As you can see...half of the tent consist of mature females and the other half is clones... (2) 600w HPS....maxfan with can filter...approx. two weeks into flowering...what has been your best nutes when flowering?
try fox farm tiger bloom, big bloom, but my personal fav..."BEASTIE BLOOM"!!! 0-50-30...really high levels of phosphorous(P) and potassium(K)...just what a budding plant needs!!!
Good Luck, hope this helps!
