while I have your well tuned coco ear brother.. im currently feeding this girl every 3 days.. it seems to be all she wants.. should I start to close that in to every 2 days now or just keep on as I am until its clear she needs fed more often than 3 day intervals.. I feel like it should be feed at least every 48 hours for her at this stage??
Bloody hell, your thread moves at a rapid pace, I had to look back 3 pages to find your question to me from yesterday!
I'm feeding mine every 2 days at the mo. In the past I've tried various schedules, from daily to every 3-4 days, and I found that too much too soon does something to the Coco (I think it washes out the Potassium from the Coco - but not sure).
Too long between feeds and I started getting difficult to manage deficiencies - I think it's because the plant takes up the nutrients it needs, plus water, which raises the concentration of unwanted nutes in the medium, then the plant slows or locks down because of the change in medium EC and pH, toxicity from the unwanted nutrients, and deficiency of the wanted nutrients.... you get me?
Each time I feed I add a bit more. Going back to when I transplanted them from Solo cups to big airpots (day 14 ish), I would just water around them with no run off, every 2 days, gradually increasing the radius of the watering zone and the quantity of nutrient solution each time.
To help prevent salt build up in the medium, I use House and Garden's 'Drip clean' at 0.1ml/L, very economical, but you have to use it all the time right from word go.
By around 24 days, I was watering to full pot diameter and getting a trickle of run off, and now at day 28, I'm watering to full run off.... still every 2 days, but once I find I'm giving them around 4 to 5 L, I'll start watering every day.
From that point, you can theoretically water them as often as you want, You'll be replacing what the plant has used, thus keeping the available needed nutes at peak levels the whole time, thus getting massive growth..... easy to forget that Coco is a hydroponic technique.... the more you put in, the more you get out.
To be honest, I dunno why I'm bleating on like this, you are doing brilliant stuff mate.... you asking for help is like Stephen Hawking (RIP) asking which planet comes after Mars!
