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?
 
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.
 
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
 
Hi lammygod. I took Nebulas advice and water to runoff and then water again when the top of the pot starts to dry out.
 
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.
 
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.
 
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?
 
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
 
Thank you Mr. furley.....how much Water should I flush with? So far I’ve run 2 gallons of PhD water thru each of the 5 gal pots for the flush. I’ve never paid attention to the nute order......I’m thinking ph problem.
 
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.
 
I'm thinking a couple of things, 1 is your spots from the pictures look like it is around places that leaf is touching or has, spoting and discoloration can occur when leaf lays on leaf. I would remove a couple leafs.

2. It is important to mix nutes in order as to not have a reaction that can burn off nutes.

SI potassium silica
CAL MAG
Potassium and phosphorus base
Nitrogen
Microbes
PH adjuster
I do not use A+B, but my understanding is to achieve the mix above you have to mix B then a.

I would move your input ph to 6.3., calcium and magnesium work better above 6.2
 
I have been feed, let dry, feed, let dry, feed, let dry (not completely dry, just the first inch or so)
