Start of a deficiency or bleaching?

Don't think it's bleaching because I have 3 other plants and nothing on them. They are in FFOF,I'm not excatly how old they are because i got them from somebody else

It looks like a tiny bit of nute burn what are you feeding and how often and are they all the same strain?

Haven't feed them anything yet only ph'd water

What kind of lights are you using? And how close are they? I see the soft ties there, doing some lst? My guess is that they got too close to the light.

600w MH at 24 in. I have 2 other plants same size with no signs of bleaching.

If it was nutrient burn it would be all over. My guess would be that maybe some water splashed on the leaf right there and burned it a bit. When you water always be sure not to leave any of the leafs wet under the light, the water acts like a magnifying glass. I always raise my lights way way way up, water, then direct airflow over them to dry the leafs, and once they're dry drop the light back on them.

My advice is to keep an eye on it, if the problem starts showing up on other leafs or progressing at all you've got a problem. Throughout the grow leafs get damaged. It's good to be proactive about real issues, but when you get the hang of it, more often than not, leaf damage is environmental.

Only affects big fans starting near/at bottom?

What else is added in the soil and pH of water you have been dropping.

"there is NO leaf burn evident in your pictures.
foxfarm soil will not feed properly for very long.
pick up some organic fertilizer and follow directions immediately to avoid issues.
water when container is dry and light, 1/4 of the container volume in water should be added all at once when you do."

I think I've narrowed it down to the water. I was using distilled water and apparently the buffer capability is weird. It showed up on new leaves right after watering, and is even on one of my plants I did from seeds 20 days old a little bit on 1 tip. It was ph'd at 6.2 and is on the top leaves which is weird.

Actually not sure what it is to be honest it looks like some sort of burn to me. Going to try the new water with a small feeding. I had one seedling I did from seed that is 20 days and is showing the same thing on it's tips but not nearly as bad, it shouldn't be a deficiency with this one yet because it is in ffof. It's just weird to me because it's on all the upper leaves.

That's why, especially with organics, I like to wait till I see a nitrogen deficiency starting before I feed. Nitrogen deficiency is the most common and the easiest to spot, as soon as the bottom leafs start to fade look at the veins, if they're all still green it's Mg, if they're sort of blotchy but for the most part fading all over it's nitrogen. Typically you'll see the nitrogen def first though. Good organic soil should only require the addition of the macro nutrients, and maybe Ca and Mg. But 90% of your watering in organic soil should just be straight water, pH adjusted if it's tap.
