Ajusta tu ph y ppm puede ser más una sobrefertilizacion que bloquea la absorción de otros nutrientes. Prueba mediendo ph y ppm del agua del drenaje, si no sabes escríbeme al chat!

Hi I think your diary said your about 40cm above the canopy. If the light is on 100% power is probably getting to intense a light. A phone app called photone is a good way of checking what levels your plant likes and doesn't like. Try lifting the light or reducing the power until the app reads 20 dli if it was higher then 20 dli its from the light. Also when using LED the plants use a bit more calcium and magnesium. Hope this helps.

I think it's not related to the lamp but more with food and PH, I see you have previous grow questions related to the same, i suggest to check the PH after the food and be sure that the food you are using has the right amount of NPK
