Slow Growth

[asap]

I Currently have 5 WW from seed and they are all about 60mm tall and started to develop their first set of true leaves but they have stopped growing upwards over the last 48hrs is this something that I should be worried about or perfectly normal?

They are in 4" rockwool cubes and under 20/4 propagation lights and the temps are at 70F ish all the time.

Im new to this and probably just over thinking

When you say WW I assume you mean white widow. I am not sure how tall 60mm is but they should not have stopped growing for 48 hours. If they have stopped completely then something is surely wrong and I would start by testing ph then adding nutrients. If they have stopped growing up but not out then I wouldnt worry to much. They are still young and will catch up.

Also I would increase your temperature to between 75-80F and reduce your light to 18/6. It has been proven that there is no significant difference having the extra couple of hours daytime but the added dark hours will likely help the plant more.

Thanks I will increase the darkness by two hours then and 60mm is about 2.5 inches and I have been told not to add any nutes yet because they are still too young. I will also work to raise the temperature slightly too, the temps are generally 74-80 with the lights on and 68-70 with lights off.

oh and how do I test the PH of a Rockwool Cube?

Ok my temperature is now at 78F and when I looked very closely to the leaves I can see two more leaves appearing on 4 of my 5 plants although they are tiny! Im a bit more relaxed.

slow growth could be from many things, over watering, temp flucuation is to much, root proplrm, ph is off, and are you feeding it properly. i may of mist a couple.

 

[asap]

Well I think it is slow growth, i may just be being impatient on my first grow. They are 2.5 inches tall and have been growing from seed for a week.......

Im at the beginning of my first indoor grow with the same results. But mine are just some bag seed. Its really frustrating to see pics of these guys with week old plants 6 inches tall with three sets of leaves. Im patiently waiting but it just keeps coming into my mind im doing something wrong.

 

[asap]

Yeah I think it maybe then and some people may just exaggerate the speed of growth they really achieve. that's what I'm hoping anyway.

Im having the same exact problem with my one week old seedling, but i have Nirvanas Wonder Woman strain. Did your plants turn out fine?
