yeah sounds and looks like it. even though fox farm says its organic, if it's not OMRI certified (and i doubt highly it is) there are chems mixed into fox farm and chems are STRONG. I just recently went through this with my Age Old Organics. The only mention of organic is in the name brand, they actually make no claims to how organic they actually are when i got to looking around, and then found out they even mix chems into their nutrients. So it's best do deal with OMRI products. Now I'm not saying all things OMRI are omitted from the suspicion list of how "organic" they really are, because OMRI is just a standard met to get the approval from the company. Now I will say that at the very LEAST, OMRI seal is complying to some sort of standard which is a great thing. and when you see something going on, it's better to just give plain water and spend some time diagnosing rather than just "eh, i'll give it some nutes and see what happens". Now it's too late, and you've got stressed plants which lead to less than desirable products unfortunately. It's always better to use less than what the bottle calls for, I usually start with 1/2 recommended strength until i get familiar with the product and the strain. What you need to do is flush the pot with 3x the amount of water to soil ratio. so if your pots are 2 gal, put 6 gallon of fresh water through them and let the RUN like crazy. Then when you resume nutrient usage, start with 1/4-1/2 strength.
