what i meant was could i be using a more efficiant nutes with better n-p-k that would result in better growth than the pro grow that am using.im going to the hydro store and im just wondering if i should switch it up. When i raise the ppms during vegging at about 1 month into it. from 400-500 to 500-800 i get a blotche rust like color formed on the leaves,not on both sides just the top.Then the bottom fan leaves start turning a pale yellow.When i lower the ppms it seems that it takes about 2 days,but the leaves start rejuvinating.So its been 2 months and im still using the amount of nutrients it says for the start of vegging as opposed to increasing the strength for medium and strong veg growth.
