oohhhhhhhhh.....i <3 mh...
i am sorry, i cant say much about your lighting, i dont know how much space you have or how many plants....
i would just keep feeding every other day.....check your ph and adjust to what it needs continually, it can change from meal to meal for the plants...why would you water inbetween? every other day should be sufficient i would think..esp with your temps.........but that is just me, and how i grow.....everyone does it different, and you will find over time what works best for you...i hope this has helped some....good luck....

Thanks Princess, I thought I read somewhere that you should alternate water and feedings to avoid salt build up in the soil??
I have 8 plants grown from seed in a cabinet aprox. 3.5' X 2.d X 5' tall.

unless you have a long term commitment such as a older momma, and you also have water that is very high in salt content (all municpal water systems use some type of treatment that removes the salt - R.O, resin beds, etc...).
Most growers (99.999%) will never see any issues with salinity as it occurs here in California's central Valley when the apply irrigation water over a number of years - 30-50+ of water with crappy water.
Most our us change soil every grow cycle, so I really doubt that this could be a problem. What central valley farmers to here is to apply large amounts of water which drives the salt deep down into the soil below the root zone. There really is no viable way of removing the salt, so they just live with it.:wtf:

The water in the Central Valley is actually quite good.

I was in the engineering department at Cal Poly SLO and we did numerous projects to work on these issues. The only problem with putting the leach lines in the field that that it's a very expensive project, then what do you do with the drain water? In many area's it has soooo much salitinity as metals that it cannot be discharged into regular waterways so then you got another problem.... There's no easy cheap fix for these issues.
Putting this water into central ponds for evaporation is another nightmare....... Maybe we could put it into mason jars and send it to the adminstration for them to wash their cars with? Now there's an idea!!!!! LOL!!! I could see Chaney out there with Mr. Miagi - "ok Mr. Vice President, it's wax on with the right hand and wax off with the left hand....."

Salinity like, ocean bed salt/saltwater inclusion into wells/ road salt runoff, is rarely a problem for growers except in very specific areas.
However, 'salts' are not just Sodium chloride, Calcium chloride, or Calcium-Magnesium Acetate (all common road deicers that you will have to contend with if you grow near a highway that gets salted).
Salt buildup can be a problem in pots in as little as a few weeks if you are:
-Feeding aggressively
-Using pre-ferted soil
-Your tap water has an unusually high mineral content
-Using shitty fertilizer that does not contain adequate chelating agents
-Any combination of the above
Just one more reason to use good quality fertilizer! And flush at the first sign of combo burn/def = LOCK OUT!!!
