Instead of giving nutrients I gave only water because I noticed some yellow tips on the new growth.
The plant had been getting 700ppm feed(including 220ppm tap water). Nutrient buildup in soil?
I made the switch to 12/12 today. Since 2 days the new growth has been looking funky - the same corkscrewy thing I had in my first grow.
Overall, a lot of trimming, bending, training. It has become a cool plant in my opinion :)
Info useful for my question:
*6.2-6.4ph water every time
*giving water when the soil is dry and lower leaves start to hang a little. but i suspect it is hard to overwater with these airpots
*built up nutrients to about 720ppm until last watering
