Oh for goodness sake, please start a diary! There are so many things this could be the result of and we need more information in order to help you! What nutes are you using? How old is she? This looks like it could be a zinc deficiency ... how are you measuring the PH? The problem is we don't have a diary and, tbh, even if you give answers to our questions HERE, we probably aren't going to come back to see if you've answered them... the diary is crucial! Start a diary, join the community - we really DO want to help!
