I just got my fertilizer and its a blue coloured salt-like substance, i was told to mix it with water in a perticular dosage and feed the plants....

Can i use this for Vegetative growth?.. My plant seems to be undergoing a Nitrogen deficiency.. :|

Will this cause Nute burns? ... help :D

That will work for a all around nute but it might be a little strong and burn them. Start off with half strength and move up, maybe even quarter

how old are your plants what do you base the idea you have a dif. on is that mg if you read almost every one on riu would say start at 1/4 strength and avoid mg ferts you haven't even provided a photo. noone can give you any advice with what youve given so far

I used that 20-20-20 for years..... Use only 5ml per gallon max... I nuted once a week.. that is a strong nute and you don't want to use much.. I've changed to Canna 3-1-3 so you see the diff. but like I said I used it for years with great results, just use sparingly... I also used 10-52-10 for flower.. Luck
