Week 6ix behind All week been struggling to solve the “mystery of yellow top” And “the mystery of not flowering autos” Since both coco plants are not flowering in the same manner i ruled-out the possibility of them being genetically photos instead of autos. The possibility that i’d get 2 different strains to be with such a rare deviation is atomically small. For now have developed a plan and then decided to go a little sideways. First, reducing the EC to 1.3 stable instead of trying to push the plants to the limit. This means a little less that 1/2 of the recommended dosage by the producer. Second, going heavier on cal-mag Keep mimosa fed every day as she seems to devour everything and sit in a light pot. Another thought is iron deficiency but will see in due time if reducing EC and changing watering schedule doesnt help will go and find an iron supplement. And finally, if they dont flower i will switch them to 12/12 but this is last resort, i dont beleive they are photos. Thank you all for sharing your knowledge and beating your powerful minds with me to find a solution. Special thanks to @growinggrannie Stay tuned
