A question from a fellow grower:
I cant even clone cus all my plants show signs of something toasting all my nodes would azamax do it. it says its doesn’t hurt plants. This is a problem. My plants started to veg, but it just turns yellow i was looking on line it said i needed ebson salt but i figured id ask you because you seem to have the knowledge 
It would help us a lot if you told us what you have that plant in.
Was this plant rooted already? If not; Placing it in a pot of soil is OK. If not and you add nutrients to an unrooted cutting; You will fry it :oops: Remember; It is a cutting until it roots, and show signs of growth; Them it is a clone.
Give us a little info. IN the meantime; If it was me…I would top that plant. The yellow top is done. Sorry to be the bearer of bad news. Peace
