panda those are very impressive collas. are those on a plant that has been flowered once or twice before? you are doing lots of things right to achieve that. remember there are many right ways to do things when dealing with plants. every grower has to decide which is the best right for you. I like to optimize the efficiency of my inputs also. peace.
hey guys. so I think I started the lucas ofrmaula talk and the reservoir changes so here is what has worked well for me. I use a method thats in between the extremes listed on this thread. I use the lucas formula at 0-8-16 in veg and in flower because no florescents are being used. I change my res and clean it very good once a cycle. I use this formaula and have had excellent results. The res is topped off with new nutes to bring back to the desired level of around 1000 at a .7 scale. I believe this works because the nutrient soup provides the exact ratio needed by a cannabis plant and therefore does not get out of whack or ratios if used the entire time. I even cheat this formula with good results by adding small amounts of additives at the right times and always topping off with lucas formaula to desired ppm. If you change your nutes weekly yes you can use more aggressive additives and soups because you always refill or remix it weekly. If growth and yield is your only variable this is the way to go. I use this method because when adding in the veriables of water consumption, labor, cost of nutes , and a responsibility not to dump a load of nutes down the drain or in your yard (it all gets into our water system) then this method is by far better for me. I get yields just as large as when I used to change weekly with lots of additives. I believe this is so because this method makes it extremely easy to keep your ph right on (extremely important) and have no nutrient deficiencies or nute lockout caused by overfeeding of one of the nutrients that is almost surely going to get to high when using a full nutrient soup with lots of additives. I use additives that are organic and hormonal like kelp extracts and gravity, purplemaxx, and bushmaster. The practicalness of this method is guaranteed good results. In theory the regular change method is could be better but in reality ive found it no better due to more ph fluctuations and nute defiiencies caused by under over feeding of specific nutes in a soup of many products. this method can be applied to any kind of nutrients and goes back to the needs of the plants which are needed in a ratio for the cannabis plant of 100-100-200-60 in npkmg. all nutrients can be applied in this ratio with a little research th gh products of micro and bloom with 8ml and 16ml per gallon respectively are an inexpensive and easy way to achieve it. remember the recomondations on the label are for any plant not a cannabis plant. that being said all strains are different and you might need to raise the amount not the ratio for a given strain. wow that is a long reply. lol remember keeping the earth clean is all our jobs for our generations to come.
Thanks. You raise a couple of good questions.Good stuff, notavailable!
Just a couple of things,
do you need both the sm90 and hygrozyme?
do you need to use FloraNectar during veg? What does GH say?
the Diamond Nectar (fulvic acid) is good only during veg to my knowledge
with all of those additives in Flowering, is that your total ppm? With stuff like the Kool Bloom powder, you really have to cut down on the Flora series nutes.
HTH
Hihey Widow, that's a nice looking soup recipe. One thing tho, that hygrozyme is good stuff to use, and the bcuzz organic additive, both are being killed off by the h2o2. Those things have a hard enough time with the chemicals in the soup, they don't need the peroxide. Why are you using it every watering?
