Other than searching out people who have down this- the only way you'll know for sure is to test it by running a couple plants at different ph levels. Always makes it harder to know what's going on once they get messed up leaves though.
I may have mentioned this before on this thread but I once did test run using two clones - one at 5.2 and one at 6.2, and the one on low ph was beautiful and quickly grew to twice the size of the high ph one, which had all kinds of problems.
I'm growing in sunshine mix (peat miss and perlite). I believe it has lime in it
It's normal for ph to rise in the pot, especially with lime, but even without. My runoff is usually about 6.7.
But unless your runoff is completely out of the range - its best to ignore it and just make sure that what goes in is at the correct ph. Whatever that may be.
