Leaf discolouration

Hi, I have a plant that’s been growing about 6 weeks now, my first attempt at this. There are recently leaves that are concerning me as they look very unhealthy. I am wondering what I can or should do to resolve this. I have added a few pictures to help, here you will also see a lace helping to support it as it was struggling on its own. I water the plant ever second day or so.
The strain is ‘critical feminized’ from royal queen seeds.
The medium is lightweight multipurpose compost.
The pot size is 18cm (top) x 16cm height and 12cm base.
The water i’m using is bottled water that says pH 7.
The lights I’m using are 2 CFL household bulbs, one says 23W->110W and the other I’m not entirely sure as it says 14W but I’m not sure what that equivalent is. Both bulbs are placed roughly 12-14 cm away from then plant, at opposite sides.
I have the lights on 18-20 hours a day for now.
Unsure what the room temp is but I will try find out ASAP.
Thank you for any advice in advance.

It's starving. Answer the questions in my signature so people can give you advice. Nobody can help you without knowing all the details for your grow. That said, it looks like you are growing in coco, which requires constant watering and feeding.

Hi there...I wonder if you could give some info on your grow so that the forum may help a little better?
Plant strain
Medium and pot size
Ph of water/ feed
Lights- type, wattage from wall, hanging distance
Rh
Ambient room temps lights on/ off
FF

Also using the wrong knot to hang your plant in the last image. Use 13 wraps to keep the fit properly tight.

Was it the plants idea to take an exit? (sorry, could't resist. I'm sure with counselling it will pull thru)

It looks like it's reaching for light and looking for food, I'm sure folks will get you on track with the info they need.
It's tough to learn to read a plants needs until you have had a few incidents. This one is can be saved if you have enough light.
Your other post mentioned a couple CFL bulbs

Hi, thank you for the reply. I need to research more as to what to feed it and hopefully I will learn here. Yes, I’m still using 2 household CFL bulbs, should I increase this? Thanks again!

I’ll keep that technique in mind! I dread to think there will be no hope for the plant and her problems and this may her only option out.

It’s likely too cold, too dry, not enough light, and too much water. Now that it is spring find a good hot window and have the whole container and plant in the hot sun. When the sun goes away find a warm place and put your lights on the plant. Put them 4-6 inches away from the plant. Maybe start out a little farther back and work your way closer. Find out more about your soil to determine how much nutrients it has.

Yes, in my opinion you need much more light than that. Here's a LINK to some info on lighting.

That soil mix is light on drainage (add perlite and more drainage holes for the pot next grow, pot roots love air ) but it looks like decent stuff to have gotten you this far. The lack of drainage is what is leading to drooping leaves. More drainage means less time for roots to drown, more time to grow and more constant feed cycles.

Looks like a coco/ peat/light perlite blend, maybe with added compost for ferts.
The stems look green, so PH is in the good range. Mostly need light fertilization, some cal mag and better lighting to keep going.
The CFLs are good for seedlings, but don't have the coverage a 100watt cob LED puts out since half that energy goes to heat.

And go to growweedeasy.com and read their library.

Same kind of leaf damage is on this plant, and an added PH issue here (see the red stems and petioles)
I accidentally fed them at EC levels instead of PPM levels for a while. The EC pen was set to the wrong mode, so half strength.

Then watered to correct it, so drooping leaves, fading color and leaf necrosis from calcium deficit.



Still recovering using these dirt cheap LED panels. Over watered and a bit burned from the surge of food.
Look at the plant structure you get from LED vs CFL, these limit the stretch nicely but lack the heat and spectrum of cfl for seedlings
These transition plants nicely to outdoor or flower tent but lack spectrum and enought wats for an entire grow.
These are 7000k, 20 watt panels from YesCom China, $22/ea. Fit perfectly on top of an aquarium tank for a miniature greenhouse

Hello, what do you mean by your signature? I’m growing in a coir compost which claims to oxygenate roots and provides slow-release fertiliser. I purchased “Westland Concentrated House Plant Feed” and I’m considering using some of this. Thank you for your help.

Thanks a million for your help. I have a very limited space to grow just one plant and I don’t think I have the space for panels nor do I know anything about them so I was hoping to use multiple CFL bulbs and add some more 110W ones, but would you suggest I scrap this approach and try and make something work with LED? Thanks for the help again!

Sorry, I realized nobody could see my signature on mobile, so I removed it. The questions Freddie asked were similar to what I had in my signature. I've never grown in coco, never mind coco with compost, so I wouldn't be much help to you. Hopefully someone with experience in that type of medium will come along to help you out.

Hi, how often would you suggest I water it and what can I do about it being too dry? Sadly, placing the plant on a windowsill is not an option... The medium I’m using is lightweight multipurpose coir compost and it claims to have slow-release fertiliser within. Thank you for your time!

Ah well, thank you for your time anyways! I still have 2 seeds left so in future what medium would you suggest I use as this seems to be uncommon and I don’t want to use it next time. Thanks again

I did my last two cycles with ProMix HP w/mycorrhizae mix 4:1 with perlite and I loved it. I'm trying a living soil, all organic, grow this time to see which I prefer. The ProMix is great for people new to growing, IMO, because it doesn't compact too much, like some other soils, and it drains well with the perlite added. Before that I used a 50/50 mix of Fox Farms Ocean Forest and Happy Frog, but I liked the ProMix HP a lot more.

You would be better off with a bunch of cheap household LED bulbs than adding more cfl ones.
You need at least 50-100 watts per plant, Don't use "equivalent" watts for anything, that just confused everything.
You have 23+14 watts of cfl....37 watts that is 1/3 heat, so not much lumens and not the right spectrum going forward.

The plant will stretch more to a single light, so use several cheap work lights with 3-4 way splitters for 45-60 watts per fixture.

What are the dimensions of your grow area?
