I was using Pro mix. It is a non soil growing medium. And was having a lot of problems and small yields. Was pointed in the right direction by another thread that I post it on here, that I needed to add calcium to my water as no calcium was going into my plants that I had a deficiency. Now I'm doing that so what I've been doing is adding half the required amount from my calcium supplement to my Waters, and my nutrients. So they pretty much get half the amount of calcium every feed that is required on the bottle. Now I usually on day one I would feed 3/4 of the strength of regular fertilizer that it recommends. Day to it'll get that diluted with 50% water. Day three straight water day 4 probably no water at all and let the soil dry out a bit. Now my water is usually pH to about 6.2 to 6.8. Definitely in that range. I am using good quality fertilizers and good quality growing mixture. Indoor grow in grow tents 4 by fours. With 1000 to 1200 watt LED lights. I know this is a bit of a story. Okay but now I have this problem, on some plants leaves are sort of tacoing? Sort of curling down in the tip assorted drooping a little bit now I definitely do not think it's over-watering. But not sure exactly what's going on here
