Is this normal after topping? (pics)

Hello everone, and thanks in advance for any help.

Just topped my plants 6 days ago, and after a few days 2 of my plants leaves started to curl under a bit.

This is my first -Real- grow with good genetics, so I wanted to make sure I wasn't doing something wrong. 1 of the plants is Blue Moonshine the other one with curled leaves is Chocolope.

Variety - 3Blue Moonshine, 3Chocolope, 1Super Skunk, 1Purple Lady, all femenized seeds
Plants age - 5 1/2 Weeks from seed
Nutes - Humboldt Organic line
Medium - Pro-mix
Lighting - 400W Metal Halide

1st pic shows the drooping leaves, figured I would throw in a canopy shot to see what everyone thinks.

Thanks again.

they look fine dont worry about it. sometimes on my girls they droop sometimes they reach up, sometimes both lol. might just be over watering or not enough watering

Check your water make sure your ph is set, Other than that I think it might be thirsty.

Thanks for the replies, I checked the runoff PH last night and it was at 6.2. I use RO water on all my plants, and really PH has never been a problem, even with the crappy bagseed I have budding at the moment.

As far as over/underwatering, I usually try to do it by the weight of the bucket after the top layer of soil starts to dry out. And when I water I just fill the buckets to the rim and let the water soak down. Sometimes I have runoff and sometimes I don't. Does that seem like a good way of doing it? If not, any suggestions?

Thanks again.

Sometimes this can happen but not very often but it is nothing to worry about blood.wait till you are chopping the plants and you have two nice nugs where one would have been.i personaly am not 100% sure that alot more weight is gained by topping.i have topped 2 plants and left 2 to grow on has normal the one that i did not top just had one bud on but it was has big has the two on the topped one.i must admit i always top harf my crop and leave the other to get on with it it's self and both produce simular weights.

i've noticed that leaves start to curl like that if your over-feeding. make sure your giving at least 1/2 the recommended dose on the label...even less when they are in a soil medium
