coloración peculiar en hojas superiores

Hi there, Your plant is so much green in colour and you are using pretty decent amont of nutrient.I assume It may lockout rather than deficiency due to improper pH or abundant of other nutrient in that pH.Find out the base cause. As long as you are giving the perfect growing conditions and feeding, they will not go worse.Before you do anything, make sure your water pH, ppm(EC) and run off are in corrected range.If you are growing in soil, keep your pH around 6.0~6.5 for both of your water and run off.Also in soil,the less nutrient the better to prevent lockout. Keep your temp and RH in proper range which I prefer around 25C and 50% for all stages.Slightly different between day and night. Happy Growing... ✌️

Way too much nitrogen in the plant. When leaves get dark green, shiney, and leathery. You are about to go into nitrogen toxicity. Nitrogen also hinders bud development in flowering. I would check your run off ph. I imagine it is off with heavy nutrition in play. Looks like potassium deficiency. Ph can lock out nutrition. So my bet is on ph. In flowering your npk ratio should be 1-2-3.
