Coco advice needed!

[Munkey]

Hey fellow growers,

Im on my first coco grow and so far so good til a couple days ago. I’m runnin 2 auto six shooters. Same nutes (canna a+b, hygrazyme, cal-mag), same environment (viper spectra 600w, 3x3x6 tent, coco, 5gal pots). Girls are about 5 weeks old. The one on the right has some weird spots on a couple of the leaves . Sorry for the shitty pics, I’m not a photgrapher. Any input would be greatly appreciated. Thanks everyone!

Hey munkey - plants look great - flower stretch is about to happen - are you giving full strength on the cal-mag?

[Munkey]

Thanks Canuck147. Yes I’m going full strength on cal-mag. Both plants are getting the same everything. Kind of weird one plant has a couple funky leaves and the other one is fine....🤔

Hi Munkey, what's your ph? Are you checking and adjusting ph after adding all nutes and supplements? In coco, 5.7 to 6.1 is a good range, IMO.

[Munkey]

Hey Sheesh,

Thank you for your feedback. Yes, I keep my ph at 6 on the dot.

[Iammygod]

How much and how aften do you water the plants?

[Munkey]

Hi lammygod. I took Nebulas advice and water to runoff and then water again when the top of the pot starts to dry out.

Ph and calmag r taken care of. It looks to b on oldest leaf in pics. Phosphorus deficiency ? Check ph runoff on her b4 changing feed

[Munkey]

Hi Speedy, I’m at a loss. It’s gotten worse. It’s developing on the older leaves. New growth is fine. Up to now The feeding/watering for both plants has been the same. The other plant is perfect which is what has me stumped. I can’t find anything anywhere on these symptoms.

[Speedygreen]

I had a similar problem with a strain I built. It was a soil grow. My last option was to transplant into a larger pot. That cleared up the problem with that plant. Turns out cops tend to notice 6ft wide plants from the air.

[Mr.furley]

Calcium and magnesium need each other to absorb, in coco and hydro this is best done between 6.2 to 6.3 PH.
I would suggest flushing your plant with 6.3 water the next feeding remove your nitrogen but double up on your PK , the next water only with calmag ph'ed at 6.3. And resume your feeding schedule after that.
do you mix B then A in that order?

[Mr.furley]

Do you just feed, feed, feed,....
OR feed, feed, plain water...
OR feed, water, feeding, water....

[Munkey]

I have been feed, let dry, feed, let dry, feed, let dry (not completely dry, just the first inch or so)

[Mr.furley]

then I would suggest 4x the pot capacity plain ph, calmag water., after your pot drys move your watering to a Feed, feed water,with 2 gallons PH'ED only and repeat.

You plants look great - just keep an eye on that patch, see if it changes or spreads. I wouldn’t worry otherwise.

[Munkey]

Thank you whitebeard!

I have seen that a lot growing in coco/perlite mixes and from the Hydro PH charts I dont see a "perfect or nominal" PH level so I let my PH float between 5.8 and 6.3 and once or twice a week I add a tsp of Epsom salt along with cal/mag. I have been doing that for a few grows and the problem seems to have gone away

[Munkey]

Thank you Allenpro. This is my first coco grow and I’m too close to bring these home to quit now....lol. That sounds like sage advice.
