So problems I see. You have a nutrition inbalance for stage of growth. In vegging your npk ratio is 3-1-2 in flowering it shifts to npk 1-2-3. Plants need some rest daily. 4 hours at least to cool off. You were running too much nutrition in vegging the glossy dark green on leaves is the indicator for that. Then my last tip for better leaves is control and maintaining your soil or substrate ph via run off.

Your plant is stressed, unhealthy and exhausted from being grown at 24 hours of continuous lighting. Plants need sleep, just like every living thing on planet Earth. A plant can not function properly without sleep. A plant needs sleep for a normal functioning metabolism and a healthy circadian rhythm. A plant needs sleep to undertake a correctly functioning photosynthetic cycle. A plant needs sleep to undertake certain metabolic processes that it can not do when the lights are on. Without being able to do these metabolic processes, your plant will become sick and dysfunctional due to an imbalanced metabolism. Change your light cycle to 18/6 and with some care and some luck, your plant may recover well enough to flower normally. Keeping the lights at 24/0 will ruin your plants health and lead to failure during flowering, that is if it survives ling enough to do so. Nothing on Planet Earth has evolved/is designed to live for days/weeks/months without sleep. Your plant will grow just as fast and just as big at 18/6, as this light/dark routine is optimum and the healthiest and most effective schedule for cannabis, auto flowers or photoperiod plants in vegetative growth. If you are interested, google "photosynthesis" and this will further explain why plants need sleep to be able to function correctly. Hope this helps, Organoman.

it has a certain yellowing in the upper leaves, I have already changed in this fifth watering with fertilizers to neutral pH bottled water.
