Preventing Nitrogen Deficiency in Clones?

So after a couple rounds of cloning I've got a fairly good success rate, but I've found that by the time they root they are suffering from primarily a nitrogen deficiency but I'm sure there are more deficiencies than just nitrogen. I'm curious as to what you guys do to give them enough food to make it through the rooting phase and to transplant without any leaves yellowing or dying.

One method I've read of is soaking (in my case, rockwool) cubes in a diluted nutrient solution prior to placing your clones in. I haven't tried this due to the fear of over doing it and killing them off.

I do want to add, however, that my last attempt at cloning I have a 16/20 success rate and previous to that 6/6, but some were just healthier than others.

what I do is I feed my mother plants a lot of nutrients its on the strong side . they are very dark green . if this is not an option . then you can get a cloning solution follow the directions its basically nutrients that are very week . you can add nutrients to the water if you start seeing a problem . suggest a 1/4 as strong as you feed the plants . this will keep them green and still form roots . hope this helps you out .

Ensure you mother is in peak condition before you snip

foilar feeding during cloning I have done

I don't feed the stems/roots as often their is nothing for the uptake

and often results in bacterium buildup (snot)

good luck

@vostok has the right of it. Soaking the cubes is just gonna give you gross bacteria shit on your cubes. Keep the cubes moist for sure...but you wanna foliar feed your leaves.

Something with phosphorus, and magnesium but a bit of everything else too is nice.

I've had good results with fish hydrolysate, organicallydone.com makes a great one.

I've also made teas with Alfalfa Meal, and phosphorus Bat Guano but with how frequently I like foliar feed clones (daily) it's a little more hassle than its worth.

Fish hydrolysate does just fine. Put maybe like a quarter of a capful in a spray bottle. Doesn't take much when you foliar feed.
