Organic fish fertilizer is a liquid you can get pretty much anywhere. I use a brand called Neptunes Harvest, but there are many and they all probably work the same. Basically it is a protein shake for your plant...stinks like hell! I usually add a capful in my watering every 2-3 time once I notice the plant looking hungry. Strains vary, so how much each needs depends on your judgement. I think the 2 weeks was a guesstimate and early imo. Also depends on the growing medium. My soil is potent and some strains thrive in it and some burn up. Only way for me to know is to run them and watch and learn. But the ones that like it get all they need well into flowering and often I don't even have to add fish fert.
Thanks mate I’ll look further into that and see if I can incorporate it into my grow, sucks I spent so much on nutes already though might head down the route of having no compost in my soil I’ll see how I go!
Good advice here. I'll jump in: flush them heavily with pH corrected water (2 gallons, 1 each an hour apart), then get a soil moisture meter and don't water again until soil registers "dry". This should take care of any nute burn. The soil meter will help you refrain overwatering in the future. Then start a nute program for autos. I came up with the following chart, modified from FF suggested feeding schedule for photos (my apologies to FF). Perhaps it will help.
Thanks for this mate! Appreciate it, just did another flush and going to repeat in an hour, she’s getting worse so I think overwatering is better than her completely frying up, I’ve always gone off the weight of my pot but I may just invest in a moisture metre! Cheers for your help and the feeding chart.
This is her today. Looking very sad but let’s see if I can bring her back!
