First Grow Wedding Cake + Skywalker OG

First week of flower stage is in progress. While turning the light cycle from 18/6 to 12/12 I gave all plants 31,25g of biobloom (250g/package divided by 8 plants). Additionally they received some water with 1g/l bioenhancer and 0,3ml/l calmag. 2 litres for 8 plants. A few days later I gave them another 100ml each without any fertilizers. One of the wedding cake plants was looking weak all the time, so I decided to kick her out of the tent. Because of the expected high temperatures during summer I put the lights on at night from 9pm to 9 am. The temperature and humidity is roughly at 25-26 degress Celsius and 49%-58%
