Hey I have some serious yellowing of the larger bottom fan leaves, it started probably two or so weeks ago. Every fourth or fifth fan leave is yellowing and eventually dropping off I know a lot of people say that this is completely normal and that i have a nitrogen deff. but i have also read that no yellowing is normal and that i could possibly supplement the current nutes im using with maybe a grow nute or some type of nitrogen(earthworm). details: 7 weeks into flowering, using PBP bloom and liquid karma in soil under a 600w. Please helppp i dont want my babies suffereing
