I use a special method to get bloom nutes in there. They are at super high levels and the aquawater only supplements during bloom.

I use small tubing, which is drilled into the sides of the pots. The method is no secret but the tolerances are insane. I inject approximately 100 ml of high concentration organic bloom nutrients every 3 hours to each blooming plant via a separate 25 gallon container which has its own air pump.

Its automated and I fill the reservoir every week or so. The amounts have to be just right, I overshot it first and got nute burn and lockup on 1 plant. I dumbed it down and I had to experiment with the mixture for awhile. Now I get optimal ppm; in the lavarock itself where the roots are it reads around 1400 ppm bloom, and the water is around 750-800.

I'll post pics of the unit later, its rather simple but like I said its in the mixture, amounts, type, and intervals of delivery that make all the difference.:rastasmoke:
