Give them the nutes once a week and any other time they need a drink it should be pH'd water only. I divide my nutes in two and feed twice a week and they get no plain water.
Plain water is for flushing, lol (or when the medium is 100% nutritionally complete). If one isn't overfeeding, those things don't have a chance to build up. There are still waste products, but they - and their concentrations in the medium - are a factor of plant growth, how they are fed, how much they're fed, whether its a sterile medium or an active biosphere, et cetera. My gut tells me that a
periodic flush is beneficial.
As for the feed / feed / feed / water , feed / feed / feed / feed, feed / water / feed / water, etc. debate... Many ways to arrive at harvest. Personally, I think that giving them milder doses with every watering is going to be better for the plants. We try very hard to ensure that our plants' environments do not vary. If all other conditions are kept the same from day to day, it is reasonable to do the same thing in regards to feeding.
Aye up guys, real noob question here but my feeding schedule is on a weekly calender however i water them more than once a week..
Common sence tells me follow the schedule not matter how many times i water but you never know....
Correct??
If it's hot and windy all day, your plant will use more water than it did the day before - but it won't use any more nutrients, assuming the same amount of light-energy falls upon it (well, this is not absolutely true, because one or the other situation might change the temperature enough to affect how much energy the plants can process, but...).
This stuff might be easier to get if the grower runs a DWC grow at least once, lol. Basically just the plant sitting in (hopefully) highly oxygenated nutrient solution. By monitoring pH and EC/TDS levels, one can easily see when the plant has used/transpired more water than nutrients (water level goes down, EC levels go up because there's a higher concentration of nutrients), et cetera. Changes that the grower makes tend to have a much quicker observational effect. And if there is an issue (other than plant death
), it's relatively easy to change the solution. People talk about soil grows (vs. hydroponic in general and, specifically, DWC) and how the soil provides a buffer - and this is true. But this can also mean that, by the time there is visual evidence of a plant issue, that the balance of things in the medium has gone wonky. Then the grower wastes (okay,
uses) a lot of water on a 3x flush of the medium. And that's
step one, lol. OtOH, a grower
can kill a plant much quicker in DWC than in soil. Accidentally add WAY TOO #%^&ING MUCH SILICON (don't ask :rolleyes3 ) to one's reservoir one evening, return to the grow room the next afternoon to find almost every leaf
on the floor... Stupid veg-head moves like that. But, in general, DWC can be great for learning this stuff because you see results to changes much faster and
usually can rectify mistakes quickly. And, assuming that you've got sufficient levels of dissolved oxygen (MAD amounts of DO should always be the DWC grower's first priority), I believe that a plant can endure higher temperatures than in soil; given the container sizes that we work with, and the root mass sizes, the act of transpiration appears to be easier. This can also mean that the seven gallons of water you dumped into that
very large plant's reservoir before you went to work are nowhere to be found when you return home that evening because the plant took it up and transpired that much via the stoma in its leaves (natural cooling mechanism) in order to stay healthy on that unexpectedly hot day. Water consumption rates can be surprising (and that's from someone who knows an acre of corn can transpire 3,000 to 4,000 gallons of water per day and that a single large oak tree can transpire as much as 40,000 gallons per year).
This has been an official ~TS~ ramble, lol.
