Thanks for the info @LabRat, @Meesh, and @Esrgood4u! Information is knowledge. All of this info will go into my memory banks. The chart is very helpful and will save me lots of calculations.
I’ve always read that when feeding nutes you should start at half the recommended dose but never thought to up the dose when the leaves start to get lime. At on time I read that the lighter color was the result of low Nitrogen levels and that Cal Mag would help. Never thought to just up the nutes.
Now that I have the meter I can start looking at increasing doses in a predictable way. I like the idea of increasing levels by 100 ppm at a time. On my first grow I went from 1/2 the recommended dose to 3/4. Now on this, my third grow, I have seen good growth and color just leaving it at half dose. I have a couple weeks more of feeding and will try increasing ppm a little. I like the idea of bigger, fatter bud!
