Roots are not developing , leaves collםr is wrong and very small flowers

Cannabis has hugely different nutrient requirements to what a farmer would be using to grow broad acre crops. Way, way different. Get some dedicated cannabis specific nutrients and I am positive your plants will be a lot happier and healthier. Strange leaf shapes are of no concern, but the rest of your issues are being caused, no doubt, by using inappropriate nutrients for your cannabis plants. There are many, many cannabis specific nutrients out there, made by companies like BAC, GHE and Bio Canna, being three of the simplest to use and all will produce excellent results, with very happy and healthy plants in my experience. Hope this helps ,....... Organoman.
