Damn, PH was my issue before i got my auto seeds in the mail i was failing at peppers seeds and bagweed seeds. my ph was way to high, I'm happy i learned that before i wasted some seeds i bought.This is only my second grow but I started topping from the start because i wanted to keep my plant short in the tent. I read some info on other forums that wasnt entirely accurate and I learned through AFN what I can do next time to improve my grow. I hate to waste things and I wanted a chance to work on my LST so I let it go to see where it ends up.
I'm aiming to be around the numbers on the chart below for VPD. I just switched to flowering so the tent sits at 48%rh and 72°F during lights on. Going off the calculator posted by wildbill, I'm not that far off the target number.

Ya, from what I gathered your are correct. The PAR meter reads the 200-300 beyond the either side of the limits of the LUX (furthest red and furthest blue). I bought the LUX meter because I didnt want to drop the money on the PAR. I ended up buying both. I was worried I burned my last plant so I wanted to be sure not to screw that up this time. Little that I know, it was a pH issue that plagued my last grow.

but now you have good equipment to keep your plants happy so it all worked out.
I'm new so i thought the same thing about the plant being to tall but after watching grow journals I've come to learn some auto strains will just be short and bushy or just short and puny. The high yielding giant trees of autos are in a super auto group i guess.
