how old are your plants? if under 4 weeks, don't use ferts. after that use but a 1/4 dose. something for vegging with a higher 1st #. when you flower, then something with a higher 2nd #. good luck.

You say that the big fan leaves are starting to yellow. Plants move from growing foliage nice and green to spending all the nutes in bud production. Often times the plant does not get enough nitrogen during veg and once introduced into flowering fans leaves start to turn yellow prematurely. Exactly when leaves should start to yellow I am not sure....but know some one on here does.
