I added my new lights this week. Couple of HGL 550's to go with my hgl 100. It's like a different world. Really impressed with them so far.
The custom nutrient is actually Fox Farms Gringo Rasta which is now called cultivation nation. I guess the name Gringo Rasta was not marketing well. My garden supply guy gave me 1 gallon each of the three part nutrient. Since it was free, I felt it necessary to use them. This week I made a water change. The first nutrient is called Lickety Split which is used throughout the grow, and added Gringo Rasta's Super Sonic Plant Tonic which is the second part at half the strength of the first. I've gotten a little gun shy. I have another plant I started before this one. A bag seed that I affectionately call Bag Lady. Unfortunately I overdid part one on her 4th week and she is now recuperating from nitrogen toxicity. Grow and learn. Then smoke a bowl... Then repeat.... Happy growing!!!!
