Great growth and health. Small problem narrowing down little issue

So i got these girls under a 600w metal halide. Started from seed. They are in aurora green lite soil. Using Biobizz for nutrients. Right now they are on there 25th day of veg under 20/4 for a light schedule. Up to this point i have had no problems at all. They have been very healthy. Showed preflowers at 3 weeks. I fed 3 days ago with bioheaven and biogrow (not my first feed). The following day i noticed the newest growth on shoots scattered through the plant looked somewhat burnt. I am surprised because it is mostly just on this one plant but i notice a couple leaves throught the room that had those faded spots in the leaves. Not just along the edges. So my question is does this look like a nutrient burn to you folks or do i have some sort of deficiency happening. The yellow edges seemed burned to me but the faded leaves i am thinking is something else. I am dedicating alot of time and money into this as i am looking to get into this feild on a professional level. I have 10 or so grows under my belt but still have alot to learn and am happy to hear criticism. Just looking to get some help and do this right. These are all females and will be supplying clones in the near future.

Please leave your thoughts and give me your input. I am hoping to resolve the issue as soon as i can with the help of this site.

Thanks in advance

this looks more like either physical damage, like being brushed, eaten by bugs, or some kind of genetic issue. your plants are a nice medium green color, or so it appears in some of the pics. if you don't have bugs, then I'd wait a while and see if it gets worse. there might be something wrong genetically with the leaves which you can't fix. be careful about how much fertilizer you add.

thank you for replying. that is interesting. So you think picture one is not nute burn nor is the others? before now i hadn't seen any signs of this happening. i do not believe it is physical damage because it happened overnight basically. i have not noticed any bugs but thats possible. This is my first grow at my new place and i did a pretty good clean before but ill have to double check.i figured it was something with nutrients lack of/or excessive amounts because it affected all of the newest growth on all the branches. there is only that one plant that has the burned look like in picture one. there are two that have that faded color in picture four. i watered this morning with plain water no nutrients because i wasn't sure if it was nutrient burn. would you recommend that i go ahead and feed them next time?

it's so subtle and early right now, it's hard to say if it's nutrient related. I see the pale color of one leaf tip but don't know the cause. it's easy to go heavy on added ferts so I'd say cool it for a while on the ferts and see what happens. maybe they'll be just fine. just because you see some yellowing doesn't necessarily mean if fert burn. it could be due to any one of a number of things. when in doubt, go easy on ferts.

Plants look fine to me. In one pic you can see the very tip of the leaf starting to burn which is good. You found the plants limit cut back a little on your nutes. The pale leaves look perfectly fine for new growth. Don't drive yourself nuts chasing shit that isn't there.

I blew up a leaf from your last picture. You might be seeing the start of Mg def. Otherwise I agree with what the others have stated, they look pretty good.

Thanks for the help all. Much appreciated.
Just wanted to clarify that the pale faded color I was referring to is not of the whole leaves. It is the part of the leaf that orbo put a square around in his reply Wasn't sure if that is just something minor or the start of a deficiency. Sorry for the confusion

This is my first all organic grow. Do you guys recommend going with a light feed with every watering or feeding every other watering?

Pollishpollack and krypto- I'm going to be watering tonight I believe. Going to see how they look today after work and decide to water or just a very light feed.

Orbo- yeah that is exactly what I was referring to by the pale fade. I know the pale color on shoots is just from quick growth but what you pointed out is what I was questioning. Your thinking this is a lack of calmag?

Much appreciated

you need to discover what's in the biobizz. if it has calcium and magnesium in it already, then it might not be much of an issue. if you decide to add more go easy on it. right not that really doesn't look like mg def, but it could be the earliest stage. usually we see a golden yellow spotting as mag def and that's not quite what you have there.

Totally agree with @polishpollack , no cause for alarm just yet. Your plants are just now getting to the point of needing real attention. You haven't mentioned, whats the water source?

So after looking them over today and checking the spots of concern it appears there has been no further damage. they were thirsty for some water today so instead of jumping right back into a feed I gave them straight water once more. See how that turns out.

I am using local tap water that I let sit out for atleast 24 hours prior to using

ReAlly needing some second opinions. All of a sudden today I notice that the pistils on 2 plants are red and that the plants appear to be flowering. So many pistols all clustered all of a sudden. These were the first plants to show preflowers. I'm very thrown off because I am running my lights 20 hours on 4 off. Can anybody explain this? The other three plants are doing well. Could there be any other reason pistols going red other then pollen because I don't think that is the case. Any help would be great Ive never came across this
Thanks again
