1st week of flower, deficiency, what one?

So, what's the NPK and micro values? Labels mean nothing to me, only the elemental analysis. You need to get a handle on plant nutrition, for example........



What was that for? Did you have a chlorosis problem on the lower leaves? Can't tell based on photos under HPS. You must take the photos using a natural white balance setting.

Now, what you've done is thrown everything at the wall hoping something sticks. By giving the plant something it doesn't require, you cause more harm than good. For instance, too much Mg induces a deficiency of Ca and K. Bookmark this link - http://www.totalgro.com/concepts.htm

I'm surprised you have any leaves left at all based on the extreme amount of epsom salts applied and the fact that you have deprived them of much needed N. Haven't seen a cannabis specific nute that didn't have a deficiency of N. One reason I won't touch them.

Good luck,

Thanks for the help dude!

I'm using Plant Magics rage of A+B, it has 3.9% N, 2.5% P, 3.8% K, not sure how to turn this into ratios.. Micro values on the Calmg are 2.5% N, 0.11% P, 0.33% K, 4.56% Cal, 2.5% Mg, Fe 0.0424%, 0.0011% Molybdenuim, 0.0073% Zn.

The reason for Epsom salts was I thought I had a Sulfur deficiency, after just feeding I decided to apply foliar but turns out Sulfur effects the lower leaves.. right? Now the banding, rosetting and bright all yellow new growth must be Zinc, so I flushed them yesterday to input level with a Trace Element mix containing 0.3% Zinc.

I though N deficiency was lower leaves not the new growth?

The strange thing is, is that the leaves that are coming from the new branches are green, only the growth from the main stem has yellowing... This happened in veg as well but sorted it's self out. She's a bit retarded too, has leaves growing on leaves and has a couple of branches coming from the actual leaf itself lol. So I think it's a mixture of things to be honest, only 1 bean from 5 sprouted and didn't die, thank god she's female eh lol

Cheers for the help, much appreciated! :)

The NPK sounds fairly well balanced to me. Probably needs more N if "retarded" or stunted. Micros aren't mobile and will show a deficiency in the newest leaves. If they're NOT chlorotic then it's not a micro problem. If older leaves are yellowing, then you've got a N deficiency. A plant will sacrifice N from the entire plant's resources to provide for the new growth. I often use a high N 18-4-9 and have great results.
 
The retarded growth is genetic mate, had wrinkled up second set of leaves and now they're appearing on the leaves. I'll post up a pic, looks quite funny lol. Well must be Micro, as only the newest growth is yellow. Thanks for the help man, much obliged.
