How Should i treat ??

[blanchdave]

I'm thinking i might need to treat this white widow with epsom salts....

Its 28 days old and was put into this bigger pot with allmix 1 week ago.
I started using biobizz bio grow straight away (perhaps too early).
Its growing with 2 other plants (Maui wowie and G13 Armageddon) and both of them are in perfect health.
Their under 4 36w fluro's and i plan changing them to 12/12 under a 400w hps on october 1st.

If i do need to treat with epsom salt, what dosage do i use ?


Thanks
