Fast Buds Orange Sherbet Auto Indoor 4" x 2" Grow - Mars Hydro FC 4000

The buds are now stacking up even more. I noticed much more trichomes on all buds. I know the buds aint huge and some look and are pretty airy (picture 4), but I'm a beginner and still learning much in every grow. I fed the plants with 2ml/L of BioBizz Bio-Bloom and 1ml/L of BioBizz Calmag on day 58. I'm really not sure if the leaves of the plants are just near the end of the cycle/death or my calmag problem has gotten much worse. If I'm honest I think its a calmag deficiency.
