Here is a couple pics of some of my plants, a few leaves on each plant are starting to turn brown and curl up, I was thinking maybe a magnesium deficiency?? Its been happening for 2 weeks now and gradually getting worse, starting to worry. Anyone else having any guesses on what it is?? I am using the GH flora series , with some grotek monster bloom which I started around week 2 of flower.IMG-20130831-00678.jpgIMG-20130831-00677.jpgIMG-20130831-00676.jpg

Monster Bloom is the problem! You have P&K toxicity. M-Bloom is what 0-50-30? WAY to high a P&K ratio, way to early!
Wash,,dry out to watering point and just run the bloom formula flora and don't add any more M-B till LAST two weeks of flower......(the girls will finish and don't feel bad as this seems to be the most common problem around here).
The high P&K "fool" the plant into thinking it's very close to the "end" of it's life cycle. It then "stops"(or is Blocked from) N uptake resulting what you see your plant doing - feeding off themselves for the stored N in the plant.

Good Luck

Thank you for the help, I've given the m-b twice, first time was on week 3, and I gave a half dose, and then again on week 4 a 3/4 dose, your correct it is 0-50-30. I just gave them each 3 litres of ro water, ill let them dry out and then have them back on my schedule without the m-b. Thanks for the help again!
