Man....I sure could use some help. I've been all over the web trying to find out whats wrong with my plants. In a nutshell, the leaves are curling down. (See pics)

As is often the case, the symptoms could be indicative of a variety of problems(I've seen lack of nitrogen, light too hot, dry conditions, etc.:-?)-but I'm hoping someone out there in weed world will have the solution after seeing my pics.

A little background---growing 3 strains: 2 Dutch Passion feminized, Strawberry cough and White Widow AND 1 Pukka Bubblegum feminized. The White widow is primarily Indica and is not pictured, as it's doing fairly well. The Straw and Bubblegum are pictured as they're not. The Straw id primarily Sativa, and the Gum is 50/50.

Op is a DWC, started flowering the last week of December. Running a humidifier to add extra humidity (obviously), and a fan is trained on the light to keep it cool. Not sure if it's relevant, but also using a ozone generator to cover the smell.

The pictures (first 2 are gum, last straw) are a bit unclear, but they show a sickly strawberry with drooping and curling leaves, and a bubblegum with the top leaves curling--almost to the point where they are closed like a reverse venus flytrap. Surely, this is symptomatic of some deficiency or environmental effect?

Any help, general observations would be appreciated!:cry:

Although I'm kind of new, I had just that happen last month. for me it was over-fertilizing and too much water. I flushed my plants with just water for the next 2x and let them dry out for 4 days then resumed watering. the leaves starting to snap back up after they were 'cleaned' of fert. they finally uncurled when the 1 day after soil was finally dry. Hope this helps, or if anyone more experienced (I'm still waiting for my very first harvest) can help...

Thanks for the response. DWC means 'Deep Water Culture' meaning the roots are immersed in water with a bubbler to provide oxygen. I've done it before, with great results, albeit on a much smaller scale. (sorry, I didn't make DWC that clear before). So, reducing the watering is not much of an option.

I suppose it could be over-fertilizing, however. I thought it might be that, as well, but as they are 5 gallon buckets, I've been loathe to drain them all-together, instead trying to dilute the mix by adding more and more water and not adding fert for several weeks. I can't imagine that that would be the problem as they are 5 gallon buckets, and I try to err on the side of caution, especially with fertilizer, following the old adage that less is more. However, that's definitely a possibility I suppose. Don't you usually get signs of leaf burn with over-fertilization? There's none of that.

I don't have a PH meter, and I'm starting to suspect I REALLY need one. If anyone can recommend a good one.....(?)

PLEASE...keep the replies coming. (Trying to 'pool the collective':mrgreen:)

You definitely need a pH meter. Attempting to grow without one is fool-hardy. Here's a link to a cheap one...The Skunk House - The top 100 strains from across the globe.

You should also buy an ec meter.

For now empty the res, and replace with a very weak feed solution. Are they still in veg?

Thanks for the link xbravoz. AND the advice skunkushybridhttps://www.rollitup.org/../members/skunkushybrid.html (BTW, they're in bloom)......
From what I saw and read from you guys, over-fert seems a likely culprit. Growing w/o a PH meter is akin to getting into a gun-fight with a knife, so I ordered one today....live and learn.

If anything else comes to mind out there, please advise, in the meantime, I'll follow your advice skunkushybrid.......much appreciated!https://www.rollitup.org/../members/skunkushybrid.html

I've ordered a pH / ECC meter on e-bay....otherwise, I'd tell you what the pH was.....

Got plenty of bubblers, so O2 shouldn't be a problem and if anything the water is WAY to cold.......what kind of problems would that cause?

All the problems you are seeing...

The ideal temp for your res' is 67f.
