Brown spots on transplanted blueberry

So this is my third grow,and The first time ive had to transplant. The following are 2 blueberry plants from seed...my friend gave them to me in the same pot when they where both about 2 weeks old..this is week 4 and you can see the difference in size and they are both the same age...the one that is shorter and they only one with brown spots is the one i took out of the original pot so,the other one never actually got moved,so im assuming this has something to do with it. but either way even the healthier one has kind of rimpled leaves as you can see,are these wrinkled leaves a sign of something wrong internally? the real question is this though.why the brown spots on the smaller plant but not on the big one? my friend did feed them miracle grow before he gave them to me but they both seemed to be doing fine before the transplant,and the ones health continued,the other was droopy and still for a couple days and the small leaves began to die off,then all the sudden it perked up,started growing nicely then one set of new leaves begane to get spots and the others are nice and green and the plant continues to grow...

slight nutrient burn, dial bakc the nutes a little bit, if your not feeding right now try flushing the soil out a bit, they should be okay just tone it down some, good luck

Yup. Also, the raised edges indicate high temps. Get another fan in there or raise the lights a bit.

Welcome to the fun of growing BB. It is a finicky plant. Its a good plant to grow to see how good ur environment is. Its always the first one to start whining for better conditions.

Doc, can the raised edges be caused by low humidity? Or is it always high heat.

doc might know a bit more than me but i may be able to lend a hand, usuaully curling upward is from heat stress from the light being to close or to much radiant heat building up on the leaves (there are 2 types of temp, radiant and ambient, ambient, is the 70 degree whether you feel everyday, but if you go stand in the sun and put ur hand out for an hour, it becomes much hotter than 70, usually like 80 or up, that is radiant heat, plants can handle two different levels of ambient and radiant, they thrive in ambient temps between 73-82F and for radiant they can easily reach 95-100 degrees RADIANT heat before they will become sick, now this does not mean you can let it stay 100 degrees in ur grow room and be successful, it just means that plants can handle the sun on top of them shining down....or your light for that matter (just like with our hand before) to this temperature without becoming stressed, i hope this is understandable maybe doc canna can explain better im a bad teacher
