As of the afternoon of May 15th, I have begun some LST with binder clips/safety pins and some soft pipe cleaners. With the exception of the Critical Jack, I think most of the plants are showing some signs of excess Calcium and Nitrogen so I am going to take CALiMAGic out of their feeding regimen and cut the nutrients down to 1/4 strength as of this afternoon. The Dinafem Critical Jack Auto is now the tallest plant and seems to be the healthiest one of the bunch at this point, she keeps amazing me every day. The Seedsman White Widow Auto is not very tolerant to feedings and its stems & branches seem to be weaker than the others; very bushy. Both the Dinafem Industrial Plant Autoflowering CBD and the Mephisto Ripley's OG are very healthy but are growing very squat and bushy -- which made trying some LST for the first time a bit more challenging! As of the evening of May 17th, I noticed pre-flowers on both the Critical Jack and the Ripley's OG. The Critical Jack is certainly stretching out right now! The White Widow and the Industrial Plant CBD look like they should be getting pre-flowers by the end of the week. The Critical Jack has taken to being under the ViparSpectra 600 light more than the MarsHydro Mars II 1200 light -- something to keep an eye on?
