try to get your ph closer to 6.5. you might want to pick up some bottled nutes, or make a compost tea when it gets older. You might also want to transplant it.
I cant decide what is wrong with my plant. Can you guys? Yellow/ brow tips on middle leafs. and white/yellow leafs on the bottom part of the plant. There is roots organic soil with a small amount of extra nitr. and phos. mixed in the soil. I am going to trans plant into super soil soon
