New shoots dying

Does anyone have any idea why only my new baby shoots underneath my fan leaves would be dying off, looks like they are turning dark brown and shriveling,

using bubbleponics, ph 6.2, feed at half strength, distilled water only(changed every 7 days) and clean resevior weekly, also foliar feed daily with advanced nutrients VHO, 2 105 watt cfl @ 6900 lume ea., temp 68-78, humidity 45-69%, water temp 69-74, as a whole my entire plant looks healthy except for the new baby shoots that are starting to develop, I am 2.5 wks into veg, and lsting, is this a calcium defficiency, or maybe underfeeding,

Sorry no pics will update soon.

If you are talking about the little round leaves, they should srivel up and fall off. Those are for only the first stages of growth.

Im talking about the new development on the stem, where new nodes/fan leaves will grow, when those are mini leaves they alone are starting to discolor and dry. not the rest of my plant.

Sorry to hear that. Nothing I can help with then. Good luck
