Week 4 Day 1 - In the morning she looks great, very healthy looking. The boost in nutrients to the soli looks like a good move, next day or so should show some significant growth as she is now really starting to sky rocket. Later in the week when it is time for another nutrient feed, I will be on the BioBizz WK 4 sched @75%.
Week 4 Days, 2,3,4 - She is just cruising right along, reasonably sure that I have the soil and nutrients headed in the right direction. Today day 4, she had 1500mL with BB week 4 sched at 75%.
Week 4 - Days 5,6,7- Well she has gone from being a plant to being a bush. No real issues going on, watering every other day at the moment, (1500ml per with BioBizz at 75%). She has also been treated to a foliar using Alg A Mic and Fish Mix, both at 1mL/L.
So thats it thus far as she reaches the end of Week 4, see ya in Week 5 she says'
Healthy looking plants, just a few quick things from looking at your lights power output and how far away they are from the plants themselves. I would try and get the lights closer to improve the amount of PAR they are getting. Your log says 86 for daytime temp, but in the photo, the thermometer says 79 F . Cannabis plants love heat and humidity this early on. It is the bud during flower that does not like the humidity or high heat.
