In that one picture look like the plants is a little thirsty?
Your gonna need some close up if were gonna help.
That last picture look like your ready for something but I can't go into it on here!
 
ive tried keeping ph as close to 6.5, although i could and probably should invest in a better ph tester.

if this is calcium def is my ph too high or low?

The best pH levels for growing cannabis is 5.5. Cannabis plants like to be on the slightly acidic side. If your pH levels or too far off either up or down you will suffer nutrient lock out, which means certain trace elements will not be available to your plant. There is an excellent video on the homegrown hydroponics website that talks about setting your pH levels and is extremely useful for the new grower.

Here one answer I found. Looks like you need to lower your ph a little.

Soil pH Levels

Any pH level between 6 and 7 is fine but you should aim for as close to 6.5 as possible.

This is from Green Man. It is my Bible.
I grow organic soil mix and don't worry about ph level ever.
Thanks for the better pictures. It looks to me like a water problem.

Only water once every two days around the time when the lights come on.
To discover when to water, feel the soil with your finger. if you feel moisture in the soil, you can wait a day or two to water. The soil near the top of the pot is always drier than the soil further down. You can drown your plant just as easily as you can let it get too dry and it is more likely to survive a dry spell than it is to survive a torrential flood. Water the plants well when you water and don't water them at all when they don't need it.
Good Luck!

Well I hate to say it cause it's going to junks it but I haven't had soil problems in years.
Now watering problems is a different thing!

Lift your plant. Does it feel light or heavy compared to a pot with just dry soil in it?
If it's light or medium you can water it.

what kind of soil are you using? anything that already contains nutes? if so you just need to continue to water... i def agree with using the pots weight as a judge of whether or not to water... and as far as your ph goes it is def important and maybe this chart can help you some...
