thanks for all the help. Im on 18/6. I usually water about 10 tablespoons every 2 days, water doesnt even get close to soaking through the bottom. I stick about an inch down and there is barely any water, it doesnt last in the soil very long. Would underwatering be a concern? Because its showing signs of overwatering..?
Good Lord man, water the dam thing. You're killing the root system. In fact by now you've probably got so many dry zones in the soil that they probably won't easily re-wet.
What you need to do is set it in the sink or tub and then get a gallon of water, put a few drops of Ivory dish soap in it and then slowly pour the whole gallon on that plant and let it drain thru. And then keep it moist never letting it dry back out.
That plant is not showing signs of over watering. Nor does it have a Mg deficency. If any thing it's got a poor root system because roots won't grow out into dry soil. And if you don't have a good root system it won't matter how many nutes are in the soil the plant won't get them.
Right now that's not a bad looking little plant but if you don't develope a good root system to support it, it won't turn out very good no matter what else you give it. The vegatative stage (which you're in the first part of) is where the plant builds most of it's root system. But it can't do that unless all the soil in the pot stays moist.
What are you using for potting soil?
