What Nutrient's are you using?harvest moon organics
How much of each nutrient are you using with how much water? *Knowing the brand is very helpful*
soil nutrient- 2tsp
bioactive- 2tsp
plant growth enhancer- 2tsp
Yucca- 1Tbl
Calcium/magnesium- 1tsp
biggest blooms-2Tbl
bone meal- 2Tbl
Amino Blast- 1Tbl
Carbon Jolt- 1/2tsp
all are per gallon
How often are you feeding? when plants are dry-every2-3 days I usually water everyother time with plain water
If flowering, when did you switch over to using Bloom nutrients? I usually give plants rsome right before flower and then when they are in flower.
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect) same order as I listed
What is the TDS/EC/PPM of your nutrients used? doesnt say on label
What is the pH of the "RUN-OFF"? Not sure, will post when I water later tonight.
What method of pH test was administered? Using Strips? pH pen? I will be using the strips.
How often are you watering? every 2-3days
When was your last feeding and how often are you feeding? everyother watering with nutes
What size bulb are you using? 600watt
What is the distance to the canopy?16"-18"
What is your RH Factor? (Relative Humidity) about 35%
What is the canopy temperature? Low 70s
What is the Day/Night Temp? (Include fluctuation range) day-72-78, night-62-70
What is the current Air Flow? (cfm etc.) 747cfm
Tell us about your ventilation, intake exhaust and when its running and not running ? I currently vent through my double light setup. It runs when the lights are on(8pm-8am) There are also 3 large fans blows in the room. Lots of air movement.
Is the fan blowing directly at plants? Yes
Is the grow substrate constantly wet or moist? No
Is your water HARD or SOFT? soft
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? well water
Are you using water from a water softener? no
Has plant been recently pruned, cloned or pinched? no
Have any pest chemicals been used? If so what and when? no pest strip by the plant
Are plant's infected with pest's? no

here is a couple shots of what I mean. the plant has been flowering for about 4 weeks and has had curly leaves the whole time...its not too often I dont know whats happening so some help would be great. There is no yellowing but crazy curling all over. I also have some browning of some of the lower big fan leaves which has caused some to fall off.







here is a look at the whole room, you can see where the air is pulled through my lights.



thanks for your help!! I really appreciate it.

You're hitting them with too much N. Bone meal on it's own has enough N to get most plants through flower. If you want me to go into more detail, I'll need the N-P-K rating of all of your nutes.

You are overwatering and too much wind directly on the plants.

ps... plus your Nitrogen is fine its the "K" Potasium that is a bit to high.

thanks everyone for your help. I will adjust somethings and see if it helps.

I had quite a similar problem with mine.. the leaves looked good, but they drooped and curled. All I did was lessen the air flow onto my plants and they jumped right back up. Turns out they were just too cold. If nothing happens after you try your adjustments, you might want to try that.

Looks and sounds to me that they're over/incorrectly watered and over-fertilised, there's a lot going on there. 1 - 1.5 foot high in 5 gallon containers and you're watering every 3 days? That sounds really excessive to me and would be consistent with the state of your plants - they're constantly drooping indicating a lack of oxygen in the root zone due to water-logged soil. Canna roots do not like to sit in water logged soil.

You shouldn't re-water plants until the pot feels light again and the soil just begins to start pulling away from the sides of the pot, ideally water just before that happens - do not let the soil dry out. In your size containers and the size of your plants, your watering schedule should be nearer to every 6-7 days, not 3.

It's also difficult to understand what nutrients you're feeding and what soil amendments you're using and when your repotted. Did you repot into fresh soil before flowering or grew them from clones in those containers? Because that will affect how and when they need feeding, if you repotted prior to flowering they should only need a light feed around now, if you didn't and you're using organics, it will be hard to figure out their feeding requirements as the soil could be quite depleted of natural macro/micro-nutrients.

The essential principles of organic growing are not only to feed the plant natural and organically derived nutrients but also to allow the plant to take whatever it requires for healthy growth from soil itself. Growing in soil substrates rather than say hydroponically are one of the principle ways of achieving this - which is why so many organic growers grow in soil. There are a few nutters who try and do it in Coco or hydro, but hey good luck to them.

Our main job is to ensure the plant has sufficient nutrients in the right quantity and right type to meet the plants 'natural demands', which will change depending on the plants stage of growth. Too few nutrients will cause deficiencies, too many will cause a build of nutrients in the rhizosphere than can lead to toxic levels and growth and mould problems. With chemical based fertilisers it has the added problem of producing a high salt buildup within the rootzone which actually reverses the osmotic process the roots use to intake water and nutrients. Instead of intaking water and nutrients, the roots have it sucked out by the salinity imbalance between the root walls.

Anyway I digress. That's the problem with toking up some Satori, you tend to ramble.

Have a look at your watering technique and frequency as I beleive that's the first place you need to look and correct if necessary. Good luck.

chunkybuddha and tree&leaf thanks for the input

Yes I know they got a bit overwatered and I didnt know that the air will actually make them curl. I am fixing these problems.
Also I transplant the clones from 1 gal pots into the 5gals a few weeks before flower. Because I am keeping my plants small I am actually dropping down to 3 gal grow bags...a much better fit for the size I want.
The soil I transplant the plants into before flower doesnt have much nutrient additives in it. This way I can use nutes right away and not worry about too much feeding.

I agree though and I am going to be paying much more attention to the amount that I feed and water.

Thanks for all your help.
I will keep you all updated.

I found it on some guy's blog before I was a member here. I didn't know he was that popular.
