Tips of leaves slightly turning up

well I would guess at around day 4 or 5 it's not uncommon too see the roots at the bottom of a 16 oz solo cup. Hopefully that gives you a bit of a guesstimate.

yep, is either light or heat stress - also please check your pH - looks like "witches broom" symptoms almost.. could be lightly locking out Bromine

The reason I'm asking about the roots is because I put some light mix on top of the coco, I can't remember how much but it might be over watering cause the roots haven't reached the coco yet? At the time it seemed like a good Idea. It might also be lack of nutes cause they are still growing maybe not as much as they should.

The temps in my tent are between 24-26 & the lights are about 28 inches above the plants they were at 24 & 18 but I thought having it so close might be the reason for the drooping but they haven't really changed much from raising the light.

Temperatures are fine; can you get a PAR reading at the top of the plants? 28" should be plenty but can take a little bit to adjust from stress.

I only ask for a PAR reading because some lights like the Max Yield from Black Diamond can throw some serious photons - others use COB and Lenses in a similar fashion is why I ask - 28" could still be 900 micromoles or more which is 450-600 too many for seedlings

God knows mate i don't have the tech to measure that... All I know is that I have a LUMii Black digital dimmable 600w. What do you think about my medium situation with the soil and coco that I stupidly implemented into my grow? That might be the reason?

could be fungus gnats as usually follows coco - which will cause some issues with roots and could explain why development is skewed a bit.

next time you do this - add SNS 203 to the mix regardless. in the meantime get some yellow stickies to see if you have invaders - put the thing right at soil level on a Popsicle stick or pen...etc

now as you've used both coco and soil - you'll have to treat things as soil so keep your pH between 6.5 to 7.5 instead of 5.8 to 6.2.

add a little bit of sugar to your water if is a living soil (1tbsp of raw sugar or maple syrup per 5 gallon RO water)

make sure your water is good and clean - anything with counts over 200ppm will require a RO & Carbon Filter if in City and Chloramine and Fluoride are dissolved. both kill micro-organisms. Sodium locks out everything as Sodium is taken in first before other nutes - which is why anything over 200 needs filtered.

make sure to bring on CalMag if using RO, LEDs and Coco... about 10mL each so if you're using RO water, LEDs for lights and near 50% coco - you'll need ~30mL per 5 Gallons of RO water. always add CalMag before adding other nutes.. Autos love CalMag.

and keep your nutes about half of what photos would use (1/4 to 1/3 of what bottle says, work up to 1/2)

I believe that's a bit of a myth. Chloramine levels in most tap water only kills the bacteria suspended in the water and has little effect on the microbial life in soil.

Oh fuck fungus gnats!? Fuck.... Anyways thanks for that help mate much appreciated!
