http://www.horticulturesource.com/grodan-drip-cap-6-125-cs--p9927/Not gonna lie I might have to use the same exact thing caps, how much are these? Im about to use two watering spike per 7inx7in pot. Let me know of the caps are better then spikes. If so I might use some blumats vs watering spikes vs these caps on the next round and see what watering system is the best for my coco medium.
does the P seem a little low, and even the Mg in the formula?
I decided this grow to give the Veg+Bloom a try this go around and one thing that I have noticed is when I mix the Veg+Bloom in my reservoir the water is clear with no sediment on the bottom, but as time goes on there seems that some of the nutrients must migrate out of the water with time and settles on the bottom of the reservoir. I do a water change in my reservoir about every 5 days.
I have a reservoir that holds 7 gallons and last water change I had mixed the Veg+Bloom to a mixture of EC = 1.7 or 860 ppm.
I have two air stones and a small H2O pump to keep the water circulating in the reservoir
I'm running two plants using Blumats and air pots in a grow cabinet.
In the past I have ran GH Flora Micro and Bloom with the current setup for 5 grows so I know the system works, But this is the first time that I have used the pump in the system and this was added to help keep the powered nutes mixed.

So how is it working in comparison to the GH stuff you ran?
That sediment at the bottom is probably excess salts IMO.
