Lots have changed over the last few years growing. I kind of adapt as I go. 2 years ago when my 600 watt HPS crapped out on me I only had a 1000 watt to replace it, After seeing how well those plants packed on buds I never looked back and have been growing with just the 1000 watt lights. My first years with only 1000 watt lights is also the first years of Powdery Mildew. Everything has been a hassle since. So the last few crops I have been fighting other battles. I never did get a chance to really see what 1000 watts can do.
This year I am getting a idea. Part of my problem has been the explosive growth. I don't know that I have every found the perfect combination of light and nutrients. The lights are doing their part I just need to learn to feed them to continue that growth.
That is the thing about upgrading only part of your grow system. By adding tons more light I created a new environment that had new needs. If I hadn't had all the problems I should have noticed this before now. I didn't know it was one of my problems last year. Some of what I thought was because of PM might have just been the plant telling me it wanted more food. I was limited at first because of the product I used to control PM was a soil treatment. Now with floral and everything else solved different stuff is showing up.
Not that anything is going wrong now. All is good. That is why I can see that it was a problem. Even If I had shared all this in journals. I probably wouldn't have caught it. I never go back and read my stuff LOL. Learn as you grow folks.
