Leaves seem to be drying up, can someone tell me why?

So last night a check my girls, pH is good they look healthy everything was good. Woke up and a few leaves are discolored and drying up. I have a few plants in a dwc. Using gh flora series. I'm using cfl's but they are far enough away not to burn them. No other plant is effected (at least not yet and I'd like to keep it that way)

give her some more grow nutes . shes hungry . . she can probly take more than the others . u always get a fat kid in the class that eats more than the others

Whats you humidity?

That's one thing I'm not too sure of. Is there a meter or something I can get to check that? It's seems like it should be ok. It's only affecting certain leaves on one plant. I'm thinking maybe shitty genes? The last bunch of seeds I got didn't sprout so the vendor ended up sending replacements. Maybe I shouldn't use them anymore

Low N shows pretty bad!
DWC and GH 3 part eh....add a Ca/Mg.
I would suggest the use of a Kelp extract.....

When I added nutes this last time, I might have fucked it up. I added the micro then I added the gro, then I realized I was measuring wrong and added more micro then the bloom. I know they say you gotta put it in a certain way so you don't get nutes lock up. Could that be something? I can't get to the store for any cal mag today.

That would be it!
Water with plain water and a Ca/Mg if you got it, pHed for 7 days. Then restart nutrient feeding.......OR ,,, Leech out the soil by pouring through pHed water till half the pot size of run off goes through. Let the plant dry to need watering and restart feeding.

EVEN BETTER!

Dump and refill them !!!!! And use more nutrient! Needs more feed - low N.

Awesome, thanks so much. Is it safe to say that if I don't the other plants will get affected?

eventually they will, some are just more delicate than others.
they tell you to mix in a certain order because if you don't, some of the chemicals in the water may precipitate out of the water and fall to the bottom of the jug, and your plants can no longer access them. if you ever use a silica additive, you always have to add them first, or the silica may bond with other chems and make them precipitate if it hasn't had a moment to bond with the water

^^^ Roger got that ^^^

If in a res - you betcha!

I'll add to Rogers answer. After adding a nutrient - STIR WELL BEFORE ADDING THE NEXT PART, AND AT THE END!

Great,ill change it up and pray for the best. Hopefully by tomorrow morning I'll be able to tell something.

That's the latest that has happened

I think I had a problem before that I didn't even realize. I don't think I had been stirring well the entire time so far. Before when I would add nutes the next morning the roots would be all reddish brown and gross looking. I stirred well. Let it go over night, and them roots are beautiful this morning. This is my first grow that is actually going to go anywhere. (Other times were factors I had to eliminate) I'm new to this, I appreciate all the help. I'm sure I'll need more in the future so thanks ahead of time as well
