This week I noticed I'm starting to see what looks to be a cal mag issue. Leaves are starting to yellow a bit so I need to act fast. I assume I'm having this issue due to the fact I'm using ro water. I bought some organic cal mag and used some last night. She seems to be bouncing back already. Doing more lst and watering every other day with liquid seaweed molassas cal mag in ro water ph to 6.5.
