New leaves coming out "wrinkled" and small.

I have 2 plants doing well in a pro-mix soil in a small cab under a 70w HPS. Both are bagseed. One is tall and stretchy, the other is short with very short internoidal spaces.
The tall one is training horizontally pretty well and was going superb, but it started to grow new leaves on the upcoming side shoots that are weird and wrinkly. At first I thought they would "smooth out", but they haven't. They are small, wrinkly and look like little stars. The leaves are ulso curled up from the bottom in such a way as to make them look "toothy".
I have no problems on other plant and did only the mildest of fertilizing once (very diluted).
I do not know how to post pics as I am a stupid and old noob, but I really would appreciate some help from you "kind" experts!
Please be gently, it is my first time. Oh, yeah. I also have fungus mites. Could it be related?

Fungus mites or gnats?
If you have gnats, you have standing water or a swampy condition somewhere.
Do your pots have built-in drip trays? If so, that could be contributing to ALL your problems.
Excessively wet soil conditions breed bugs.
They also make the plant act in funny ways, like sho deficiency symptoms even in the presence of adequate food, because the roots can't uptake it without enough oxygen present.
Did you add perlite to the promix? Is it promix regular or 'BX'?
pH could also be a culprit, especially in a peat-based medium. And the combination of low pH and high sogginess will bring out the WORST in your plants.
You will also want to start feeding. If the plants have more than 5 sets of leaves, they are overdue for it.

Come to think of it, I got the pro-mix ("pro formula?". Is that normal?) AFTER I potted those. They are in a weird organic potting soil mix that has a little too much organic matter for my liking (wood chippish stuff) and I remember reading that the mite babies feed on organic matter in the soil. Hmm...

So should I repot? I bought a better container to fit my small 15" x 15" growing space. Are you suggesting I mix the Pro-Mix with some perlite (50/50?)? Do you think it is ok do to it? It's now or never in terms of the screen, cause I am touching it but not tangled yet.

I am not using pots with built in lips, and I think the gnats just came in when I stupidly first brought soil into the environment and never sterilized well.

Anyway, about the leaves. What does it sound like to you? They look like spindly little wrinkled starfish. Almost like they are fried-ish. dangled a small computer fan in there yesterday to blow across the leaves -in addition the the one I already have in the cabinet (which was mounted too low and so isn't really blowing ACROSS the leaves.)

Well, this is a learning experience for me. These are bagweed and I have 4 Bubblegum babies vegging under some cfl's that I will probably make into my mommies I guess (?).

Lots of fun this first time thing... Thanks for the help, StinkyAttic. :rastasmoke:

You can repot in flower. The plants want a gallon of dirt for each foot of main stem.

Wood chips aren't good.

A pH meter or liquid indicator is important if you aren't certain of your soil pH, and you will need it eventually anyway to help troubleshoot any deficiency/tox symptoms you see.

If you have an agway near you, get the composted cow manure with humus, mix in 40% perlite, repot into that, and watch your plants look better in DAYS- seriously, it's rich organic goodness and pH buffered at 6.8-6.9. I use it personally throughout my grow and have NO problems with pH EVER.

Bugs, treat tthem with pyrethrin. Do it NOW becuase once you get bud-set, you're VERY limited in what you can do about pests.

Oh- and you need to fertilize!!!!

Sounds like either pH problem or thrips.

What are thrips?

Shitty little bugs whose life cycle includes a stage in the soil and a larva that lives on the leaves and eats them, especially the lowest leaves. A bad infestation can cause some real damage.

Thanks for the help. I will repot in better soil, feed those babies some fertilizer, etc.

I broke up some BT donuts (tiny, tiny, crumb) in some water and fed it. Maybe that will help too.

Beneficials FTW!

Please pray to the Ganja God for me. I repotted the 2 plants from the crappy thing I was using into a larger (but taller) container. One of the plants is short and bushy and very healthy looking, the other is a tall stretchy plant that I was training horizontally-ish. The tall one developed the wrinkly leaves on the new side branches I was trying to grow to the same height SCROG-style.
When I was replanting, I noticed that the pot hadn't drained well and it felt like the whole thing was one thick overly wet heavy clod of roots. Gnats or Thirps too, I think. Anyway, I transferred to a nice fluffy mix of half perlite with fertilzer built in and half pro-mix pro formula. Then I watered quite fully. I will hope for the best. Temp in cab is good at about 81 or so.
Can anyone tell me how to post photos?
