Problem on first BB grow

Well this is my first medical grow and i have made lots of mistakes but i think i have learned from them and hopefully won't make them again.

Well here is my latest issue. What deficiency do people think this might be? I have looked through the problems links but not quite sure what it might be.
I thinking maybe a calcium or sulfur.

5g rec bubble buckets
marleys collie
600w hid
38L/min air pump for three buckets with ceramic micro pore stones.


PH 5.7-6.0
ppm 850 (.7 meter)
air temp 68-74 F
res temp 63-68 F

Nutrients
botanicare Pro blend grow
cal mag 5ml/gal
aqua shield
hygrozyme
I use RO water at 0ppm starting point.

Roots are white looking great and growing like crazy.
Leaves are green and the plant is growing like crazy just mutant leaves. I had a slime in my main res bucket because i forgot to turn on the air pump in there and that kind of slowed them for a few days that was over a week ago. Cleaned everything out and flushed when i first saw the slime everything has been looking clean since then.
When i first noticed this slime the leaves where starting to claw but roots looked great the whole time just slowed down for a few days.


ppm slowly drops ph slowly rises. So i am pretty sure it is not over fert already done that once.
I hope this info and the pictures (sorry for bad pics) might help someone help me out here.

Thanks

Your looking good. Your plants obviously had some shock from no oxygen being supplied to roots but if you caught it early enough you should be good and they should bounce back. What PPM level are you running but the nutes you have listed are pretty standard and quality products. I would say it would take 7-10 days for your girls to bounce back from 0 oxygen, but I have never starved my plants but usually it takes a week to get out of my shock period when I transplant / screw up or PH is off LOL

Weedler: Thanks for the help. My ppm are at about 850 on a .7 meter. I am doing a res change today and am going to up it a bit.

My max flower ppm level never exceeds 900. Some can run high ppm's others can't be careful

My first thought is to cut back on the cal-mag by 1/2 and move the Ph up to 6.5. I can't tell from the shots what shad of green your plants are but it does look to me like over feeding on the ca-mag. I use it all the time but @ 1/2 recommended. Too much will turn the plant deep dark green and that's bad.

If your pH is at 5.7 to 6.0 you are only using 70 to 80% of your nutrients.

Keeping pH at 6.5 to 7.0 is the optimum mobility range for the elements your plant needs.
