Leaf Tip Curl? w/ pics

[tybeet]

I planted the seeds about a week ago, and I've been using 20-20-20 nutrients with an indoor grow setup and blueberry/C99 seeds, but the tips of the leaves have been curling since they sprouted.

And as you can see from the pictures there's no browning or any other sign of deficiency, but what is this curling -- does anyone know? Thanks.

it dosn't matter. The seed leafs dont matter at all.
they will die off in a few weeks. dont worry about that either.

your plants look happy.
but i wouldn't plant them all in the same pot
oh and dont give them nutes for a while

also ..more light

[tybeet]

thanks.

and why no nutes?

They're not ready for nutrients yet. Wait until they have at least 3 internodes or otherwise,until growth begins to slow. Even then only give them small amounts at first.

i hold off nutes for atleast 3-4 weeks, and still get overnute problems, so yeah hold off on them, i would wait another week from those pics to decide if there is a problem or not

the tips of the leaves are either curling because there trying to keep cool or over watering or its like harris7 says it dosent matter.. whats the temp? try to keep it to 80 - 82 if you do the 24 hour light cycle if you do the 18/6 light cycle try to keep it at 80 - 82 lights on and around 68-72 lights off.


glad to help

kb420, until you get more experience you should not be giving out poor advice.

1. Cotyledons pretty much always look like that. There is no unusual leaf curl going on.

2. The problem with those seedlings is multiple plants in one pot plus no tenough light, which is why one needs to be held up with a chopstick... at transplant, they can be buried right up to the cotyledons and will grow roots from that part of the stem so it's going to be okay.

3. You are lucky there's no browning yet but lay off the nutes to keep it that way.

4. Actual temps you need are a) not dependent on light cycle and b) lower than kb420 stated; temperatures at approximately 72-76 degrees F with good fresh air flow are ideal.

So your job now is to give them good air flow, MUCH more light, and as soon as they are a little stronger, carefully repot them into seperate pots. And no ferts until you see that the leaves have at least 3-5 fingers each, and at that point, start with a 1/4 strength solution for the first couple feedings.
