Can anybody identify these problems for me. I'm using a bubble bucket system, ph has been roughly 6.0, hydroton as my medium. house and garden aqua flakes A&B plus roots excelurator and drip clean.

I'm really losing sleep over this worrying about my little girls

You say that you're using hydroton as your medium in a bubble bucket but the first pic looks to be growing in a plastic cup. Whole-plant pics are usually necessary for a solid diagnosis.

The Aqua Flakes are low in Phosphorus and the browning you're seeing is probably from that. The A is high in Nitrogen, the B is high in Potassium, and you'll want to find another source of Phosphorus. Fresh organic ferts that are high in P include Bone Meal and many Guanos.

Thank you, so much MF. I found another probable cause, my EC creeped up way to high, my target was 1.2 and I was at 1.6, so I'm believing it might be from nutrient burn. I changed the res and lowered the EC down to .9 if that makes the problem worse I will add Bone Meal.
