I have 5 plants that are 17 days into flowering. They have very pale/white lower leaves but they still seem firm and have no signs of burn. The stems have reddish stripes on them. I have been feeding with BioBloom at 4ml/L every time they get dryish. I am using coco for my medium in 3 gal buckets. I'm using a 400w HPS. My temps hover around 78-80 degrees.

I heard this could be a Mg deficiency. Might it be caused by overfeeding? According to the website, BioBloom is a complete plant food with micro-nutrients and so on. Should I try a foliar spray of epsom salts? If so, what concentration?

Today I flushed them and added 1/2 strength ferts afterwards. My ph was a little low at about 6.2 before flush.

Sorry I don't have pics. The plants look healthy except for these white leaves and red stems.

Thanks for your time.
