Feel that the light intensity and lack of drainage caused the possible defiencies that appear to be by the leaves. I administered 50ml 6.5ph water and meigs grow fertilizer. Also, drilled hole through side of bottle for drainage . Will post pictures in a day or 2 to see if it perks up
You need jacket for bottle, roots hate light ..
They hate swamp too, so drain hole is a must ...
Good luck with this one, will be challenging with watering and heat ..
All the Best !
