I used 1 ml of cal-mag and 1 teaspoon of grow big in a gallon of water and here's a pic of the whole plant. Did I read correctly that cal-mag can cause nutrient lockout?
PH is at 6.6, it's in a 3 gal pot, currently on day 33 I fed for the first time on day 30 when I started seeing a little yellowing and it's progressed worse. I have what I used written down but I'm not with my journal at the moment
This is my second attempt at growing a purple punch auto from barney's farm. The first grow I had a super bad yellowing problem that made me harvest early. This time I did some research got some cal-mag and a pH soil tester (not a cheap one) but this plant seems to be yellowing too so I'm not...
