Leaves curling upwards ???

[Coloradodreaming]

2nd week of flower and plants not looking as healthy as I would like. The leaves are curling upwards ???? Not sure if I'm watering too much or a deficiency of some sort ? Using Flora Nova Bloom, Cal Mag, Silica , Liquid KoolBloom , Diamond Nectar. Water 3x a day and temp is a high of 76° lights on and low of 63° lights off. Any feed back would be great thanks !

Stems look like they could use a little more CalMag.

You're watering 3 times per day in soil? You really only need to water once every other day if you water correctly. (Root mass and container size play a role to. Root bound and they'll probably drink much faster.)

What is your Humidity? and your PH?

 

[Coloradodreaming]

I'm in coco. Humidity around 53% PH 5.8-6.1

Also using 2 gallon pots

They look fine......probably a bit too much moisture. Cut down to either 2 waters a day or keep at three and put 25% less water in the pots.

wet feet they don't like.

Raise your temps to 85 and they will perk up. Especially if your soil is wet. Wet and cold they cry. They look fine though and your temps are acceptable.

Ok thank you sir !!!

Looking overwatered. The curled down ribbed leaves show it. Try letting the pots dry out.

I like to water when the pots are alarmingly light and show dry on a moisture meter 3/4 the way down the pot in potting soil.

 

[Coloradodreaming]

Ok thanks. I turned watering system off and going to let them dry out some

I should have asked what soil mix they are in. And what ec are you feeding at.

I know many have excellent results with auto drippers but I hand water and don’t know how to advise on regular intervals. But I assume the soil should dry just moist.

I'm growing in coco. I ran 1/2 " flexible tubing along my tables and spaghetti tubing to each plant . I have the pumps on timers and was feeding 3× a day lights on for 30 seconds. I shut the pumps off for now and put some heat on them. I'm going let them dry up and go back to once a day and see how that works

I've never really checked EC or PPMs, but think I should start. I'm religious about PH and try to keep it between 5.8and 6.1

 

[MichiganMedGrower]

You really should give that information up front. Coco is different than potting soil. Many here Grow the way you are set up. Maybe edit the original post with the needed info you just put down.

I have no personal experience with this method but I think is more likely an ec/ppm adjustment or timing or both.

In potting mix during the veg cycle you don't like more moisture for the roots? Which means more food and water but with warmer temps like 85 degrees to speed up metabolism for faster growth. Of course with proper c02, ventilation and circulation.

For this situation I am wrong with my answer as this Grow is an auto drip coco grow.

Because my rooms run every day with all different stage plants staggered I keep everything around 76 degrees and 50% humidity as a compromise.

For potting soil I grow the way my favorite breeder showed me. With a good dry cycle. I transplant up through veg when the pots are very light at 3 days. Which tends to give me a 2-3 day cycle in peak bloom. They always seem happiest when mostly dry.

The reason is in veg the extra dry time causes roots to search out and fill the whole pot looking for water and nutrients.

I can pull a 2 week old seedling out of its plastic cup by its little stem and the whole root ball will come right out. Ever since I had this extra patience my yield has doubled in the same pots and potency is much higher. I always ripen to a true finish also. 10-12 weeks for hybrids.

Yes during the flowering cycle I like the drier medium which coincides with Afghanistan, Californian and southeast USA low humidity and arid conditions during late fall. But in hot humid July I have seen plants watered everyday grow 1 inch per day with the leaves almost pointing straight up just loving it.

Makes sense. That’s why I like the stable indoor environment. And a hybrid nutrient Grow with nutrient rich soil and a bottled nute. Mostly organic now but I think a salt based fertilizer may work better for reaction time. Needs are easily met with the soil base through veg. They are naturally grown with deep well water right through stretch. Transplanted up with more fresh soil of course for the fullest rootball.

I get 1-2” growth pretty much every day in all stages. Took a lot of practice but even freshly transplanted I see new growth within hours.

Like with most things timing is everything.

I like how you describe the regional environment and how the conditions affect the plants. I am basically doing the same thing. But I look at it all the same as when I kept fishtanks. Offer a hospitable environment and let the life inside bloom. After some time as an enthusiast I can see their needs and responses more clearly.

wet feet they don't like.

Hydroponics? Wet roots is not a problem if roots are still getting oxygen, which is the real problem being exhibited. So I think the answer depends on the medium. If soil, more aeration needed in the mix. If hydro, could be root rot or solution not holding O2.

What are your ppms!!!!!!!
You're working blind. Especially in coir.
I run 100% coir. I hand water/feed once in the morning, and once in the afternoon, a few hours before lights out. Oxygen should not be a problem at all.
I feed or water, until 15-20% runoff.
I'm currently feeding 900 ppm of nutrient. Mine's a 5.3.9. Third week of bloom.
900 ppm, works out about 24mL per 9L of my water. I use tap water, less than 200ppm. I don't get a read with my truncheon.
Problem with coir is, you don't know how much it's leeching, without a ppm meter.
It could be leeching sodium or potassium, and you have no idea.
Salt will make a plant look extra thirsty. Even when the coir is saturated. It will also wilt like you have rot. Leaf tips will do all sorts of crazy too.


Does your plant feel dry? Kind of like sandpaper?
