Wicked leaf curl. What did I do?

I’m in coco. Under 1000s. I feed daily with GH Flora until significant runoff with ph between 5.8-6.2. This is my second time running this strain and I’m pretty much doing it the same way. I did get all new bulbs. Something happened early on that stunted growth. I’m unsure what I did but this is the end of week 6. Last round these were huge tops at this point. This strain is quick. 7-8 weeks. Any idea how I managed to screw this whole round up?E089E22A-A9B4-47E1-804D-685DC2AD591B.jpeg

What are the temps running where that is happening? Could be some heat stress if it's only happening where the canopy is the hottest.

I don’t know the temp directly under the light but I have a few thermometers scattered at canopy height jut off to the side and it’s usually about 73. It’s the only strain doing it and I’ve raised the light to over 2 ft. Should I go higher you think? I almost did earlier but convinced myself it was something else.
 
Sometimes a leaf twist is caused by a micro nutrient deficiency (usually pH related), heat can cause it too. If that plant is directly under a light perhaps move it off to the side and put a shorter plant there. Are you using a calmag product? RO water? With coco you may need some cal mag even with tap water, definitely with RO water.

I’m on a well but I use cal mag everyday. .3 EC religiously. Maybe it is light. New bulbs I’m not used to.
 
Well, something had to have been changed for results to be so different. So I guess this will come down to isolating the factors of your grow, and finding which are different. What brand of bulbs are you using? Are temperatures consistent compared to the last run? If you can maintain the correct temperatures, your lights should be just fine at the distance unless you're also using some type of LED or CMH light. As far as HID goes, I too use a 1000w and don't have any issues at 1 foot away from my cool tube as long as I can maintain appropriate temps.

I’m using hortilux 1000w hps. Same base nutes. I did switch my cal mag brand for flower to a no nitrogen camg. Temps are pretty consistent but a bit warmer sometimes. Last run was negative temps outside at night sometimes. So because of that I’m able to keep my intake on all the time. I redid my room. Built new tables. Rearranged. Moved hoods. Added irrigation that I’m still not really using. I did use that for a couple weeks but stopped. I can’t think of anything else.

you are using well water, so you may want to read this article.

Questions regarding water.
How important is water quality in hydroponics?
Water containing too much calcium and magnesium (called "total Hardness") may create serious problems. Contact your municipal water supplier who can provide you with an analysis of your water supply. If you are using well water, many laboratories can provide you with an analysis if you send them a sample. If the dissolved salts in your water supply measure 200 ppm or more, we strongly recommend that you obtain a water analysis to determine calcium content. Excessive calcium is the main factor in determining if your water is hard. If an analysis of your water supply reveals that the Calcium content of your water supply is greater than 70 ppm (mg/liter) you should use Hardwater FloraMicro. Hardwater FloraMicro provides rapidly growing plants with a combination of chelated micro nutrients uniquely formulated for hardwater conditions. Other options are to collect rainwater, install a reverse osmosis filtration system, or use purified water. Do not use mineral or "spring" water, which can unbalance the nutrient solution, or even be toxic to plants.


My water is chlorinated, Is this a problem?
Chlorine is highly volatile; it evaporates as soon as it hits the air. By the time the nutrient solution reaches the roots, the chlorine is gone.


I understand the roots also need oxygen. How do they get it?
In a properly functioning hydroponic unit, the roots receive oxygen from the air, which surrounds them, as well as from the oxygen, which is dissolved in the nutrient solution. The proper medium can play an important role in this process.


What about water temperature?
Temperature of the nutrient solution should be in the range of 65 to 80 degrees Fahrenheit (18 to 26 degrees Celsius). Before adding water to your reservoir, it is a good idea to allow it to come to the same temperature as the water in the reservoir. Plants do not like rapid temperature changes, especially in the root zone. Aquarium heaters can be used to warm the nutrient solution in the winter, and look for "chillers" to cool the solution in the summer if high temperature becomes a problem.
 

I hate to try and diagnose, the leaves look water stressed. Heavily triched up leafy smaller bud - struggling to transpire enough water.

Why i thought there had or is some overdrying going on leading to not enough root water and leaf problems.

Anyway just ideas and i hope somthing works out :-)

Like not enough water? It could be I guess. They definitely get water daily but they were getting multi feedings with the irrigation. I thought they were getting too much then so I stopped with it. Maybe I’ll turn it back on and see if it fixes itself. I appreciate the help.
 
That likes like environmental issues. The leaves are praying, all facing up and your edges are curled as well. Look at light distance, heat and humidity.

I see healthy plants overall, other than the heat/light stress. They're running full speed, so it's possibly not enough water like @Kingrow1 suggested, but I would think you'd see some other signs.

You said they got stunted. Was that in veg or flower?

I've stunted plants in flower before and they took longer to finish. Hopefully, that's the case here if your not on a deadline and have a couple more weeks.

They look well fed and they are pushing to produce. Did you defoliate as heavy last time? Just trying to find the variables.

I've had plants stunt in flower as well, and when the stunting is severe enough, it can really set back your plant's progress and overall weight. It's possible that a single event stunted them severely and now they look so far behind because they pretty much are behind where they were compared to the last grow?

Yea. They’re way behind. And actually now I’m seeing signs of Hermies on most of my room so that’s awesome.
 
Lol, the irony, I was gonna say it looks like anytime I try to run GH Flora trio... then I read the first line..
BAck the fuck off on the dosages, flush as per the schedule...

High temps cause tacoing, not that weirdly twisted root burn curl.
