The bright yellow tops could be from a big temp change when you switched to flowering. What are your lights on temps and the temps when the lights are off? Does it look similar to this pic? I stole this pic off the internet.

pushit Reviewed by pushit on . White widow problem? I am 6 days into flowering and have noticed two things.. one the lower half of the plants leaf tips are curling down which i think is P so therefore not enough nutrients but at the same time every top is bright yellow almost looks like nutrient burn. To anyone that has tried growing this strain were your tops bright yellow? I have a moisture meter and only ever feed/feed/water and repeat when dry as ive read you must let them completely dry out then drench to avoid air pockets and roots Rating: 5
