help!! Is this from low moisture? Pics

[uwazayn]

Soil grown, 3rd wk, I use 4 cfls w/6000 spectrum, temp is approx 78, but moisture level is only 20percent or so.. Nitrogen level in soil is good but my leaf tips surprised me looking burned..
Any opinions or advice would be awesome & greatly appreciated...
Thanks

Did the discoloration start on the new growth or the older leaves??

Looks like nitrogen burn to me even though
you said the level is good in the soil imo.

Just the new ones

Flush it bro....And I don't mean down the toilet..What are you running for nutes? What kinda medium are you using? That does look like burn but why are your bottom leaves yellowing at the same time....Lack of mag in the mix?

Thanks, i have that pic also, but by the looks of this pic, its telling me zinc problems. Which im not familiar with

 

[Mr.Moniker]

You need to flush then. There's no way you should be having zinc problems (which is a micro nutrient) unless you have nute lockout.

Milovan nailed it

You could be deficient in more than one element/nutrient. A deficiency or excess in one can often inhibit a plants ability to uptake another, this is what's meant by 'lock-out'.

If you give us some idea of what feed you've been giving them, we'll be able to give you a better guess as to what is causing your plant issues. My guess at this point is N deficiency also deficiency of macro's.
