Leaves curling, HELPP!!

[Gormzz]

Heyy guyss,

Ok so im growing 4 plants of the G-Force strain in soil nd its under a cool and warm white fluorescent globes. Originally grew the plants in plastic cups until the roots became to large for the cup, hence the transplant into the bigger pots (refer to images). I purchased seasol powerfeeder for fertiliser (australian) and added a dribble (no actual measurment) to about a litre of plain tap water i was feeding the plants previously.

I ran the initial grow under 24 hour light and continued to do so until the roots became to large for the cup, around the same time i noticed a couple of the plants' leaves were beginning to curl(refer to images). I thought possibly they were receiving too much light so i have now reduced the light period to 20 hours / 4 hours. Not sure what else????

Pleaaseee Hellppp diagnose

Thanksss

how hot does the light actually get?temps etc? they still produce heat also is there a constant supply of fresh air?
is there any discolouring to the leaves?

Honestly I don't think I see much wrong with her :thumbsup:
Maybe be very careful about how you go about adding nutes to her for now because she is still quite young.

Hopefully someone else can give you some-what of a better answer

Get those yellow things out from soil. Can cause problems in future.

to be honest it looks fine to me mate but i wouldnt give it nutes till its a bit older

[Gormzz]

as for how hot it gets, with out a temperature guage, but it wouldnt get much above 30 degrees Celsius, but most days being mid 20's celsius.

there is no constant supply of fresh air, but i do have a little fan going to circulate the air.

The older leaves do seem a lil duller when compared to the new leaves that are growing.

As for the nutes, should i completely stop them and do a flush or just stop them now? when should they be introduced?

and could i bump the light period back up to 24 hours or should i keep it at the 20 hours / 4 hours cycle?

sorry for the newfagg questionsss

thanks guysss

I had the exact same thing happen to my plants first week and a half, they turned out fine.. first sets of leaves were a little curled, but after that they were fine.

For light period, i'd stick with 20/4. everyone has a different theory, but i like having a little dark period because its a little more natural AND there are physiologic processes that only operate in the dark cycle.

For nutes, everything i've read says dont give nutes in first 2 weeks. and then start very small and build up slowly, giving nutes every other water, not every water..

thats just my inexperienced opinions..

I've seen quite a few people question deformed leaves on seedlings, myself included. I believe the problem that you have isn't that serious at all. If I'm right it's cause by your soil having good amount of nutrients in it to start with. In other words the soil is a little "Hot". I've had the same trouble using Fox Farm Ocean Forest. Things go back to normal after the seedlings reach a week or 2 in age. If these curled leaves bother you too much, next time try doing a minor flush of the soil before you start your seeds(this works as long as you aren't using a heavy time release soil such as MG 3-6 month formula.):thumbsup::thumbsup:

so when i take out the nutes, do i need to flush it first or can i go straight off the nutes with the next watering?

also with the watering, my method is to water when the soil becomes reasonably dry, is that right? or is there a better way of telling when to water?

thanks heaps for the help guys :thumbsup:

No need to flush now, I'd just stop with the nutes for a week or 2. Most people when they grow soil don't even start with the nutes until flowering. Most soils have enough nutrients to go for about 2-4 weeks after each transplant before its starts to become necessary to add ferts(this can change depending on if its a time release fert soil, such as MG 3-6 months.) You've also got some kind of ferts in there already (little yellow pellets that tevfik recommended you remove.)

As far as watering, lift the pot when completely dry and then lift it when you just watered. This is the method most use for determining if they need to water or not. I still use this method with my 3 gal pots.:thumbsup::thumbsup:
