First Grow Cookies Gelato Auto and Sweet Zz Auto

In week 2 not much changed. The weather was very hot in the past week and its up to 29 degrece Celsius in my tent but the plants take the heat quite well. The Sweet Zz plants seem to have entered veg phase and are growing fast and strong. The Cookies Gelato plants are growing much slower but at least Cookies Gelato 1 seems to be making it to veg phase slowly. All Gelato plants have these light green stripes on the leaves and they are also weird shaped. I don’t know if its bad genetics or something I am doing wrong. On day 12 I decided to feed Sweet Zz 1 with 1ml of biobizz bioheaven and 2ml of biobizz root juice. I spectated the plant closely the following days and she seems to do fine. I am thinking about start feeding Sweet Zz 2 and Cookies Gelato 1 soon. On day 14 I decided to turn up the light in my tent to around 40% power and tried to measure LUX which now sits at around 17.000 LUX on top of my plants. I keep an eye on and changes which Night occur. I don’t know if i should top SweetZz 1 because i read mixed opinions about topping autoflowers. Maybe it would be smarter to start doing some LST. If anyone could give me some advice I would really appreciate it.
