Help please. What's happening

[kiwipaulie]

Ok so I'm two weeks into 12 / 12, I was feeding basically at ec 1.8 which includes the water ec of 0.25. I kept ph at 6.2 during veg. But experimented over last two weeks from 5.8-6.2. Could this be causing issues.

I'm doing hempy

Hello mate, You over feeding your plants. What's your medium, coco coir? In any case, you need to flush with only pH'ed water and your next scheduled watering, start with 1/4 recommended amount of nutrients, and slowly increase it to 1/2. Bad idea to use chemical nutrients at full recommended dose.

Feed - water - feed - water -etc.
or
1/2 strength

Add a Ca/Mg too!!!!!!

Cool I thought I may of had mites, but i couldn't actually see anything on the underside of the leaves. Will flush tonight.

So strange they were loving the full hit of nutes up into flower. Must be more picky in flower

If you're doing coco I wouldn't flush with plain water. Try 1/4 or 1/8 strength for you're flush. Coco will react negatively to being flushed with plain water and will cause more issues.

Hey guys I'm using a 3:1 perlite / verm. So you think a good flush with straight ph water.

Yeah. It's just coco needs some salts or else shit goes whack. You'll be straight in verm and perlite with water.

There's no reason to flush coco in the conventional sense. Just stop feeding it as much. Your nute burn isn't that severe, it'll go away after a few 1/4 and 1/2 strength waterings. You also can use a lower ppm with coco since it's getting topped up so much more than soil, something to consider. I just finished four plants in straight coco and never went above 800ppm even in late flower using tap water with a base of 150ppm.

Yes but how tall did they get? Six or foot plants or higher can definatly chomp up over 800 ppm easily.

Tallest is about 40 inches; the other's aren't much smaller. It's also AK Auto so being mainly sativa it's a very light feeder.

I'm not using coco, I was feeding them at 1300 ppm in veg and no issues. These plants vegged for over 8 weeks

I agree, 800ppm is nothing

My mistake, I thought hempy was coco.

800ppm is far from nothing lol. They were sativa-dominant autoflowers. They'd probably have burned severely with anything above 1200 .

Hey its my good friend Kiwi
Whats up bro?
See you have some nute burn lol
Sounds like me my 2nd crop.
Check it.. never hit the 1.8 man that shit is scary lol.
1.6 is the highest I go onless im in week 5-7 and even then i rarely pass 1.6
I would flush and check the ppm of your runoff... If you get any.
Those burns on the tips of the leaves will not go away, but its no biggie.
Hope this helped

Hey bro, is that 1.6 including your water ec?

Either way, I gave them a good flush last night, so hopefully will be back on track soon. It's strange, when they were in soil I was hitting them hard. Must be more fussy in the hydro
