Slow and steady is the m.o. for this plant. There's been a level of reliability to this plant that I love. No issues watering or with the light. It's directing in front of an intake fan, which hasn't caused any issues. I've begun my feedings with nutrients. I use Emerald Harvest product line since I've had great results in the past and they are really easy to use.
My plan is to water with nutrients up to 2 -3 times a week. The roots probably haven't hit the reservoir yet, so there is no need to water a couple of times a week and until I really see the demand it's probably going to stay at twice a week for a little while. When I feed I like to keep my water at room temperature and PH 6.0. I find that keeping everything consistent will only help your grow. I water from the inside (closest to base of plant) to the outside. I try not to disturb the soil too much. I have 12" drip trays which are pretty good at holding the run-off. I am still using purified water that is store bought. I buy in 1 gallon jugs so I just need 4 a week, which is about $4 per week right now.
The lighting has been increased to 10K lumens, which will only increase as the plant grows up towards the light. I'm glad I switched from a 3000k quantum board to a 4000k quantum board because the growth has been good. I'm excited to see what happens when the roots finally hit the reservoir and the explosive growth starts to hit.
