as you can see there is yellowing of the leaves and browning of the leaf tips. thought it was an Mg problem so i added epsom salt to my water. seems to be helping but still not fixed. I'm thinking it might be Ca thats the problem seeing how there is no Ca in the nutes i am putting in.

now that i think about it, there might be Ca already in the water, due to the fact that i'm using tap water. the only other think thats not in the nutes i'm adding is sulfur. perhaps its that??
