That just looks weird.
Beyond the weirdness, I see what may be cal-mag issues.
Did you have this problem before you added nutes?

Hazy, I have been having this problem for about 2 weeks, i just added nutes for the first time 4-5 days ago. I was begining to think it was a cal-mag deficiency. I'll try adding some cal-mag on my next watering.

Peace,

I dont think its a cal mag def. I think your burning them with too much nutes. I had the same prob with early plants from seed and most of the time they dont need much to get to growing. for ex. on my plants from seed after the first two weeks im only at 250ppm and my tap water is at 80ppm so i diddnt add much. (Before that even less) Second thing is the ph, you should have it checked because some nutes get locked out at certain ph levels. Some soils have enough nutes for a long time also i think i run hydro.

are you spraying the leaves? no need for that, especially when the lights are on. I don't care who you are water at the roots not the leaves. the only time i spray them is sometimes when i'm making clones.
 
hey man, that's almost exactly what i have, and cant figure it out...the only difference is that mine starts at lower fan leafs, and it seems that yours is also higer up...but the pattern is almost the same...first i thought ph but and then Mg deficiency cuz it was between the veins but lacking classic Mg simptoms that are visible on yours...it starts with pale spots between veins and than like it thinns and burns...nutrient burn was out of the question...till now it progressed some and those lower leafs started yellowing but i believe that is N def cuz i really fed poorly while trying to bring down ph...

Hey everybody, so it really cant be nute burn, this problem started a few weeks ago, and i just fed them nutes for the first time a few days ago. Also, I only sprayed them due to advice i got for treating deficiencies from the sick plant guide on ICmag. I sprayed them with the lights off, and put a fan on them until they were mostly dry.

Peace,

dude, check out for spidermites, i thought i didnt have them and trying to resolve this problem figured i DO HAVE THEM! and my last thought on this was it may be mite damage, cuz around some of the spots theres a concentration of mite eggs...

i would go ahead and flush them out with normal ph water no nutr. it looks like a posable lock out on your micro nutr. ph lock out is common and alot of people over look it by adding more nutrs to the mix this just causes the soil to contain more salts and become toxic the plant has to contain more salts than the soil thus it can properly suck up more nutr and water from it

sorry i rambled
