a few leaves are curling up

[caregiverken]

I looked all over before stated this thread. and I can't find any pics that look quite like my curling leaves.

These plants in 4 inch pots are just 3 weeks old (from seed) the ones in the back are clones Ive had for about the same time

all are growing in Fox Farms ocean forest and were fed 1/4 strength nutes for the 1st time a few days ago

they are under 450w MH (bout 14 up)

Now we have a few curled leaves

any ideas?

Do you have any tiny flying bugs in the room? Check the roots, CLOSELY, with a loupe or something that will give you 10x-30x magnification. Those are looking like the classic signs of root aphids sucking the life out of your plants. The thing is, they're only a few weeks old, but still, they shouldn't be doing that.

If it began only after you fed, then I would use water only UNTIL they show they need feeding. I've never seen hot feed do anything like that (yet!).

No need to fertilize through the vegetative stage if you're using an already fert-heavy potting soil. You shouldn't need any nutrients until at least the second week of flowering or so.

Pots look too small also. Get bigger pots and use only pure pH balanced water and I suppose that your problems will disappear.

thank you for the replies Seamaiden and Doc

I haven't seen any bugs. But I will look at the roots with a loop when I transplant them to bigger pots.

Those 4 inch pots are the pots they started in (just been 3 weeks) :)

I'm thinking it was the ferts. and I will just give them water for a while.

Thanks again

Done deal :)

I also looked at the roots of the couple with curled leaves with a loop and didn't see any bugs.

And I read the back of the bag the FF OF soil came in and it said no fert needed for up to 30 days...so I guess I may have use ferts a little too soon. But only a couple plants seemed to have a problem.

Thanks again for the help. Reps to all that chimed in :)
