i grow marijuana from a clone plants seem to be healthy up until i induce them to flower and all the large fan leaves seem to turn yellow every time within the first week of flower what could be the problem.

never had a chance to reduce before leaves yellowed. i fertilized up until two days before inducing flower 12/12 cycle. within three days of inducing flower the leaves started to change

You my good sir are experiencing a magnesium def, calmag will stop the progression of yellowing leaves.

I would also keep the nitrogen up a little for the first couple of weeks in flowering
