A synthetic crystallic fert? Do you mean a water soluble granular synthetic? At any rate, you shouldn't have to wait three weeks to see results. When I see mine getting a little 'down' I give 'em a good dose of petro chem 20 20 20 and it perks them right up in just a few days. In a week's time, the color should be about back to normal except for the leaves that have gone too far to the 'other' side.i recently started givin her a synthetic crystalllic fertilizer or something like that, that has N,Mn,Mg,iron....its the first time i feed them in 4-5 weeks,and the agronomist told me it ll take three weeks to see results so i'm waiting.......
I'm American just like you dude, but lets be real, the rest of the world uses Celsius, so just because you're too lazy to glance at your themometer in your grow room to see what it converts to, doesn't mean you can demand conformity from a person posting, just plain rude.
I didn't mean to sound mean,sometimes dialog can be made to look rude. What i'm saying is the most common unit for temperature is in farenheit,I just like to make it easy for people to understand,didn't mean to sound ordering. Hope you fix your problem,goodluck. Oregon The Chronic State.
Not sure what your thinking,but a nitrogen deficiency is more common in bud then in veg.
