white leaves, any advice on what it is?

Hi,
doing an LED grow, plants are about 3-4 weeks... some were sprouted sooner than others...
I have had them on mild nutes since germination... I had a ph problem and while correcting it I watered them from above by hand... I think there may have been nute spilled over the middle of the plants.. not thinking during watering I think... I thought it could be nute burn, but once I changed the res out, the problem got worse (as far as the plants are growing white..)
I have general hydorponics 3 part nutes, and just upped them from 1/4 strength to the next level up.. general use..

I watered them from above today as I didn't want to water with the higher nutes until tomorrow, and I had some seedling strength mixed up anyway.

Does anyone have any idea what the issue could be? I do think it's from nutes being dropped from the top, but it's on all of them, so I don't think that is it. I do have a tomato plant growing in with the pot, and it's doing the same thing as well.

Any advice? or suggestions? thanks in advance..

those babies are awful small for even 1/4 nutes, personally i would be giving them straight ph'ed water until you have a few more leaves. just my opinion.

I have read it's fine to go 1/4 strength nutes from seeds, but again I guess another example of book learning vs. real world experience. I think that's likely the best idea too... how do they look though for size for their age? I have looked, and some that say 2 weeks old look friggin huge, and others that are the same age that are about the same size..
Do I give nutes based on age, or size?
Thanks

dont feed them anything but water with maby super thrive. they got all the need to get to veg inside the seed. your probly stunting the hell out of them with the fert.

Really? again, when is the right time to give nutes then? by age, or size? I was going off the feeding schedual on the bottles, but I am going to go back to water.

Is it nute burn though?

id let it have just pure water for about a week or two then hit em with the nutes half strength
Do you mean 2 weeks from now, or usually don't give them anything for 2 weeks from the start? I am assuming you mean from now

absolutely no nutes that young
Thanks for the input, again, was going off the feeding chart that came with the nutes, I guess a mistake to learn from..

i did the same thing myself too. i listened to a buddie of mine who told me 1/4 strength, fried the shit outta them lost a few
Seems to be a pretty common misconception then, as I remember it was on here I got the info to use 1/4 strength nutes in you rcok wool cubes instead of soaking in water as it would help disolve the glues faster and your nutes would be there right from the start... and seems to have been fine up till now. Flushed with cleanex and phed water.. cleaned the res and then hand watered the sites with more fresh ph'ed water and then filled up the res with still fresh clean, ph'ed water and cleaned all the lines and pump, air stones... etc that is in the res. set it back to water 3 times a day and see how it does.

One last question then,

While I was flushing, I filled my res to a mark I have to tell me how many liters are in it, but I filled to there lastnight, and ran it lastnight and then today to flush... well, the water level was lower after 2 waterings than after like 4 days of regualr running, is that a good sign?
Like the plants got all cleaned out and had a BIG drink?

Thanks just thought that was curious.
Rep points all around!
