Sensi Amnesia Autoflower test

my first growing test: The plants have a start for the 5th weeks for life. I built a simple grow room what's 110cm x 110cm x 200cm and I use mixed soil for my plants. I gave too much water and nutrients for them in the last week that's why they have another two days without water. I use Ion-exchanged water with Kristalon Gold nutrients and sometimes supplementary nutrients what's on the pictures. The bigger plants are 25cm height and the smaller plants are 22cm.
