UK Outdoor Auto First Grow

Weather not so great again this week but plants well into flowering, leaves on the Northern Lights and Super Silver Haze have started to go darker which leads me to believe that these strains will be ready to harvest first, maybe in 3 weeks time. Will start easing off on the Guano tea as some nutrient burn on a couple of leaves, though not too much to worry about. Smell is increasing but manageable, Noticed some curling of the leaves on the Super Silver Haze, restricted watering but problem got worse, have increased watering for this plant and it is recovering nicely. Have also started to trim lower leaves which were yellowing due to lack of light getting to them. With the LST and bending which I have done I have about 10 large collar/tops and another 15 smaller ones. Due to how big the plants have gotten it is becoming more difficult to take good pictures, but I shouldn't complain about the size. Think i'm doing ok but happy to have some suggestions.
