This is my first indoor grow and I'm very much want to get this right.
As you can see from the pics, there is some minor damage on a couple of the leaves which I suspect is from heat or low humidity.There are no signs of any pests. I'm running a 400W HPS in an air-cooled reflector. Temps with the light on range from 78 - 82F and humidity is from 20 - 30%Rh with a humidifier going full tilt (I live in the high desert). Should I worry about this?
Another question: Are these still considered seedlings? I'm trying to judge nutrient requirements. I'm using Botanicare Pure Blend Pro Grow 3-2-4. PPMs are at 600. Ph at 5.8. I'm trying to follow the manufacurer's feed chart which shows increasing nute levels going from seedling to veg, but I'm not sure where I should be. From reading forum postings, it seems to me that experienced gardeners tend to judge nutrient levels by leaf color. Advice would be greatly appreciated.
I'm also wondering when I can begin topping. I'm limited to four flowering plants so I want them to be bushy.
Thanks!
