Trying to grow my first autoflower

Started low stress training on week 3. Has not been defoliated yet but I feel like it would be time. Also for a while it was probably too far from the light, because the branches started getting a bit tall. Moved the light a lil bit closer, hopefully it will solve the issue. Also almost basically ever since I started growing the plant the end of the leaves are drying, the reason for me is unclear. For a while I suspected, that it was too close to the light, but later figured out that suspicion was unfounded. Sofar humidity has been quite high, so Ifelt like it didn't need much watering. It received 0.75mll veg fert on 02.12. and about the same amount on 01.21. Im alternating watering with ferilizing, will increase fert. concentration next time.
