Hi Ive got 3 auto cherry bombs and 1 northern auto and they are a really light colour in the middles the cherry bombs are about 3 days old and the northern auto is about 7 days old I'm using a 50/50 mix of canna coco and perlite, I use a 2200ml or 2.2 litre container to mix my nutes of which I use 1.5 ml of canna coco A and 1.5 ml of canna coco B and also 1.5ml of canna cal mag. I use a ph tester and ppm tester and my ph is 5.8 with a ppm reading of around 420-425. So what I'd like to know is am I using too much or too little nutes? I will add photos of each plant in the next hour.
