It looks like nitrogen toxicity. Signs are usually dark- green waxy leaves pointing downward. Less nutes and more plain water until she recovers!

Possible K deficiency? What do you think?It seems like my Grape Diamonds may have a possible K deficiency. Edges of leaves are starting to fade and brown with the veins staying green. Lower leaves seems to be greener and they're showing signs of the K deficiency but not as bad. Would appreciate your thoughts, thanks!

Manchas en las hojasHola amigos! Estoy teniendo algunos problemas en las hojas y aunque creo que con Calmag se solucionarán me gustaría oir vuestras opiniones. He notado también que algunas puntas de las hojas se curvan hacia abajo, ¿cuánto creen que me está afectando la temperatura de entre 27-30º?

Leaves "praying" after lowering the lampI am in week 4th of flowering Laughing Buddha, 220W LED ~60cm from tops. Today I have lowered the lamp and the leaves started "praying", on one (higher) plant the other, mostly-indica Holy Punch seems unaffected. I am curious, is there too much light or sweet spot and it's good?
