Sgtosoanswered grow question 6 years ago Nutrient companies want you to use the nutrients so you have to buy more sooner. I've been using Advanced Nutrients for a while. I generally give them half of what they recommend. I round it to 4 ml/gal. Also I noticed you are using Micro which I believe is for veg/grow. The Connoisseur Part A is for bloom. Why aren't you using Connoisseur Part B?
When your plants are watered pick up the pot to get a feel for the weight. Then test it again when their dry. You'll get a feel for when it needs feeding. Generally I use 5 gallon pots and I split a gallon of water between 2 pots on each feeding. They'll usually need a feeding every 3-4 days.
Another observation: You have a few dead leaves hanging on a plant. Get rid of that stuff. It will rot and attract pests.
