3 of my babies look sick...(pics)

Hello all,
Well 3 of my babies look sick. The first 3 pic are of my blueberry, it has brown spots all over the second set of its leaves. I thought the nutes were a little too much for her, she is a little behind her sisters but now i am starting to see a couple on the other leaf. The others are bubblicious and skunk (they look the same, i may have mixed them up cause bubblicious looks nothing like her siblings.) They are growing great but the leaves are "rolled" on the sides, is that something to worry about?

Blueberry notoriously loves low nutrients and it is common for the plants to have curled leaves; however, the brown spots are definitely not normal and/or good. Fill out the troubleshooting form at the top of the forum to give us some insight.

I'm sorry, i am a n00b, but i dont see any troubleshooting form??

Can anyone give me an idea of whats going on??? Please...

well to start, you need to knock down those temps. Your digital thermometer says that its 89 and that is a little too warm. How close are your lights to the plant? What type of light are you using? What is the strength of the nutes you are using? What is the pH of the water you are using? What nutes are you using? What is your medium Hydroton or hydromite, or something else? What are your daytime and night time temps?

The troubleshooting guide is at the top of the basic growing forum, or the plant problem forum. Please answer the questions above so that we can give you better advice, but first get those temps down somewhere between 70-80 degrees.

Potassium deficiency or lock out.
Foliar feed with a micronute supplement if yo uhave it, or a COMPLETE grow fert with a high LAST number, just to keep the problem from worsening.
Check your pH. Adjust if necessary. Give your bully a pet for me!
Rolled leaves on the sides, could be under a hot spot- typically that's a sign of acute heat stress.

foil causes hot spots if that's what you are using
