Plant curling, mystery problem

You'll know if you have aphids, look under the leaves.
You'll see them.
No need to panic, there are a million remedies for them.
But like you figured out.
They needed more room.

See.................. everything is fine and no need to panic.
There is plenty of help here.

Hippy girl is exactly right in her first post. Most likely one of those things she listed. +rep

Had the exact same problem with some vegging plants...found a flush helped. I had let the nutes/salts buildup too much in the soil pots so I flushed all my plants with pH 6 water. The flowering ones got the flush too but they almost fell over after because they are near harvest-had to support with sticks. THe water coming out the worst ones looked like yellow pee. I am going to do it to the veg plants again once they dry out in a few more days. I think it would be a good idea for you before you start seriously budding your plant.

Well its been like 4 days since the original post and while the bottom leaves are staying curly (probably already damaged - no aphids btw) the top ones have opened up and the new growth is lookin great . If anyone wants pics ill go take some.

Edit: Oh yeah, another question before i go: is it normal for the oldest leaves to slowly yellow and die off? Ive been told by other growers in person that it is but it seems like the general consensus on this site is that its not. If its not what could be the problem? I know for sure its not nute burn because im very conservative with my nutes, i wait til growth is being stunted to feed.

Also, how do I add rep? Theres a few people who really helped me out here who Id like to rep. Thanks!
