Wierd Issue Or Deficiency On My Super Skunk??? Please Take A Look Guys!!

One of my Super Skunks is showing purple/black leaf tops than they die yet the bottom of the leaf is green. Other leaves on the plant have small purple spots that spread. The plants are in FFOF soil and 10 days in flowering and have not received any bloom nutes yet. The last watering they received molasses and water thats it PHed to 6.7. The time before they got a super mild watering with Pure blend pro grow. Does this look like a deficiency of some type?

Here is a few more pics.

Can you tell me the N-P-K # on your pure blend pro grow???? looks like a potassium def, not sure until you give us some more info: temps/ rh/ tap or filtered water/medium's ph.........

seems like a micro nutrient or potas. deficiency friend. i wish i could tell you more but im a little busy atm.

PBP Grow 3-2-4, Temps 73 degrees rh 62% R/O water always phed to 6.7 not sure on my fox farms ocean forest soils ph the run off was 5.9 but it comes out like that even in fresh soil never ferted I belive cuz its so fortified. I have botanicare products,cal mag grow bloom and liquid karma sweet and clearex

FFOF is a hot soil mix, good call on not adding to much shit...........need to get that RH down further into flowering/ no biggie though......personally i would give it one more watering of just RO.....If the symptoms worsen you know it's a def, hit it with 1/4 strength flower nutes(p-k)/cal-mag(ro removes all cal/mag) and go from there......good luck

Ya I learned this batch thats nearly done that the soil is finicky but it really makes them girls get sticky and stinky lol. How much cal mag do you think I need per gallon? I was gonna go with 2ml a gallon.

thats a sever phosphorus def. either ph issue of some sort but i dont think its just a phosphorus problem. but you can start there. if your run off is 5.9 but your watering 6.7 thats not right... you need a couple tablespoons of lime mixed in with your water make a milk then water well. i would say 2-3 tablespoons depending on the size of your pot, that will fix the problem adding more nutes will only make things worse, get your ph correct and that will make a massive difference all around! idk why people are saying its a micro def your using ffof its a good high quality soil only def you could get would be calcium or magnesium because your using ro water but both of those are macronutrients not micro but you said your using cal/mag.
