super thrive and b1 stuff does this..when i tested

not to confuse with thrive alive,

Plant (moslty fan leaves ) nut - nuk burn , or (turns yellow - small 20 % solutions), like pics in start of bog, in late veg , med term, and budding phase.

i say they dont work very well, even for early growth stages.


PS: GH nova, series is a good 1 part mix , for new ppl starting.
