Adding nutrients to DWC

Just a few quick questions...

How often do I need to ad nutrients to my water?

I am going to start my seedling at 1/2 strenth, so I just ad the 2nd half when its big enough or do I ad full strenth at that time because the intial nutes have been used up?

Do I ad a dose of full strenth every week after that?

Do I try to constantly mantian a specific PPM?

Do I ever need to change the water completly?

In the last week of flowering they suggest flushing to remove chemichals from the buds... Is it adventagius to change the water completly or just stop adding and let the plant aborb the remainder without fruther feedings prior to the final week?

Thank you, I searched for these answers and coudlnt find them.

anyone anyone... buler?

start at 1/4 strength after at least two sets of leaves appear. Slowly increase each res change

top off with plain ph adjusted water if level drops too much between water changes

I change mine weekly, but you can go 10 to 14 days if you like.

Go on the light side of what your nutrients recommend, and like I say start really slow and slowly work up.

Way better to under do it than over do it.

hey dude i've just started my seedling 2 weeks ago on an e.c 0f 0.5 first week and 0.7 second week and they are now about 3 inches high and 4 wide i change my res the first 2 weeks then every 2 weeks after that u can check e.c and ph daily depending on your rez size and i flush with final phase from advanced nutes first day of flushing then plain water not even ph'd for 9 days hope this helps

How often do you add nutes?

hi ive jus started my seedlings a week ago and was wondering if i build up the food weekly starting with 1/4 it will take 4weeks rite..
what happens after that if i need to carry on with th same food??
please help..cheerz

Just give nutrients at the same level each time you change your res. Up to you if you top of with plain ph adjusted water or water with nutes in between the res changes. When my plants were small, I used plain water, as they got bigger I topped off with water and nutes, making sure the nute EC wasn't too much.
