That's what I was saying. It looks like it's in too hot of soil that didn't have time to cook or he added the top dressing and it's causing issues. Locking out some nutes and having toxic amounts of other nutes. Looks like unbalanced soil.
At first I thought he said he didn't add anything and then it sounded like he did. I'm gonna wait until he answers my questions. Underwatering will also just make it worse, but I don't know how moist his soil is.
Just an FYI I just top dressed with gaia green, it takes about 2.5 weeks till the nutrients are available in the soil so its not because i top dressed, its because im using self watering trays that never over or under water in my experience, I just poured in to much water when I added the recharge.
The plant in question was well waterd by the wicks, the tray was filled up a little over half way and the gage that measures how much water is in the trays kinda sticks you have to flick them to see how much water is actually in the trays. I didn't know that at the time when I probably over waterd them.
Does that make any sense?
