Clones should not be fed nutes until they are 4-5" tall
You didn't say whether or not your MG is the type with nutes
already in it, if so you are over nuting them, especially if you're
adding other things to the mix
I would guess that you are over-mothering them, you need to
sit back and use the K.I.S.S. system
I use unfortified MG potting soil to clone with in Solo cups,
then transplant to regular fortified MG once they reach 4-5 inches or nodes
If you use fortified MG for your growing medium, you probably don't really
need extra additives for a couple of months. MG states the nutes last longer
than this, but mj really goes through the nutes faster.
I use the regular MG mix @ 1TBS per gallon of water every fourth watering, switching to a higher NPK
tomato type nute for flowering and budding, introduced at 1/4 strength
and increased by 1/4 weekly until full strength. If you try feeding faster than this, you will over nute
as the plant needs to readjust to the increase
I know this isn't what the big boys use, but it works very well for me
I tried to look up impotence on the internet,
but nothing came up.
