simple question i think ( reposted )

Im growing 10 ice plants 4 weeks old ( seeds from nirvana shop ) in 10 5 gallon grow bags with good soil with lime for ph and co op fungus for roots no added nutes. I have 2 400 watt hps / mh ( mh in their now im vegging ) and i am using maxigrow ( veg ) and maxi bloom ( flower ) 1 part dry nutes for flowering and vegging. I have a feed chart and a ppm meter so i can get the nutes right and this is my 4th grow so i have some grow experience but im definitly still learning.

with that info out of the way my question is how often should i be feeding my plants and how much water should i be using per plant ( taking into acount i have the 5 gallon grow container ) . i am currently feeding every 3rd watering and i water about 3 times a week spliting around a gallon and a half of water between the plants per watering does this sound right or could someone shed some light on this for me because this was just a shot in the dark / learning from my last 3 grows and from some of the 100 + gram budds i see on here i could use improvement ( i know i can't expect buds that big from soil esp indoors with these shorter plants but i will be setting up my hydro SOG once i have a suitable mother so time will tell )

here are some atached pics of how they look from my current watering / feeding cycle

seriously no comment on this ?

all i can tell you is what I do/done when checking you moisture stick your finger in 2-3" when you come up dry water and water well I water very slow and water til I get some run off. as far as nutes I think the plant will tell you when you are over feeding. I start at 1/4 mix and build up to full mix and feed everytime I water unless the plant says enough. then back off so far no problems But I also flush every3-4 weeks with my set up. I use tap water and adjust ph so I fear salt build up for a 5 gal pot I fush with 10 gal r o water ph at 6. seems to work my soil ph nevergoes above 7.2
