Good idea on both counts :thumbsup:

You're growing in soil, right? The ph buffer in your soil may be running out, and causing your ph to drop. I think the canoeing of the leaves is more of a ph issue, while burnt leaf tips is over-fert... but this is really just a stab in the dark without pics and more info... get back to us once you've found out the ph going in and coming out.
