thanks man, i love a coco grow, hydroponics in a pot!
i use these products
canna coco profesional +
canna coco a+b (leave it out for the last 3-4 weeks of the plants life)
canna rhizotonic (use until 2nd week of flowering)
canna pk 13/14 (use after 3-4 weeks of 12/12 for one week)
atami bloombastic (use for the last 4-6 weeks of the plants life)
i stop using all products 2 weeks before the end, i run 2-3 times the amount of water through the pot than i normally would to try and flush out any nasty chemicals.
i've got 7 different strains in my tent at the minute so feeding has been a bit of a pain in the ass, some got burned and some stayed hungry so no more multi strain grows for me, strictly one plant per tent from now on.
