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.
Dude, you should document more often, maybe daily if you can manage. This is a big plant. Congratulations, honestly =)
You should defoliate. It will expose the lower buds sites to the light and you will have more buds.
Colour is looking good. Keep feeding what you're feeding. Don't increase the veg nutrients now until flower otherwise you may get nitrogen or nutrient burn. Once it switches into flower, give it just pH water and then the next water you can keep feeding until a week before harvest. Good luck. Hopefully it will be big =)
