......it seems to me that when you've improvised things its gotten you into trouble. (rainwater etc....) If I were you, I would look at the directions printed on the back of your bottle and stick to them.....although using nutes at the same ratio but less total e.c. usually works best imo.

Think about this: 1. You just paid good money for those nutes. Wouldn't it be wise to use them the correct way?

2. Who wants you to get the best out of their product? The people who made it. So it makes sense that they are going to tell you the best way to use it. (see.....they want you to buy their product again......)

I strongly suggest you try NOT adding your own ideas here and see if that works.

Good luck.

Again....apologies if that sounds harsh but your "improvements" here just aren't working.
