Hi
@DeeGee757! Well, it's a very good strategy since it's easier to fix a deficiency than to recover from a toxicity/nutrient-burn. That being said, you will need to be very careful about her first deficiency symptoms if you don't want to slow her down and want get the maximum yield. I bet she will start showing a slight yellowing discoloration and/or some yellowing between the veins, in the 1st scenario add some Nitrogen and in the 2nd scenario add some Cal-Mag to your solution. This should happen in the upcoming weeks. And she will definitely need some P+K boosters during the flowering stage. Hope this makes sense, keep us up-to-date and happy growing š
