2021 Spring/Summer OD Hydro Autoflowers

This week some of the plants are starting to show a few brown pistils on the calyxes as an indicator that peak bloom period is occurring. I don’t expect them to do much other than fill out a bit at this point with exception of some of the more Sativa phenotypes like the Tangerine Dream. One of the these seedplants failed to bloom properly it may lack the autoflowering genes. I don't want to risk damaging the roots in the system by culling it. I might leave it in to see what happens and transplant it before I clean out the system for the fall grow. I’m pretty satisfied with the autoflower grow so far but I do have some room for improvement: 1) Next grow I will use CNS17 Ripe possibly from start to finish to see if that improves the flowering of the plants. I feel that my feed is high in nitrates so I am starting to flush this week. 2) You can see by the plants all showed variation in physical appearance and Trichrome production. The only plant that has gone purple out of the batch and is a high yielding Gorilla Zittles from Barneys. If I grow autoflowers again in this system I want to choose plants that are a little more uniform. I think the Botanicare Turbo Garden and similar systems are best suited for clones as they grow a little more uniform. Autoflowers even from the same strain have a wide variation which is cool because every seed is a surprise. 3) I need an overhead plant support. I am not sure how the plants survived some pretty high winds. One stem broke and I repaired it enough so that the plant actually survived. 4) I'm working on a microcontroller sensor node to allow some automation to the system. My favorite plants in this batch are the Dinafem Amnesia Auto CBD based only on aesthetics at this point. The Blue Dream Auto from Humbolt is one of the smaller plants but it has quite a bit of resin on it. The smaller plants may have been stunted as my nute level from the beginning was approaching upper limits for leaf burn (1.7-1.8 EC). I had since backed down but over-fertilization in early stages is not reversible and comes at a cost of plant health and vigor. I took a video to try and show the overall garden progress. I did not defoliate this grow which makes it hard to see the individual flower structure but I will have defoliated harvest photos coming up soon!
