Utopia Haze on coco under LED

This week I tied the girls up, bending and shaping their grow. I also topped them for the second time. Day 29: first LST. Both plants had two grow tips and I bended them both to the sides, like a wishbone. Carefully and not the maximum possible amount. From this day on, I bended them a little further every day. I also removed the 2 lowest pairs of leaves, because they were lying on the substrate most of the time. I left all other leaves on the plants, to power the growth of the small grow tips. Day 30: second topping. There was now enough space between the 3rd and 4th nodes, hence it was time for their second topping. After the second topping, every plant has 4 main cola’s and all the lower grow tips were already removed. The 4 leftovers on each plant were tiny, but they started to develop almost immediately. A few days later, I noticed one or two grow tips developing on lower nodes, which I had already removed. I was wondering what would happen if you remove all the grow tips from the plant: I think I have my answer. Life always finds a way. Day 34: the tiny grow tips grew and their stems became long enough to bend them down. This young growth is still very flexible and easy to bend almost horizontally. This week, I reduced the amount of the FloraTrio Gro compartment in the fertigation mix, as the plants were showing signs of N excess. I also reduced the EC of the feeding mix (to 1.1 instead of 1.3). This seemed to have a positive impact, as the plants were less droopy this week and especially Lisa started to look much better. Also, I noticed the girls started to drink a lot more. The pots dried out a lot faster this week. However, today the plants were quite droopy again. I lifted the pots and was able to look under the pot, which is just some kind of raster. There were roots poking through all over the raster. The roots have colonized the whole pot. Hence, I’m pretty sure a lack of oxygen due to the size of the pots, is not a big issue anymore, the droopiness has something to do with the overfeeding. Since the roots are well developed, I’ll throw the root stimulator out of the fertigation mix. There is some N in it and I’m worried it might be over the expiration date. It’s an organic supplement and the bottle has been open for over 8 months. Runoff EC is at 0.8-0.9 and runoff pH is around 5.9, so there’s no problem there. All-in-all: this strain seem to require less nutrients, especially less N, which is common for sativa’s. Last, both plants already show a preflower here and there: pistils! They are definitly girls. Thanks for stopping by and keep growing!
