Why are my plants looking like this?

My Veg closest has a problem. The only thing I can think of is I used out of date grow big or/and the air in the closest isn't right. I don't think I have enough good air exchange and it's a little
warm at times, but not over 90 degrees. They are on 18/6 light schedule with a 250 w compact flourescent. I don't check ph, but I have ordered ph strips to check soil and water. The fans are not blowing directly on or at them either. This just started happening recently and although these are clones from an old mother plant(almost 2 years old now), some of my newer clones did the same thing. Is there any way to correct this? Thanks for any and all help.

looks like it could be micro nute deficiancy to me... like zinc and iron.

Whats is your temp and humidity?

dam that sux dude.. what nutes/soil/water u feedin?

id say the mom u took the clones from is weak, or ur lighting isnt strong enough, what kinda lights do you have on them?? mine grew the one bladed leaves when my timer screwed up and didnt light them at the proper veg lighting schedule. might also be a deficienty like the other guy said but before dumping extra nutersw id make sure the lights are close enough and on the right schedule!!

Those are Foooked up!

I am leaning towards a micro nute deficiency. The grow big by fox farms I used has been open since late 2010. I usually use the whole line of fox farms liquids and the cha-ching, beastie blooms and open sesame. I also experimented with jacks classics, but since have gone back to fox farm. I use bacto soil and a pro bx soil. The bacto has micro nutes in it and I am wondering if they have reacted with the fox farms and caused a ph problem? The lights I use are cfl 250 w is the biggest. The plants love them, so I don't think it's my lights or distance from. Temp runs a little warm 89-91 degrees. Haven't had a problem having enough fans to exhaust. If it is a nutrient deficiency, what is the best way to correct it? thanks again for the help.

it looks like mag deficient*yellowing on outsides of leaves try adding some epsom salt. however the crumbled up leaf looks like something else.

I would try to bring temps down as much as possible. Also find out what your humidity is.

Yikes. Thats not looking very good. Burnt new growth is never a good thing. How long has it been since the tops have shown significant growth? Like a few inches taller?

Dude....... i looked at the picks again and decided those plants look in really poor shape.... I think you just need to start over and save your self the restless nights and Frustration. and put them down quit causing them pain...

I don't have restless nights over this, it isn't the end of the world to me. It is a learning opportunity and that's what I am doing with you guys help. I probably will put them down, but not after I try a couple things first. I have other clones just don't want the same fate to fall upon them. Thanks again ya'll!

Those are over fertilized. Burned, etc... Adding supplements or ferts in general when the plants are not asking for anything will get you every time. Any deficiency that you are seeing now is caused by an over-abundance of P or K that has locked out the absorption of one or more of the needed macros and micros. Overfeeding plants under a fluro is really bad and hard to recover from. Adding more feed at this point is not going to help.

Those tops are done but if you flush em out the lowers will probably be ok and you can top them and move on.

Good luck man.

I flushed and they still don't look good, so I am going to end them as I have more plants that are healthy and I am outta time for these. Thanks again for all the good advice. I learn new stuff everyday and a good way to learn is by making mistakes unfortunately.

That looks like an Mg def. MJ seems to crave MG, many strains, especially in early flowering.

UPDATE: Figured out what the problem is. Tap water is high ph 8 or 9 from what I can tell with my ph strips. Of course the plants are showing signs of a micronute deficiency because the ph is so high the nutes are locked out and not being used. To add any deficient nutes would just burn or be useless until ph is corrected. I have ordered a digital ph meter and some ph up and down. Until then I have added coffee grounds to bring ph down to 7 or 6. I have pepper plants and tomato plants that are being affected by the high ph as well. Dam it all to hell!

They were fine up until something changed. You had good growth going on and then something changed and you developed issues.

PH issues in soil are exceedingly rare. Sorry man but I think you analysis is wrong. You had some severe nutrition issues and classic claw leaves that are a tell-tale sign of burn. Just an experienced old stones 2 cents...

Yep I am incorrect doogleef. I really have no idea whats going on with the veg closet. I am getting claw leaves from all my plants. Could my 250w cfl be messing them up or am I just burning them with my nutes? I am thinking I didn't feed them correctly then overfed and burned em. The thing is now these other two new plants given to me pre grown are showing signs of burn and clawing. I only fed them with ff grow big at 2 tsps per gallon two feedings in a row. I am growing in pro mix bx with mycorrhizae, while these two new plants are in some ff ocean forest mix. How do I get these plants back to health? Is it worth it or should I just start over?
