Leaf curl- burn or deficiency- need help

so this is going to be a little timeline for you guys

-we had no ppm meter and our plants were showing signs of deficiency so i fed them the full dose of a bloom week 4-5 of the oneness program from humboldt nutrients (4 ml of oneness 2 ml of ginourmous). there was no buildup of nutes because we just kept tansplanting to bigger pots through the veg cycle and one last transplant before flowering.

-this dose of nutrients was the only one we ever fed them due to the transplanting. We assumed that the fresh soil would have enough nutes in it as is and that we wouldn't need to supplement it.

-almost immediately afterwards the serrated edges of the leaves were standing straight up. i have read that this may be due to the plant trying to dispell as much water as possible but is unable to due to salt build up, or low ph.

-i went out a bought digital ph and ppm meters of decent quality. i tested the ph of the runoff of the soil and it was a flat 7. i then tested the ppm of the runoff and it ran at around 560. so i began thinking it was toxic salt build up and flushed the two that were hurting the worst.

-i have been using r/o water for sometime now but due to my tank size (2 gallons) it takes FOREVER to get 15 gallons. so when i got my ppm meter i tested the tap. i ranked 120 ppm so i investigated. i believe i read that 170 ppm was okay so i figured that it would be fine to use it to flush (if im wrong PLEASE let me know)

-the gals are in 5 gallon pots so i watered the one with the worst curl with 17 gallons of water and the second with 15.

end timeline

So right now;

The yellowing and the drying/dying or browning has been the consistent signs of our problem(deficiency?), which is what we tried to fix with the nutes. Though is coupled with the raised ridges I mentioned before, which only occurred after we fed them. Therein lies the conundrum; did we need to feed our soil? Do we still need to? Do we have a salt build-up, a lock-out causing a deficiency(yellowing turning to browning and dying)? Will our flushing it fix the problem?

It's couple of days after watering and i don't believe i see more drying, but i cant be sure. and what really concerns me is that the ridges havent eased down at all and the leaves havent uncurled.



NOTE: Don't mind the black specs they are not bugs =)

so if you have any ideas or can tell me if the plant just hasnt had enough time to respond to the flushing, if you think the yellowing and browning is burn or deficiency...or anything helpful at all, i would really appreciate it.:bigjoint:

how old is your plant ? if u transplanted into fresh soil the ppm should be fine seing as u havnt put any nutes into it yet yeah ?

6-7 weeks into flowering. We transplanted it before flowering it, but had since used up the food in the soil, so as I said above we gave it a single dose of nutrients, and after the ridges were standing up.

i fed them...they curled and then i flushed them. i still havent given them any nutes since. should i give them nutes now (the ppm is currently 160)? should the curling be going down?

It does look like your plant is lacking nutes. I c theses sugns on mine when they r close to harvest. What exactly r your nutes and how often r u feeding. How often r they drinking there water
