Multi-Strain Grow (first legal grow) (title edited)

Week Five we are in Week Five. I labeled the Plants from the random flowers I saved and popped, before any Seeds arrived. We have RNG 1#, which is the only one with purple stems, I guess its the genetics. no sex yet. growing fast. did some LST to spread out the branches. RNG 2# is the bushy one in the middle. no sex yet. I deleafed a bit and bent the main 2 stem from the top to the sides, so every sidebranch get light to grow up. RNG 3# is the first to show sex. it a female, so im very happy. she is the slowest of the 3 RNG, but I wish all are slower like her. also to some LST to spread the branches. The fastbuds try to catch up, but they are not there yet. I guess the push up till the end of this week. few cm to go. you can see some differences. so all in all, I think everything is still fine, the RNG 2# has burned tips, I guess from bad watering and buildup. I tried to better my watering. leafs looking fine and the growth is still nice. LST is going fine to aside from one mishap with RNG 1#. when re-adjusting I broke the main stem =( no big deal for me, because we have to wait till the fastbuds catched up. they are in week 3 now and they will start to explode soon (I hope). in this week I deleafed where the fan-leafs were blocking new growth and in the lower parts of the plants. its early for this, but I only have a small monkey fan and I want good air movement inside the plants. i pulled the light up to 50cm distance and put it on 70%. I plan to reduce the light cycle to 16/8 and up to 75-80% power soon and flip to flower as soon as possible. I did a light feeding with the 5:2:5 organic nutrients once, 1 liter divided to all plants, just to keep the soil alive. at the weekend I did a good watering and really take care the plants are watered right, did way too less watering in the beginning. then I corrected it by watering from below. after waiting 1 or 2 days, I did the right watering and now I wait till the soil dried up a bit. the uptake from the plants are very different, so it makes it hard for me to do it right as I am a beginner in growing. plan to get autopots in the future =) thanks for reading till the end and checking out my grow.
