i have a 3by3 with a 600 hps 18 inches above how many watt per sq ft is that i suck at math

3x3= 9 sq. ft
So you're running 66.6w/sq.ft.
You'll see great results if everything else is dialed in.

Yes I do have a PPM meter now.
How do I use it to its full advantage? Do I calculate PPM each time I put individual nutes into the water?

It has a ton of great advice on feeding, lighting and everything else.
It's a big help with answers to those kinds of questions.

At that time I actually didn’t know about PPM until I passed thru a thread. Once I understood a little I began testing out but can never reach high PPM in nutes even after mixing in over the amounts in my schedule. I fed extra bloom.

But as far as progression, it started out worst, then it stopped a little. Now it’s back again.
I’ve also been removing those dead leaves that are already more than 50% brown.

Too much P/K can stunt flower development rather than promote it.

Feed a balanced feed throughout the plants life cycle. Just because a plant is in bloom doesn't mean that adding more BLOOM nutrients will enhance flower size. You can cause issues that will inhibit flower growth rather than promote it.

If you're going to add additional P/K you want to do it 4-5 weeks into flower and only for a few feedings. Then back to a normal balanced feed that includes nitrogen.

Regardless of what many apparently believe. Nitrogen is essential in flowering. Too many seem to go out of there way to avoid feeding nitrogen during the flowering part of a cannabis plants life. Nitrogen is used by the plant during flowering as well as P/K. Balance out what you're feeding and your plant will do great.

Good luck.
