Why the canoe effect on Fan leaf

1Right_Angle
1Right_Anglestarted grow question 3 years ago
Can anybody help me ID what is happening to these Fan leaves, at the top of my Black Willie. Leaf temp is 1c cooler than the room. Leaf 22c, room 23c, rh%55, lite distance 45cm. The leaf is showing that its folding like a canoe. Always thought that was signs of “ “too hot”.

Leaves too close to lights. May need to raise lights or dim wattage just a little

I think you are overfeeding them with an EC of 2.95 This maybe lockout or nutrient burn. They look the same in the beginning. Good Luck!

A simple vista se ven bien! Las hojas en forma de canoa pueden ser por demasiado calor, que las luces estén muy cerca ó que sean muy potentes, pero el calor no es tu problema si estás en los 23c y la potencia de la luz y cercanía tampoco parece. Mientras estoy escribiendo esto entre a tu diario y observé que hiciste LST, no soy experto pero siempre que hice LST mis hojas se deformaban ligeramente. En cuanto a las hojas de arriba, no me preocuparía por esa ligera deformación, se ven bien, quizas algún ventilador soplando muy cerca pero nada de que preocuparse. Lo que si me puede llegar a preocupar son esos puntos blancos en las hojas, no logro identificar si es resina, polvo o acaros/trips, ojalá sea lo primero pero sin duda miraría eso antes que otra cosa. La planta se ve genial despues de eso
