Skipped one week of reporting due to personal reasons. Plants look so different though both is the same strain. Everything is identical, soil, nutrients, etc. Completed my final trimming for the first plant and probably won't be touching them anymore.
Feeding 1.5L every other day.
@backblt_aty, No problem, I'm happy to help, I had the same problem and I couldn't understand what it was. I switched from coconut to clay, which can't be watered like coconut. The second thing is that AUTO plants need much less water than regular ones. Try letting it dry out a bit, and give it maybe half the water it usually gets, I think you'll see it stand up nicely in time. Better less than more :).
