Looks like you have or had a calcium deficiency. When you grow under led lights the plants need more calcium. Best of luck the rest of the way.

Leaf tips are browning Ciao tutti, What is going on with these leaf tips? It’s the third day of their Flush & It can’t be NutBurn, or the color of tips doesnt look like NutDef! Is the light stress? If this de-coloring continues, will it effect the buds & final yield? Thanks

Yellow/burned tips & curled leaves I have an issue with some yellow/burned tips and curled leaves. I already suspect that mainly is from light stress but could also be a nutrient deficiency? I´ve raised the lights the max I can and keep it at 80% for 20 hours. Biobizz soil and nutrients. Thanks in advance!
