Mr Fred congratulations for your information, but take note ,you mix yourself alot,especially timings, for instance in this video you say counting starts after sowing seeds in nursery, another video where you claim its 58 days after transplanting and maturity will be 75 days for the first fruits to set,yet in another video you claim watermelon should be out of the farm after one and a quarter months, so please arrange, edit your videos to ensure cohence and flow when posting them, in other aspects you're doing your best, fertilizer regime is variant depends on soils analysis of the particular place,so regime can't be same
