If you guys dont rinse or do water changes on the res, how do you know when to add nutes and how much to add ?
first off ihad real issues in the beginning by over complicating things. checking ppm, ph, trying to be real scientific.
scrapped that approached and tried to simplify.
first off, i pre-mix my res into one gallon containers. after adding the General Hydroponics nutrients and my Hygrozyme, the ph tends to be around 5-6 so i use that. i have some testers, but really only test it once a week.
i also, use the recommended feeding schedule as proposed on the back of the GH bottles of micro, gro, and bloom, as well as the hygrozyme.
if my ph is "out" i have GH PH up and Ph down to adjust.
right now i am into the 3rd week of 12/12 so my feeding is mostly bloom nutes.
ppm- i have a hand held ppm meter but stopped checking so frequently and just trust the GH formula. so far upon checking GH has been spot on.
so to summarize,
ppm tester - good to have
ph test kit with up/down adjust - good to have
correct nutes with guide for feeding schedule - helpful but many users go with AG nutes.
young plants 1/4 dosage
medium plants 1/2-3/4 dosage
mature plants/flowering 3/4 - full dosage,
least thats what i have read here.
check my gallery, you can see some things i have added as well as a sort of growth chart. sorry i am not too anal to right every minute of every day down. did a little of that in the beginning and had a hard time.
i better at winging it and watching the plants. they tell me what they need.
so far nothing but what i am doing for them.
