Calmag excess or defiency??

Royalgorillaxxstarted grow question 4 years ago

So.. I have 4 flowering plants. I feed them the same stuff. Same quantity. 2 out of 4 showed some signs on the older eaves and i was wondering if its an excess or a defiency. Yellow with brown spots. Not a wind damage for sure.

CRiSPrGrowanswered grow question 4 years ago

it's due to ph fluctuations, let me guess : you dont vigorously shake your feed after each pot ? so the two in the back get the bottom and the two in the front get the top of the feed, so depending on what you're feeding something like Rhizotonic or kelp based extracts will mess with the pH. Hope this helps ! 🚀

Deficiency?? Excess? Neither?Grown this strain before and had the same issue.. not sure if its a CalMag deficiency entirely. pH has remained at 6.0-6.5 or so in soil and didnt show signs until recently, seemed to have worsened after just two days of only CalMag and Ro water so I bumped up the bloom nutes.
