Yeah I only saw that pic after I posted, the rust spots are definitely calcium though. If your ph is swinging like crazy that could be locking out things left and right, depending on how long it's staying at that level.

yeah I really hope I can fix the root problem with my tea brew..
I used wormcastings, molasses, plant magic essence and hydroguard

Then yes I believe it to be a ph issue, that's a big swing towards the alkaline side of things.
Once you're over 5.8 you're gonna lock out calcium, over 6 and potassium is out too which is what the 5th plant looks to be having issues with. Here's a chart to reference.
