    Hey guys I've got this girl that just went into 12/12 a week ago and I've got a few of these leaves that look like the pic below it seems to be some sort of phosphorus issue I think I could be wrong that's why I'm here!

    Also what's my best means of action I have tons of amendments on hand, can make teas or w.e. I'm 100% organic ROLS.
    My feedings are basically top dressings and compost teas. I also just top dressed recently before the switch to 12/12 with grokashi and incect frass idk if that could be an issue or not! CM180415-232754003.jpg CM180415-232745002.jpg CM180415-232738001.jpg

    IF U NEED MORE PICS TO HELP JUST LET KNOW DON'T WANNA HAVE TO SHUT OFF THE HPS IF THERE IS NO NEED!

    I'm gonna have to agree... phos def. I'd say your best course of action is fish hydrolysate. immediate delivery. and if you have fishbone meal or some sort of finely ground amendment with P in it, you can topdress that but as you know, it will take at a week or so before any of it becomes bioavailable. the problem with making nutrient teas, is very little of it is actually soluble in most amendments, so if you do make a tea, make sure that there is soluble P in your amendment.

    Worth a shot, coupled with a topdressing of some kind of P K amendments for flower. If you have small to medium plants I would shoot for 4-6Tbsp of topdress. Up to 8 for larger plants
