Ok so i guess its my fault, but i found out today that foxfarm is shitty for hydroponics and is specialized for dirt. I found out that they put out the hydroponic grow but truly the formula is bullshit. I always have defficencies with FOX FARM and am fed up with it. Im always having to use ADVANCE NUTRIENTS stuff to fix problems. Fox farm is truly over priced and bullshit. Ive sent them pictures and had no response from them. Im so sick of the product. I could see if it was a good started product for somone new to start out with but its complete bullshit. You are destined for failure. Im not saying that i didnt have a successful product with it. I had some great smoke but yields were not that great. I have talked to many many growers who have said they started with fox farm and they switched to AN or Humboldt. Im so fucken pissed i didnt switch earlier. Fox Farm is good for maybe vegging but their shit is weak and imcomplete for flowering. So i suggest ditching fox farm if you are in hydroponics. Just so you know and their is no confusion i have followed their chart to a T with OPTIUM condidions with c02 enriched enviorment. Were talking the best clean enviorment with maintained c02 humidity and temps. IM DONE, IM DONE WITH FOX FARM. IM SWITCHING TO ADVANCED OR HUMBOLDT TOMORROW AND IT FOX FARM HAS LEFT A SOUR TASTE IN MY MOUTH. FUCK FOX FARM, FUCK FOX FARM IN THEIR STUPID ASS
I was having similar problems as you with FF for my nutes so I did some searching around & found this on MarijuanPassion.com's message board. It's for the original nutrients+additives but it's a lot weaker than their schedule recommends. It's worth a shot & it might just work:
Very Simple & Very Safe & Effective Fox Farm Nute Chart for Hydro Systems:
Many people that are new to a hydroponic system have no idea on how to feed their plants, and they get a million different answers from a million different people, then they get even more confused.
The chart below is one that I made myself and its for Fox Farm nutes only.
I learned the hard way that the FF chart given with the nutes is no good for most strains and will burn, kill, most plants specially in their early stages, so I decided to experiment with varius levels of nute strengh, and found that this chart works the best for all the strains that it was tested on, I use tap water because my tap water has a low ppm.
This chart is a very safe chart to go by, no worries on over feeding the plants, wich can cause some serious problems either right away or long term, it has an initial ec that is low, then moderate, then high.
This chart is for a 4 wk vegge period and an 8 wk flowering period, if you were to use this chart, and vegge longer than 4 wk's all you need to to is continue following the chart as it goes into the flowering chart but continue to use the grow big, versus the tiger bloom, that's all, very simple, and dont use the solubles, the solubles are for flowering only.
If you flower for more than 8 wk's all that you need to do is continue following the chart from wk 12.
Has the ec is raised the ph will remain more and more stable, I recomend using distiled water, for the first 2 to 3 wk's of the plants life then tap water can be used IF the ppm is not to high, if the ppm in your tap water is high either cut back on the nute solution on this chart by 1,25ml per galon, or continue to use distiled water or RO water.
I also recomend using 1/2 cup of hydrogen peroxide for every 20 galons of water twice a wk ( every 4 days) I found it helps keep the roots nice and clean.
