Twisting on new growth

I'm noticing some weird twisting on the new growth on my Green House Seed's Hawaiian Snow. What's interesting is this is only happening on that one plant. Every other plant is growing great and even that one is exploding pretty fast, but all of a sudden the leaves are showing signs of nute burn and heat stress. Yet growth isn't slowing down at all.

The two that are growing in the ten gallon black fabric grow bags were started the same day, are in the same potting mix, and for the past two weeks have only received rain water. They were given a very light feeding of X nutrients Grow & Micro (aprox 1/4 strength) a week ago, but 20 minutes after I fed them it rained really hard, so I'm assuming most of it washed away. Plus I really do not think it's the nutes anyway since I used the same nutes last year and didn't have this problem and it's only occurring on one plant. I also believe that if they were nute burned, this problem would have shown up 1-2 days after feeding, not a week later.

Here's some photos so you can see for yourself:



The first photo shows three plants side by side. The second photo is a close up picture showing the twisted growth on the Hawaiian Snow strain. This is the plant that's on the far left in pic #1. The third photo is Lemon Skunk and it's the one on the far right. Notice how it looks perfectly fine. Again, both plants are the same age, same overall conditions. Only difference between the two is the strain, but they're both from Green House Seeds. I have a few other strains growing elsewhere in other potting mixes, but again none of them are having this problem. It's only the H. Snow.

What's your guesses as to what's causing this? I've seen it before in other people's indoor grows, and normally I think heat stress from the lights, boron def, or nute burn. What do you all think it could be?

Average daytime temp is 80*F and ave night time temp is 60*F.

Do you PH your nutrients? Sometimes if there is a Ph fluctuation it can cause problems like that. But it seems really common. I've asked the same thing on this board. Found out it was because GO states to use with tap water I used to always PH but my meter broke. Bought the test drops and come to find out that when I mix everything the Ph is around 5 even if I let it sit. Nutrients are only available in certain ph ranges and causes odd things to happen. I would start checking Ph into and out of the plants to make sure they are kosher. Good luck. Happy Growing.

Straight up a very sensitive strain imo. Feed 1/4 strength for next 2-3 feedings and go from there.

Plants are still very small though, so some may have better developed roots than others and can absorb the nutes better/quicker/faster/more efficient then other plants. They need to grow at that stage, PERIOD.

same happened to me. twisted growth, so im flushing everything out with clean un-nuted water to see if the twisting straightens out. hopefully it does soon so i can start feeding them a super weak solution to let them adjust.

Last week when I fed it 1/4th strength nutes I did PH'd the water, but it had rained heavily right afterwards, so I think it was all flushed out anyway. I haven't needed to water since then because it's been raining every few days. Haven't bothered to PH the rain water.

And thanks everyone, I appreciate the feedback.

I emailed Green House Seeds early this morning. Who knows if they'll actually respond, but if they do I'll let you guys know. I am thinking this strain is very delicate and it's just not used to my region. Very weird though. I'm in So Cal, I always assumed you could grow anything here. Whatever it is, I'm hoping it'll clear up on it's own. If not, fuck it.

Green House Seeds replied back and as promised here is their response:

Having slept on the issue, reading my notes, and really thinking about all the possibilities. My guess is that it has to be some kind of heat stress. I know the temps have been avg 80*F, but maybe there were spikes in heat that I didn't notice or the rain plus short burst of intense sun light played a part. If it was PH or a nutrient problem the plants should be stunted. Since they are still growing at a very fast pace, heat stress is the only thing that I feel that makes any real sense.

If anyone disagrees I would love to hear your opinions.

I'm getting some more answers on Green House Seed's forums. People are suggesting nut def and PH more than heat stress. Ah, lol, the stresses and pleasures of growing. What to do what to do.

I'm going with the hippo with diarrhea. That happened to a few of my plants... damn ninja hippos

im gonna take a stab on this...i recently had some (friends) issues like this .the twisting got way worse, the coler and texture showed no ph/salt or over under fert issues...it was discovered that the heating had fryed so at night to day we were getting a 20 plus degree spread in temps....this has been relegated and the new groth is comming back to normal....maby the 20 degree temp flux?????

Thanks, I can see that happening. Even though it's outdoor so cal weather, it does flux a bit. What do you think about the color of these plants? Is it me or are they a tad on the light green side? Last year my White Rhinos were dark green. I have been over caution on the nutes since I'm not as familiar with these strains. Not sure if the green is spot on or if its to light and maybe I should just go ahead and start feeding early. I was hoping the fresh potting mix would have give me a good month before needing any additional feeding, but now I'm second guessing that.

What do you think about the possibility that it could beboron deficiency?

Look up calcium def. That can cause twisting and contorting of new growth but usually is dark green. Could happen if u use RO or distilled water or have added to much Mg.....

Or rainwater. Op said thats all his plants had the past two weeks. Rainwater is known to be soft and therefore calcium and magnesium are in low content. Also, it may be a plant disease.

Very good point ! rep to u !!!

I don't have a PH or PPM pen yet, so I went to my local garden store and bought a few PH and NPK soil test kits. PH was averaging 7.5, which I read can cause micro nutrient lock up. On top of that, when I tested NPK levels, they were all very low across the board. So high PH plus low NPK to begin with means it was definitely a deficiency. The fact they were still grew at a good pace makes me believe the plants were still able to take up the little macro nutrients that were present, but it couldn't get any micro nutrients like Ca, Mg, and Boron.

I haven't tested our local rain water for micro nutrients, but I know it's not that soft (low in Ca & Mg) because the water tends to leave white water spots on everything. I've been told this means the water is a bit on the hard side and what makes it hard is usually Ca plus small amounts of other minerals. Still the higher PH probably locked it up and make it hard for the plant to get to it.

Also, I really think a big problem (besides the high PH) was the low availability of boron in the rain water. I was reading some published papers by the University of California Agriculture & Natural Resources, which also happens to be my local cooperative extension office, and their research paper said that some areas in California the soil has been found to be very low in boron and it can affect crops like citrus, avocados, and bean crops. In other areas in California, particular areas with streams or when people use well water, the boron levels can be very high. The paper went on to suggest that if the boron is high, collecting rain water and flushing the plants will remove much of the boron. Where as watering lightly and frequently using city water would raise the boron levels.

So yeah, I just wanted to post back and let everyone know what I found out and the way I'm correcting it is by using city water, a full dose of Micro, Grow, and Amino nutrients, then PHing the water to 6.0 - 6.5. I'm just tossing the amino because I did read it can help stressed plants, and even though I'm very skeptical of those claims, I know it won't hurt my plants any.

Last thing I will add is a big THANK YOU to everyone that responded and tried to help. I also hope my mistakes will some how help other. With that, Happy Growing and I'll post back once I see that things are improving.

Thanks again!!
