some Ppl. like to go on the low side in Veg. (5,6-5,8 ) and on the high side in flowering (6-6,2) so to speak, to make sure it can take up the necessary/important nutrients for the specific stages
feed every time, but use a deluded solution, maybe half strength as what the producers recommend, and take it a step at the time, both until you get the hang of it and also since it much better to under feed em compared to over feed em, much more easy to up the feeding then to flush the plant and a lot less stress on the plant, a small seedling in Veg. also need a lot less then a hugh plant in full flowering
A little tip, I often see Ppl. and did also have first hand experience with lack of Ca (Calcium) in Coco, as coco have a tendency to lock up Ca, so make sure to have a bottle of Ca/Mg+ beside the regular Veg/bloom solution, dolomite Lime and similar is not recommenced to use in coco, so get some liquid stuff, you can also get pure Ca, but the Ca/Mg+ also provide Mg (Magnesium) witch also play a hugh role in the development of the plant
