Buds are looking very healthy now, seems to be tottering along nicely.
Had some lower leaves showing magnesium(?) deficiency, then dropping off and dying, but that's apparently normal for big plants into flowering
Hey there looking good, if it is a magnesium def then it will most likely mean the root ph is a bit low locking it out as if your using tap water its likely present . Sure it’s not nitrogen ? You can tell by how it’s yellowing which one
Best of luck
