Ok so i have 4 plants growing in FFOF that are experiencing a pretty bad zinc def from too high PH. They are in week 6 of flower and the top of some of the nugs are turning white from the def. I put in ph 6.5 water and out comes water with a ph of near 8. obviously my soil ph is too high so i added some sawdust to try to bring it down with no results. What do I do? My tap water is about 7.5 and i have been using lemon juice to lower the ph. I need to save my harvest. Please help!!
