Barneys Farm Pineapple Chunk Leaves curling upwards!!

**Fat Sticky Nugs** · 11-22-2012, 07:56 AM

I have a Barneys Farm Pineapple Chunk whose top leaves are curling upwards towards the light. (U Shape)
I had just moved this plant and another under my 600w hps a little over a week ago. I have the light raised pretty high 1 1/2 feet above the plants. I also have a fan blowing over top of the plants also.
I have been using Fox Farms trio nutrient line to feed my plants once every 3 waterings. I also transplanted them into 5 gallon pots a little under 2 weeks ago.
My temperatures stay around 75-82 degrees for the most part.
I also switched my 600w hps to 12/12 this morning after it being on 24/0 for almost a week.
What could be causing these leaves to do this?

The plants could be responding to the heat under the bulb.......or possibly the beginning of a cal/mag deficiency.

Do you know what your humidity is dude? Also it could be the plant adjusting to the change (could). Peace

Not sure at all what the humidity is, and after seeing the curling I raised the lights about 5 inches higher and adjusted the fan to right over the tops of the plants.
And it's only 75-82 degrees in the room how could it be curling due to heat?
The pineapple chunk has looked shitty compared to the other ever since the beginning though.
Can the curling also affect flowering?

Yea, as another already mentioned, it could be the beginning of a CalMag issue. Mag Def will curl those margins up like that, along with Heat, but I guess we determined heat was not the issue.

What would be the best way of combating this CalMag issue? Dolomite Lime, epsom salts, or CalMag?
Also I forgot to mention the tap water I use runs through a water softner first which I'm pretty sure could be causing this.

Yep, if your filtering your water, you are probably pulling out the Calcium and Magnesium, so some CalMag+ will help get you back into the swing. (providing your nutes arent giving you plenty already)Also before you go adding more of anything,,, Be sure your PH is in an acceptable level.. If you simply experiencing PH Lockout, then that is an Easier fix. If you have determined by no uncertain terms that your PH is on the money, then go ahead and start adding as needed.

Is there any diy way of measuring the ph? I lost my meter about a month ago and have just been sticking to feedings every 3 waterings as reference.
Lol, I know I could be way more serious about this grow but I don't have the extra cash for a spare meter at the moment.

Curling up is almost always a heat and or humidity issue.

**Fat Sticky Nugs** · 11-22-2012, 09:52 AM

I can comfortably sit in the room and put my hands over the plants and hold them there for a couple minutes without them being hot.
I have no real way of knowing if theres a humidity issue either because I don't have a digital thermometer.
Any ways or ideas to really tell what the main cause of this is?
