Day 25: This week the growth has really started to take off. They are growing upwards and sending out a lot of branches. 2 of the plants are clearly different from the other 2. Why? Maybe because they are 2 different phenotypes, maybe they really did have thrips like I thought and this stunted them, maybe their roots were outcompeted in the pot, I'm not sure. Anyway, it's interesting to watch. 2 are very small with lighter colored leaves, and if I had only grown 1 plant and it turned out like that I would have been disappointed. The other 2, however, are growing nicely with darker green leaves.
I thought that having 4 plants in the pot would get out of control, but so far it's been okay. I know they still have another 2 weeks of stretching to go, so we'll see what happens. It looks like the yield should be decent.
I watered 2 times with 1 liter of water, not wanting to overwater again. Then I watered 2L again the last time, since the pot was light already. I added biobizz bio grow and acti vera to each watering.
I continued to do a little LST by bending the main stem down and away from the center. The side branches I have only pushed down with my hands for the moment. Soon I'll probably tie them down too.
I haven't sprayed the plant recently, so I'll do that during lights off.
At the end of the week I watered 2L again and did some lst on a few side branches. The tallest plant is 30cm tall after doing lst. I can see the first white pistils appearing now.
Looking good, I need to get to the point where i can say "2 more weeks" confidently. Its more of a guessing game with the plants I've grown so far as there has never been enough really clear trichome changes, even harder to see on these purple varieties.
@eurorack, Thanks a lot! Just because I can say it confidently doesn't mean I'm right ;) There are other factors that also let me know that the plants are almost ready. They start to drink less water than before. Some of the fan leaves fade yellow/purple and some fall off. The pistils curl and darken. And the trichomes change as you mentioned.
