Green Crack and Orange Sherbet (Autos)

09 JAN: Soil still slightly moist under the surface, so no watering today, but tomorrow, i do believe, a watering will be in order. I feel like I am having some difficulty getting the nutes just right. Think I may need to pick up some things before the next grow, like a source of potash so I can increase K levels independently of the Fox Farm 3. I wasn't sure in my last grow, but it would seem the Fox Farm 3 isn't providing the ratio of NPK I need for mid-late flowering. Guess I could just be reading the plants wrong, but I'm less confident that this is true. When my last grow experienced similar deficiency signs, i blamed it on my inability to control soil pH and thereby drastically affecting nute uptake, however, now I have great control over the pH of the the overall system and I still see signs of K deficiency. On the subject of mistakes I've made this grow, I think I made a pretty big mistake not putting the Orange Sherbet in 5gal pots instead of the 3gal pot. On another note, some may see one of the Orange Sherbet have yet to start filling out, and I do not know what to do but to let her just do her thing. I do believe both the pot size and the nutes are playing a big factor in this; I did really good LST training early, so she filled out amazingly, but now I think it has spread her too thin for the pot size. IDK, maybe I'm just imagining it. 10 JAN: Watering today. 2L each taken from 2gals pH'd to 6.5 12 JAN: Feeding today. 2L each taken from 2gals pH'd to 6.4
