Somethings Wrong!!!!!!

75 plants
super silver haze
soil
4 weeks flower

about 10 of the plants are getting yellower and yellower. starting with the fan leaves and then yellowing all over. i have been feeding them and the going two waters between feedings. im waiting for them to dry out inbetween waterings. do you think is a lockout or burning? i am going to try and get pics up. it seems really bad but only on a small percentage of the plants. on the really bad ones almost all of the fan leaves are yellow and falling off. please help

Hard to say with no pictures but I would try flushing those and see if it helps. Wish I could be of more help. I am sure you have checked but your PH, temperature, moisture all good?

Give them some extra nitrogen often at this point of flowering they need more nitrogen..

pictures would help a bunch, but yellowing of the leaves (starting with fan leaves) is completely normal when plants get into flowering. they are drawing nitrogen out of the leaves to stack up on buds. just give your plants more nitrogen.
