3 of my babies aren't looking so good...(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?

Anyone?? Please help..

cool set up i would love to learn how you did it

mine rolled a little like that when they were younger, nothing to really worry about to much they will straighten out.

my hypothesis is that the rolling is either overwatering or heat related. either cause they have to much water in them and for some reason the leaves curl, or they are rolling to get away from heat. but i never had problems with either but thats the only conclusion i could come to.

what's your Ph? the spotting could be caused by wildly fluctuating Ph

i got that same spotting everytime i transplanted and didnt use the same type soil

Thanks, we built it out of sheet wood and 4x4's (got some pics for ya). My ph was out of control last weedend also i added nutes. Since i changed the water last week it has stayed between 5.5 & 5.75. The Blueberry is a little behind the other plants, could this be nute burn?? Yes my heat is high, i live in a HOT/DRY state, but we are cooling down big time so i hope that will help i also raised the lights, is it too much??

I'm thinking the leaves are curling to get out of the "sun". I think you have the lights too close and it's probably way too hot in there. They will do better in the 40's than the 90's. The brown spots are probably nute burn; they can take too little better than too much - especially at this tender age. Think of them as babies; you wouldn't give a baby a delmonico steak would you?

Lol, no i would'nt i will keep that in mind, none of the other burned though, so i will need to find an in between. My temps are in the mid 80's now (going lower as the days pass, soon i can add more light). Thank for all the help...

I did that with mine....I tried to make it perfect with nutes and overwatering and what have you and they started to get ill, now i water once every two days and leave them to and they are happier than ever....

What nutes are you using, and how much?
