I only use AN (except for PK).
Don't believe all the haters...when it comes to growing you need to go through the trials and errors like most things in life and find what fits you.
Follow a AN Schedule but DONT use as nutrients as they recommend.
A must (IMO) when growing is a EC/PPM-reader & PH-reader.
Tricky part when growing is knowing how much EC/PPM the plant needs, cause some plants need alot and some don't need as much.
But with some tutorials, watching the EC/PPM and PH, you basically can tell what's going on.
Wanted to show you one if not my favorite strain and her beauty. Like the title says, day 57. Gonna flush her soon. Buds are hard as rocks. One plant in a 1mx1m (maybe similar to 3x3?) tent. Scope-375 Full spectrum LED from DiyledUK 70L DWC tank (18 gallons). BOYU L-075 Water Cooler Nutrients...
