Purple Encircled

Plants are happy and healthy. Got complacent and the plants grew into a forest under the canopy... did heavy defoliation. Stretching is hopefully complete as the they're getting pretty close to the light. EC flux's between 1.0 - 1.5. When it drops below 1.0, I'll change the nutes. Has been about every four or five days lately, these plants are hungry. If the EC >= 1, I'll topup with RO water. Lately I've been adding 2.5 ML's of ArmorSI silica every second or third day. They eat through it quick and it drops the pH of the solution. The buds are starting to show and the smell is great. In late veg and a couple weeks into flower it was pure skunk. Starting yesterday it started giving off an amazing scent that smells like lemon to my wife and berries to me. Hoping I didn't defoliate too much. The plants were so inter grown the buds underneath the canopy would've been a mess and at worse moldy. Thankful, have a good week everybody.
