Curling tips

My plans have some leaves that are curling under at the tips, also the edges on some are rolle up also. The leaves look sort of wrinkly almost. I wather 3 times a day in hydroton, ppm 390, ph 6.0 air 78 degrees or around. running 3 1000w lights. Pleeease help. Am I over watering? or to less

come one someone please anything?

this is lame. i have just abouth te same problem. only read my thread. ive taken exactly the opposing actions as you. what size is your con tainer? mine started to curl down and uickly found that my soil was to wet. i have it in a 5 gal bucket. i transplanted it, watered it , then feed it the next night. after morning of feed the curling was worse. so ive been told to let the soil run pretty much completely dry and to water it real well when you start to see that its dying or when the soil is dry.
so yes
1 of many things ive found.
1. soil is to moist, roots not getting enough air(leaf tips down)
2. too many nutrients.(soil has nutes) ive been told to alternate water feed water feed by the day.
3. rhs too low and or heat stress (leaf edges flipping up)

Please post pics when asking for help. It will allow us to give more accurate advice. Based on ur description... U may have a little heat issues. Specially with 3 1000 watt lights on your girl. How far are your lights and How long are u watering for?

I will put pics up as soon as I can figure out how to or tonight when my roomate gets home. I am usuing the hand technique but the light are about a foot above the plants. Im in hydroton ( bucket system, watering is on a timer, goes for 15 min. Is that to long? I have about 19 plans, It takes prob 5 min to fill. Also am on 18-6 schedule.

I havent seen your thread but Im not in soil, im using hydroton or clay balls, with the flood and drain buckets. Im not sure what it is

here are the pics of what they look like please help me.

My long-shot take on this is not overwatering, but a closely-related complaint: roots suffocating. An airstone in each bucket should help if this is correct. cn

<add> Do you aerate your nutrient solution?

I have to 12" air stones in my resevoir which holds 30 gallons, Do you think they are in water to long? Its on a timer, 15 min, but it takes about 5 to fill. I actually picked up one bucket and the roots were already thru the bottom of it. Should I lowere the water level where the fill line is at?

and what is root suffocating? like its in water to long?

Wish I could give you a confident answer. I'm guessing for some reason that your roots want more oxygen than they're getting. A cheap(?), easy diagnosis is to tweak your res with hydrogen peroxide, say 125 ml of 30% for your thirty gallons of solution. (is 30 gallons the amount of soln, or is it the res' max capacity? Adjust accordingly up to 5 ml/gallon of actual.)
Otherwise I'd look into a way to get a bit of fresh air into those buckets.

But no; i do not think that being under aerated water for 15 minutes should be the problem. DWC keeps the roots immersed, but compensates with aggressive aeration in each bucket. cn

<edit> How high do the buckets fill? Is there an overflow provision? Is nute soln actively overflowing/circulating during those 15 minutes? Do the buckets drain completely? If not, how deep is the residual?

No that isnt the max for the resevoir i could put in another 10 gallons prob, and I had h2o2 in there about a week ago. I put in 90mg and a quarter strenght nutrients. they were doing great. Did the h2o2 dissolve or something? The buckets do drain all the way, when they fill the water just sits in there. and then drains. I picke a bucket up today and the roots were already coming thru the holes in the bottom of the bucket. I have the fill line about 10" up should I lower it? and i dont know what a overflow provision is. or what overflowing or circulating during the 15 min means. Its a system I bought from the store, with the brain (timer) and then it fills the buckets and drains them. This is my first grow.

and how do I get fresh air into buckets? Its not the lighting right? Or over watering? I water them 3 times a day and im in clay pellets

Hydrogen peroxide lasts at most a day or to... the micros 9esp. iron, manganese) in your solution will decompose it. That's how it oxygenates.
However I do think an airr stone in each bucket might help a lot. If air is a limiting factor, and your peroxide experience suggests that maybe it is. Maybe. cn

ok thanks, I just put in the h2o2 and ill see how it does. I dont have any room to put an air stone in each bucket. they have a bucket then a bucket that fits into that with holes in the bottom to flood n drain. So all I can do is have them in the resevoir. Ill hit you up tomorrow and tell you if the look any better, Thanks alot though for the advice

The h2o2 didnt work, things look the same??

Increase the ppm to 600 - 700 and add air stones in each bucket.

I sent a message but I got an error message back. Rollitup is messin up these days.

Hold it, aerate? meaning squeze some air out of your bottle turn it up side down and let the air boubles pass back through and through again? will this help stablize the ph or what is the purpose?

Roots need oxygen for cellular respiration, if your water is anoxic, they could rot and die, killing your plant. You only need to aerate your water for hydro, not soil. You can overwater in soil tho, and this would suffocate your roots.

Finished nutrient solution, not the concentrate in the bottles. I presume that to be stable.

rocky, I share your frustration. I've had a hydro grow in which *nothing* went right. i ended up rescuing to soil. But I had another in which *nothing* went wrong. It's irritating to not be able to diagnose a problem quickly. I can suggest aerating your buckets, but I have to admit that i don't know the certain cause of your plants' poor health. I can only suggest possibilities. cn
