Check your soil Ph.
Always check your Ph before you go off and get mental and add some nutes. Because, someone said it was a nute Def.
Sucks to create a hot soil condition and find out later you had a nute lock out. Then correct the Ph and Boom all hell breaks lose.
Grow smart.

thanks for the advice !
