My babies are yellowing! What do I do?

[MMJ Mademoiselle]

Hi there! I am extremely knew to growing. I have a tiny grow of four afghani clones. Almost all of the leaves are beginning to yellow or lighten in color. Does anyone know the cause and how I can fix this or prevent it in the future? Thanks!

Can't diagnose probs without pics

 

[justugh]

first step is always the same with or with out pics

u need to test the PH of the soil/water
to test soil u get water .....u ph the water so u know what it is (6.5 is the golden zone) ......u pour the water into the soil and keep doing this until it leaks out the bottom ...capture the run off in a shot glass and test the PH of the water this gives u your soil rating

hydro systems u want 5.8 it golden zone

if the numbers are 2 high one way or the other u get nutrient lock out ......the plants roots can not absorb what it needs (this is most common cause of issues)

They are clones still in their rockwool cubes. Under 24 hour lights. I haven't transplanted them yet.

you have to actually give us information on your plant
tossing a photo is apart of the puzzle
everything oyu can tell us about your plant, your watering, your lights, anything
helps people help you

That looks like a phosphorus problem by the color of the main stem and yellow leaves.

Or maybe your light is too close ( bleaching).

Yellowing leaf on clone is normal, all energy are directed to the roots

OP,
You did not create the clones, correct?

With clones I go from a 1" cube to a 4" cube, I do that as soon as a few roots poke out the bottom.
I leave the wrapper on my cubes till they go into a larger cube the I leave the wrap on the larger cube till it goes in the substrate.

I use a food called Olivias cloning solution to feed.

Does that mean I should be giving them some nutrients??
