so i'm in week 5 of flowering and am running low on my supply of nutes... can i change the kind of nutes at this stage? it will have all the necessary nutes it will need. just changing from the nutes i got free from ezhydrokit when i bought my system and changing to Floratech Hydro. will this shock the plant? or will this be okay?
Give it a flush or use some florakleen to flush before you change your nutrients and there should be no problem.
Peace
I don't think you need a flush, just change out the res (this is the NFT?) Changing nutes shouldn't damage the plants.
Flush it out for 24 to 48 hours. Change the water a couple of times. Then use the new nutrients.
