Couple questions..

[John Doe]

Im using a 400W HPS I foilar fed about 3 times a few times with just water and once or twice with some either foxfarm grow big or big bloom. Sigh... I cant even remember.. I also dont remember if it was tap or my R/O water

Also I didnt start these plants myself they were all given to me.. but it doesnt make sense that it would burn one and not the rest ya know?
Is it possible it could be from his soil? But then again I dont think they were like this when i 1st got them. also the majority of the plant has 3 leaves except for the new growth..

once that scab has formed they won't grow back together. you need to tape em up as soon as they break while the wounds are fresh. i suggest splinting the sickly half to relieve some of the strain of supporting itself, which i urge you to do anyway once you begin flowering.

Hm, it might be the soil, then.

Some of the first pictures you posted with the plant's fan leaves curling inward and down told me it could be over watering, maybe even improper soil aeration. The soil has to be nearly bone dry before watering again -- Mojave desert, cremated man's ashes dry.

The plant has to be just on the verge of getting to wilting, but not so much that the turgor pressure is causing the plant to noticeably go limp.

What kind of mix do you have? You said something about having a clone in Fox Farms soil. Are you using that, and if you are did it include perlite, or did you add any?

Another likely possibility is the soil has got too much food in it. Do you have a TDS meter, maybe something that measures the water hardness?

Yes it had perlite and I added some aswell. I dont have a water meter and I will put a splint on her tomorrow thats a good idea thanks.
