Is this Magnesium defiency or something else?

she’s hungry, feed her every watering, only water from the top..
your over mothering.

Thanks for info, no coco though, only soil and perlite. Might look like coco cause I have watered from bottom for 10 days or so

How far away are your lights?

 

[Weedlogger]

does it get any darker as the day goes on? is it lighter when it first wakes up? or any other combinations...

have you noticed anything along the way, i mean, it was ok for a time then it turned, or it was always lighter...

the very first time you noticed it lighter did you do anything in the 24 hours prior that was different? unique to this one?

did it start after a good watering or feeding? or after the dog barked at it? <--- just seeing if you are paying attention

Same color throughout the day. When I first noticed the new limegreen shoots I gave it nutrient water (even though it wasn't really in need of water) but it doesn't look like that did anything as it hasn't changed much.

It started a couple days after it's 3rd feed, when it had about 3-4 sets of true leaves depending how you count them.

Have fed her all watering sessions except one watering after this issue had developed. and this started and developed when I watered from top. If anything it looks better after I started bottom feeding, even though that might not be related

Roughly 25-30cm

Also I forgot to mention that the leaves that have this limegreen color is dry to the touch and a bit rough as well, as if the surface of the leaves are uneven, like blistered skin

40-60k lux is waaaay to much. These ladies are not capable of that kinda light intensity at this stage. 20-30k at 18/6

40-60k is good for a mature plant in flower on 12/12.

Thanks I'll raise the lamps, it's funny because I have 3 plants, and the one that has gotten 60k all the time is the healthiest, but it is another strain.

Roughly 25-30cm

The par output differs form light to light but maybe try 50-60 cm for now. Once you switch them you can lower them to increase intensity

What type of light do you have? LED?

 

[Weedlogger]

Yeah the producer says 20-30 cm for peak performance, and yes they are LED. Quantum Boards from Horticulture Lighting.

Raised them to 50-60 cm now. Let's hope that helps!

Yeah that was way to much.

What's the lux now? I'd prob go 20k and let them recover and get the watering and nutrients sorted a bit before bumping up. But likely that was the cause.

 

[Weedlogger]

They're 25-30k now, I can raise them a bit more.

This is one of the same strain at 50k, it's a bit smaller but is just barely exhibiting the same symptoms.

 

[Weedlogger]

And this one has had 60k all the time and is another strain. Looks a bit bushy (and I just pruned it, gonna do more in a day or two)

Oh yeah light stress written all over it.

What media? Looks awful dry?

75soil-25perlite, and I've bottom fed the last 10 days ish. it looks dry but it's moist 1-2cm down. Was trying this as I had problem with fungus gnats on the last grow

See how the leaves are cupped and the serrations spiked?

Water with BTI mosquito dunks and toss up some yellow sticky pads for the fliers.

Yes, is that a guaranteed lighting issue?

Just dissolve them in water and use that water for nutrient mix when I water?

Yup prob once every few weeks is good.

And yes that cupping is light stress the leaves fold to reduce light capture.
