Humboldt sticky Reviewed by Humboldt sticky on . Nutrients and yield :cool: Howdy Fellow Farmers!!!I use General Hydroponics Flora Series, according to the GH chart...I noticed the ppm concentration decreases rapidly, to about 50% starting strength in 7 days...and then I change it... I also now see a group of additives listed on their chart, Diamond Necter/Chi/Flora Shield/prysol, etc.... My question is, "Are these additives cost effective", ie., are they worth the added expense??? Furthermore, are there other less expensive nutrients to use yielding the Rating: 5
