First Time Grower, Longer Term Toker

This week we have implemented the topping technique to stimulate growth outwards more. Snipped just above the 3rd node on Plants 1-3. Plant 2 is doing amazing, really spreading out and the roots have grown super long. Plants 1 and 3 are doing great too, not as much growth as 2, but they're very healthy. I did manage to save plant 4! Covering all the pebbles did wonders for the plants health as well as keeping the water at a decent temp. No topping was done to plant 4, but She's doing beautifully. Had a little bit of a scare, it was doing awful with yellowing leaves and stunted growth. Its a real survivor. For this week's nutrients levels I repeated last weeks nutrient levels for Plant 4 for since it's roots aren't as long as it should be and it's only half the size of the other plants. I don't want to chance having nutrient burn in any form. For the other three plants, Nutrients calibrated for 4 gallons of water: Flora Micro (2tsp), Flora Gro (2tsp), Flora Bloom (1tsp). Water pH: 5.6-5.7
