im not talking mineral salts, i meant plain old salt. Even coco coir has a high salt content due to the coco being so close to the ocean. You can use these fertilizers but if i were u id leech eevery 4 weeks if using something from the ocean
salt is salt. yes the kelp "meals" and fresh seaweed has not been processed much so the salt level will be a bit higher then the bottled products like liquid seaweed , which has no more salt then any other plant food , and it will be less because the numbers are so low.
even using fresh seaweed or kelp meals will not have a high enough SI to bother your plants. (of course you can overdo anything almost)
just like coco , the salt in a brick of coco is no more then a small bag of MG potting mix , or fox farm soil. (put a cuup of each in with a cup or two of water , let them sit for a lil bit then check the EC) my personal theory would be the good soil having a higher EC then the coco because there is much more available food/salt in the soil.
im sure youve heard this a million an two times , but a plant will never eat more then it wants or needs. (thats also why there is no such thing as "nute burn") so the extra salts will be stored in the plant cells until it needs them , and if there is still extra salt after that ..... you fed too much and the extra salt is going to lock out the water uptake. (ruining your soil and causeing death)
My general rule (which i should probably go by myself
) is to start with a very little amount of food then work your way up gradually till you see a little bit of curling of the leaves , letting you know they have just enough or a lil too much food and base your diet of that.
nizza, no kid bickering here , but what are you reffering to when you say plain salt ? the way i understand my books is that the ocean salt is the same salt thats in our foods. i may be wrong .....years of baking an xanaxing is slowed me way down.
