Cloning problems

[Slytiger]

I’ve got the tops from a set of plants that I’m trying to clone and set to flowering mode so I can tell if they’re male or females. I took the clippings, dipped in rooting powder, then right into spring water. They’re getting 18/6 light, 78-80 degrees temp. & 75% humidity. They’ve been in for a week and they were growing good and vibrant but in the past couple of days the upper leaves have been yellowing and cupping.
Does anyone know what could be happening?

Hi, Slytiger.
I am not a cloning expert, but would guess that you have too much foliage for a rootless clipping to support. My own experience is to strip off all but the top leaves and then cut off the top half of these remaining leaflets. This greatly reduces the vegetative material the clipping has to support while roots are forming. I'd look up GWE's cloning tutorial for further guidance. I have have successfully cloned cuttings in a solo cup on my kitchen table doing it this way.

The plant is eating itself due to no roots. Once roots form they will perk up, but I cut the "mother" leaves as soon as the clone starts growing it's own leaves. With clones it is a race to grow roots before the leaves are used up.

I agree with the others.

Am almost foolproof method is to use an aeroponics bucket. Easy and cheap to make yourself and 100% success rate is typical.

Thanks much for the advice, I’ll try trimming off some more leaves. Maybe re-dip in gel and put in new water. Should I use a little sea kelp?

BTW - I am following Nebula’s tutorial (guess I need to follow it more closely)🧐

Idk about sea kelp but the juice from a fresh aloe in the water will help. It contains hormones that will stimulate root growth. Just squeeze the aloe leaf until the slimy liquid comes out, leaving behind the pulp and mix in the water.

My 2 cents for what it’s worth. After I clip the stem I dip in rooting hormone then I put them directly into a growing medium small cup or pot I have good luck with sunshine mix4 or happy frog. Then I just leave them in bright room for about 2 weeks then usually they have roots by then..

What is critical is the time between the cut and the time to getting it into solution, whether that be rooting hormone or nute solution, it just needs 100% humidity at the cut. Seconds count here. A few minutes and you may not recover them.

Well I did some big time trimming and removed the lower and fan leaves. Also changed out the water - 5.9 ph I didn’t have any aloe or clonex gel so I just added a touch of sea kelp. 78 deg. 75% humidity. Here’s the pics of my butchery.
