Canna coco -Blue Cheese & Sunset Sherbet

Week 4 flower : everything’s looking nice still got the lights about 7-9” from top of canopy without any issues . The humidity has gone up to 50% in day and I can’t really get it any lower I’ve already got a dehumidifier so don’t want to get another one . I would like to lower to 40-45% and lower for last 2 weeks but can’t see that happening . I’ve started the pk from end of week 4 (day 28 )at 1ml per litre this took my ec to 2.2 I will see how it goes and maybe up it to 1.2-1.5 and I’m going to use the pk for 7-14 days then I will start the flush I also lowered the silicone to 0.5ml per litre 3x blue cheese plants are on the left but has spread over and 1x sunset sherbet on the right
