Calcium lockout

It seems as though i continue to have some calcium deficiancy's with my grows. I always use sufficient CAL mag, and PHd water. I'M wondering if the actual water I use is the problem? I use spring water from my local Harris Teeter, and always ph it down. Can anyone help me with this?

PH going in is always between 6.2 and 6.5.. I use Happy Frog grow med. I have to admit, i dnt ph the water coming out
 
IF you are growing in coco, this is kind of expected. Coco needs double to triple calcium when it is first used.
 
I would check it coming out, if you keep increasing the Cal Mag but nothing's changing most likely lockout. pictures of the plant would help to make sure it's not something else. How much Cal Mag to a gallon? What size pot? How old are your plants?
 
Are you ph’ing the water before adding the nutes? Thats the way I read it..
if so, try adding nutes THEN worry about the ph.
 
Ok. i'm new to the site' still trying to figure out how to post pics..I'm adding 6ml of cal-mag per gallon in 3gal pots. The plants are at 7weeks..I'm trying to get this resolved before switching over to flower.

Nice looking setup rmyers555, you plant are coming along just need a little help.
It looks like you do have a magnesium deficiency( yellow in the margins) but I'm thinking a couple things could help the environment.

1).Your Leaf is drooping and curling this can be a root problem/watering problem, make sure you are letting the pots dry out but not going to long before watering and have good drainage. Soil does not need a lot of runoff and if you have been pushing a lot of runoff out the soil itself may be depleted of nutrients it started with. if you have been getting a lot of runoff and your coming out PH is way off a good flush to correct PH is a good idea (lockout) you will need to feed the girls at some point 3gl. Of happy frog isn't going to make it the grow. If you don't like/use some kind of fertilizer your yield can go down hill, I know that D.A.A.S.69 uses mostly just soil and unsulphured molasses through his grows so they is alternatives but I'd look at having some NPK on hand.
Do you have roots growing out the bottom of your pots? Does it take along time to dry out?

The droop can also be windburn (the fan under your plants can be the suspect) if they were my plants I'd take a couple fan leafs off in the middle of the plant to get air flow and move that fan up above the canopy. What's your temperature? High/low? How close/watts is your light.
 
Thanks Mr.furley, I water just till i get a descent , even leakedge. But it does take a little while for it to dry. Longer then usual.. Alomost 4 days.The fan below is to drive my co2 up. But i see where you going with that. But all fans go off on down time for 6 hours..18/6 with 3 plants in 3x3x5 tent with a HLG 300 Led fixture pushing 280 watts full spectrum.I have it about 24 inches above the canopy. Thats my new toy.Lol..The roots are not really growing out yet, but are visible.I'm transplanting fom 1 gallon to 5 gallon on my next grow i started. But these start and finish in the same pots. Temps stay about 85 right now, Not sure about temps when lights out. Gotta keep sealed with co2 but i think 85 is ok. Humidity around 60%..What type of water is best to flush with? And do i use cal-mag during flushing?? I bought some purified water, and was gonna use that. I was a little surprised how high in ph it is.. bout 8.0
