So I have some Beautiful Strawberry Chemdogs(SCreme'N'Dawg) that I recently put into flower and a few are turning dark purple on the stems (my guess its its Phosphorus deficiency) and my guess why is because I water with RO water with Canna nutes (a+b, cannazym, calmag, Silica) at the Ph is around 5.6-5.9 but the run off is 6.3-6.5 .... What would cause the Ph to jump like that?!
Purple stems... Ph issues...
