Here's my grow journal: https://www.rollitup.org/grow-journals/159411-first-cfl-grow-1-week.html

right now our plants are about 2 weeks into flowering. we've had a problem with the tips curling for a long time but i think they're getting worse.

now more and more leaves and folding inwards and are not spread out like they should be. These leaves folding inwards have been appearing for a week now. the plants suffered from fert burn a month ago so we haven't fertilized since then. we just fertilized yesterday with the big bloom 0.01-0.3-0.7 and we only used a half dose. we are using 6.5ph water.

what's wrong???? :-(

Does the type of soil you used have any ferts in it already like time release ferts?
yea, we transplanted a month ago into foxfarm ocean forest. i don't think it had time release fertilizer, it's organic soil. these curling leaves haven't appeared until a week ago.

lower your ph to 6 - 6.2 and try adding a little bit of molasses to your solution, less than a teaspoon a gallon

could be a few things ..

low humidity, but during flowering thats good .
overwatering.
magnesium deficiency
our humidity is around 55%, we are watering every 3rd day when the top 2inches of the soil is completely dry. we don't know about magnesium deficiency though.

almost every leaf's tip curls down, but that's been an issue for over a month. the new issue is the whole leaf is completely curled and folding into itself.

ya I got one of my flowering kush plants doing the same thing, and the top leaves are reaching up, but the other plants are fine, so im not really worried.
you could always take a look at the roots, but I wouldnt worry too much. Most of what you read on here is B.S. anyways, it is a weed, that'll grow in pretty much anything

If you can get some more photos a little closer for me. What leafs are affected by this? Such as new ones fan or top. How do the leaves feel to the touch? I think the tips a browning but It is hard to see the other parts from the photos. If you can get more photos and help by discribing a little bit more I will be checking back a few times today for you.

From What I see I would say it looks like Nitrogen deficiency. Lower leaves are pale green or getting yellow?

every single leaf is green, but some of the top leaves are pale green. none are discolored or yellow.

none of the old leaves are curling like this. only the new top leaves that are growing out of the buds are beginning to curl like this, as seen in the pictures. it could be nitrogen deficiency because we haven't used fertilizer on them for over a month (they suffered horrible fert burn back then) because we transplanted them into the foxfarm that had fertilizer in it already

the leaves feel fine like the rest of the leaves on the plant.

right now, the curling is only affected about half of the new growth. almost all the new growth is pale green as well.

also, our plants temperature is kinda low because it's really cold where we live. it's about 55 degrees at night and 70 degrees in the day. is that too cold? should we keep a heater on at night?

i had the same problem......its most likely nitrogen def, it was in my case. i foliar fed em a tiny bit of 20-20-20 instead of my 10-50-10 for 1 feeding and my girl stopped it.

You don't want it gettin' any lower than around 55F . . . it's cold here, too. I've found that a small space heater, on lo at night, gives me that 5 degree buffer to 60, then the lights heat me to 75-80*.
I think you'll be alright as long as your day/night doesn't vary more than 15*F.

the new leaves being light green is perfectly normal. my girls are curling too but I would not worry too much.hope you have a happy good grow.

they look fine to me, in fact pretty healthy. Don't worry about any curling. During flowering I notice the leaves will start getting more and more unhealthy looking as the weeks go by. It could be so many different things. I got every problem imaginable with my leaves at week 4 of flowering. The buds are developing better and better with each day though so I just keep my fingers crossed and not worry about it.
