SHMEH! Can't seem to diagnose!

Hey guys, First time hydro grower here. having trouble figuring out whats wrong with her. Nutrient burn? heat stress?
Lowered the temp, raised the light and cut nutes in half after a flush. She's growing like crazy but the problems still there.
Any help would awesome.

60%indica/40%sativa hybrid clone
end of 2nd week
recirculatory hydro drip system
Clay medium
250 watt MH bulb
Avg temp/humidity 77F/45%RH
Nutrients flora series and earth juice meta-k using the directions for amounts on the 2nd week
Water PH 5.8

started on the lower leaves than moved to the top. the ones on top are a brighter yellow

I'll send some more pics if you need them but having trouble with the uploader.

Thanks!

looks like nute burn i would ease off a bit on the nutes just use half the recomended
dose fo now.what are you running you'r ppm at.?? i might be wrong so see what others think.

Thanks man i'll try that. still trying to learn this very fine art, dont have a tester so i have no idea where its at. so lets say i have one what would be an ideal ppm?

How does the new growth look? The top leave doesnt look bad.... Once a leave is burned its fixed. If youve lowered the nutes and new growth looks good I would stick with that...

its usually strain dependant,put i do recommend you get ya self a ppm meter.if you're 2weeks in veg its around the300/400 ppm mark and if ya 2 weeks in flower ya looking at 650 ppm but like i said its down to the strain so keep an eye on the new growth at the top and if ya see signs of nute burn ease off a tad on the nutes..good luck..

Looks to me like you have a serious K deficiency. Whether it's due to overdose (high ppm) or lack of i can't tell. You need a ppm meter. If you can't get one try starting with bottled water which runs about 10-20 ppm. Cal-Mag as pre directions and fert at 1/4 recommended strength by volume.

looks like nitrogen burn to me
