Locrian99s 2nd grow

[Locrian99]

Yea I’m not worried about not making it to harvest just worried I might lose some of the mass they should be putting on in the last few weeks. It’s an 8 to 10 week strain, 49 days will be Thursday. Plenty of good healthy looking leaves in her still. I did notice my AI’s are starting to get the yellowing leaves underneath that you get when they start fading. I’ll be checking the trichs on those under the scope probably Wednesday (day 51 for them) look at starting their final flush soonish. They didn’t get the sledgehammer.

Wow 4k I see. Hope you solved the problem. I'm confident you'll make it to harvest.

I was worried about lock out occurring with the 100% nutes been trying to push them a bit to see what happened but my runoff ppm had been super high. Shouldn’t be lightburn based on light distance. That particular plant run off was over 4K last I checked the ppm. Fox farms feed chart actually recommends giving sledge hammer multiple times throughout the grow, I thought I’d try it. Thinking I would’ve been fine had gave a light nute dose right after rather than waiting for the next watering. Plant looks the same after the 12 hours of lights on. Guess I’ll see what she looks like when I get home from work.

Curious as to why you decided to use a flush so early? Probably has something to do with it. Flushing releases the bond of nutes. Unless your ph/ ppm was wonky or you had some kind of lockout? I wouldn't use a flushing agent unless I'm at the end of harvest or having lockout problems.

I’m thinking when I did the sledgehammer on Sunday that it stripped all the calcium out (as intended) but I should have possibly given a little bit of nutrients right after. They were fed on Friday, I see the issue now but I’m guessing the problem wouldn’t be instant to show up or fix itself. So while I gave calmag on Friday the damage had been done already but the effects were really showing. What I’ve read different strains and even different phenos can be more sensitive to calcium def. I have two WW phenos so possibly this pheno is more sensitive and that is why it looks worse than the other. And the WW are known for wanting lots of nutes and that is why I’m not seeing it on the GSC. Hoping when they were fed Friday it’ll stop it from spreading according to nebula though it can take a week for the problem to clear up (I’m assuming stop getting worse, as the damaged leaves won’t get better).

Looks almost like they got burned. How much calmag are you giving with the 100% nutes? 2 more weeks I know feed charts back off calmag close to flush but it wouldn't hurt giving them mag with a regular watering. I had to do the same with my mother plants. But looks almost like light burn to me which can cause deficiencies as well.

I think I see it starting a little on the other Wonder Woman.

[oldjarhead100]

so its only on one plant is it the same strain?

[Locrian99]

Yea it’s the 2nd plant pictured in the pics from Friday nothing that I really see there.

[Locrian99]

Yea based on the location on the plant reading the calcium def thing on the main site I’m feeling fairly confident it’s calcium. I saw some very mild oddities if you will on the leaves which is why I did the sledgehammer in the first place but I think I would’ve noticed these last night looking like this and for sure when I watered Friday.

Those look more like Cal.
Not sure it makes a lot of sense though - your pH would have to be way off to not buffer in soil - and cause such quick symptoms. Perhaps something else is causing Cal to lock-out. The fact that it's coming on the heals of a flush is also significant I'd think.
I have spent the better part of the weekend reading about coco chemistry - I have far fewer ideas about what interferes with Cal in soil.

[Locrian99]

It could be the 100% nutes schedule finally catching up to me I suppose. Crappy timing for this to show up it’s time for bulking up! Next watering I think I’ll hit a bit higher ph probably 6.7ish and maybe add calmag even though it’s a plain watering. Pistils haven’t really started turning much on these so I haven’t even thought about checking trichs for when to start final flush.

[Locrian99]

Here are some better pics of just the leaves.

[Campesino]

I didn't think Cal when I saw the pics, but could be. "Crispy" is often a burn symptom rather than a deficiency, but I am not sure. Something is certainly out of balance!

[Locrian99]

Best I can tell is calcium deficiency. I’m using cal mag so I guess nute lock out possibly causing it from maybe the PH drifting too low. I haven’t check ed runoff on these in a bit but it was coming out right at 6.0 last I did.
