Over fed or nute dificiency? Any advice?

[Aquarius 2013]

I think I over fed my auto Blueberry girls when I bumped up the nutes to 3/4 from half strength. My Snowstorm #2's are looking just fine with nothing amiss. Now after giving them just water for the last few days, The auto Blueberries are showing signs of yellow with brown spots on the tips of the lower fan leafs. Also the first node starters are turning yellow and the tips are drying up. Added water pH is 6.5 and the soil is 5.8... the sluice run off is 6.3. I'm planning on dosing them with some molasses tea on the next feeding as it seems to me that they are showing signs of dificiency. What say you? Thanks in advance for your input. Peace.

It looks like a cal-mag def but your mollassis should help that. Don't worry about those two bottom leaves that yellow,they are the first leaves and this is quite normal for some of the lower leaves to turn yellow.Just pick them off and you'll be ok.

Cal-Mag Before you upped the feed your plant could absorb it fast enough--but growing faster on richer feed it needs more.
