Please help my babies are burning!!!

I have plants about 1 1/2 weeks old...They are all growing very fast but I have a problem.
When I was sprouting the seeds, someone told me to put nuts in the water (a very low dose) so I did...One of the sprouts came out with a yellow round leaf and I realized that wasnt normal...
Also I was making the mistake of checking the PH in the water before the nutrients, so I fed them about twice with very low PH...
They are all growing on 5 gallon soil pots, with a 1000watt light, I have a blower so they are not hot by any means...

The biggest problem that I'm having now is that some of the first leafs are now kinda burned and with yellow spots, can anybody tell me how to fix this problem and do you guys think my plants will make it??
BTW I'm using floranova grow, do u guys think the floranova grow and bloom is good??

Could be the soil.u should get a soil tester to a sure the soil is not to strong

I am using foxfarm Ocean forest...I have heard its really good...

One of the best soils you can use.. Not sure about that nute tho?
As for now, just give them straight up water... Those leaves may never make a 100% recovery, but the rest of your new growth will be better off!

U never heard of those nutes?? I got them from a local Hydro store, the dude said it was really good....

I haven't.. But hell, what do I know!?
If you got them from the local Hydro store, I'm sure they're fine. What matters most is what the #s are & how much you give them... & there's no REAL best # set to pick either, I was adviced 20-20-20 from all of my research, that nearly killed my plants. Som like 15-17-15.. or 8-5-8.. Currently I'm using 10-15-10..
It really all depends on the plants!
Either way, right now, just back off all nutes!!!
& Definitely get a pH tester & test your soil.. & test it again a few days after stopping all nutes. You need to get the best SOIL pH level you can get & go from there!

I have a PH tester for the water...Is there a diff. one for the soil??
even if the leaves at the bottom that are burned dont make it, would it affect the rest of the plant?? I mean do they look healthy to u??

As far as I can see in the pic it just looks like a bunch of nute burn.. It's nothing too horrible! They're pretty young yet & there will be LOTS of new growth that should turn out fine. Just watch yourself with those nutes!!
Maybe try to do a little more research online about pH levels, nutes, etc. Hard to get a perfectly clear answer, as all plants are different. But it will help you get a little better of an idea!

When the bottom (feeder) leaves start to turn yellow and wilt it means the plant is lacking nitrogen. She is thursty start feeding her some nutes with a high N content

But do they look in good shape to you??

they look healthy to me, it's not nute burn but quite the opposite. Give them some high N nutes they will thank you for it

NO NO. Dont give any more nutes as you WILL defo KILL your little plants . You say your plants are only 1 and half weeks old . Wellwhen you planted your seeds that seed has food stored in it for the porpose of feeding itself once planted and that fox farm soil will have nutes in it for at least 4-5 weeks .Lay off the nutes for 3-4 weeks and see how they go , all newbies want there plants massive and want them to grow massive so what they think is that if i feed the plants loads of nitrogen they will rocket up . Yes they will shoot up but then you will start to get problems and then you try to fix the problem but your actually causing more problems .Fix this one by just giving water for a few weeks . I dont feed my plants any nutes for 6 weeks and then i start off on 1/4 strenth and work my way up to full strenth . Sorry Majek i have to dissagree with you , If he gives plants feed with high nitrogen he is sure to make matters worse .
Your plants have all the nitrogen they need for the time being as plants with not enough nitrogen still look and feel healthy and takes longer to brown up and crisp up .
Plants with too much nitrogen the leaf tips start to burn and then burns the edges of the leafs the all the leaf .
This is the tell tale signs of what your plants are showing ,
Can you get any clearer pics away from your hps light
