Hammerhead

I recently switched hydro systems to a diy aero flo ripoff (with a twist or two) and was wondering if anyone like me was trying to run a perpetual grow using an aeroflo type system that will contain rails with plants at different stages running off the same res,( I intend to move one 3 site rail in every 3 weeks while moving one out and chopping). I ran into a problem right off which is not really the fact that the rails should be running at different nutrient levels but the fact that the additives I use (AN big bud and overdrive mainly) call for certain weeks in the cycle that they are to be used, this is kinda impossible to follow if I intend to move a new rail in every 3 weeks. So I've found AN hammerhead and bought a liter , just changed res tonite and added it, My question is, has anyone dealt with this situation and if so what was the solution?
At this point I just intend to run several additives but less of each. I'm not even gonna bother with which week I use this or which week I use that. Since I'll only be using hammerhead and big bud.

I don't think there's a way around it if they're all sharing out of the same reservoir, even
without running the additives. Why not simply move to smaller reservoirs and break
things down?

I run a vertical version of diy aeroflo style in perpetual style and the only way I can do
this is with redundancy in having multiple smaller systems. I'm sure it could be pulled
off without but you're either going to burn, stress, or not give the plants what they all
want when they want it.

If you're running hammerhead you should look into running mother of all bloom in conjunction
with it. There's a lot of people that are a fan of this bud booster combo, and for good reason.

Hey dis, thanks for the reply.The main reason I can't run individual res (although I actually can, thats a feature I built into this system)is because I also run a chiller and my res is a huge igloo cooler, during the build I did almost build in a feature that would allow me a couple seperate res (5 gallon buckets with pumps and plumbed) that would actually sit in the main res (big ass cooler) and whatever I put in the 5 gallon buckets would be cooled by the surrounding water running from the chiller.....but.... fuck that , my thing became complicated enough, one thing I could do is run the same nutrient but have a seperate pump feeding each rail with its own seperate (90 dollar) cycle timer. That way at least feeding could be controlled for each rail and each rail will have the same age plants in it.

If you have a chiller you could try running individual wort chillers. I've considered
that option myself but running a chiller for me isn't necessary in Co.

BTW, there's decent cheap cycle timers on ebay that work great. Even with an extra
on hand for in case purposes it's still half the price for a single.

I use only titan cycle timers, I bought a C.A.P. and ended up returning it because it had some sort of glitch that damn near killed my shit because the pump didn't come on overnight. Titan apollo 12 are the shit. I bought the chiller knowing summer is right around the corner and I really really don't wanna run the portable ac this year so I'm settling for high room temps running co2 and controlling water temps with the chiller, in reality if I kept the room at the proper temp of 70f or so the water temps would be fine IF I didn't have fairly large pumps in the igloo cooler res. I cycle the one feeding the sprayer heads in the rails just because its 290 watt and I like my roots to dry out a little between sprayings and it never hurts to use a little less electric. chances are I'll have to use the portable ac but I'll still only cool it down to 85 or so, my first grow I had no cooling or exhaust, room temps got to 0ver 100 f , water temps not far behind, h202 and co2 got me thru it.

although thanks for the link, those would be nice to have around and I could buy like 4 for the price of one titan.
