I've been over-feeding it lately, noob mistake. Was using 20-10-10, half the recommended dose every watering.
Using Miracle Grow soil with 3 month time release.
Also another noob mistake. I didn't have a good pH tester, and i was watering my plants with water that had a pH of 2 for 2 weeks.
Watered last time with pH 8 to help conpensate, will water with 6.5 in the future.
God damn these plants are sturdy for survivng trough my stupidity.
Can't buy cal/mag. Going away for holidays, bringing plants with me.
