Why are my leaves twisting???

keyunit

hello peeps, ive started to notice the leaves twisting on a couple of my plants they are about a 9 days old under 400 hps. i think i read somewhere that this was due to over nuteing but i cant be sure, can someone confirm this and possibly supply a solution. i gave them bio bizz grow half strength the last two waterings, im now thinking that was a bit much. my soil is TERRA and the NPK is 12/14/24 if that helps(girl in shop said it was good). thx guys

@ 9 days old it should only be getting ph'd water and maybe a drop of super thrive. How far is your light?

Twisting leaves is one of the symptoms of too much heat. What are the temps in your grow area? Nute burns usually manifest themselves with discoloration and/or leaf curling under.

The sound of things both nutr and heat problems.Watering your plant go's something like this,pick up the poted plant and feel the weight of the pot and plant.Now water with nutr at 1/4 what the bottle says.After watering pick up the pot and feel how much the pot weights after watering. Water till you see water trickle out the bottom of the pot.Let it dry out,you pick up the pot and feel the weight,when it drys it is lighter and time to water.Watering go's like this water&nutr,let dry,plain water and let dry,plain water let dry,3rd time water&nutr and repeat above. Heat 400watts is strong light on baby,rise the light some till they get alittle bigger. PEACE

the temp is 27 in shade and 28 in the light, my light is 60 cm from plants. the temps have been a bit lower since i added an new intake but seem a bit high now(maybe its the time of day)

keyunit

UPDATE: i moved my light another 10 cm so now its 70cm above plants. do u think i need more or is this sufficient? im gonna try "listening" to my plants just not sure how long to wait for a reaction.thx u lot a really helpful, highly recommended site!

i didnt think ph'd water was necessary for a soil grow, i use bottled water. also if ph is needed is there a cheap way to work it? ive heard ph meters aint cheap!

green_nobody

wrong, you can get meters for as little as $20 - even big names as Hanna, a Milwaukee will start around $30. don't shop for those at hydro stores but places that sell lab stuff or look at ebay for a seller that have em on "BuyItNow" >> hanna tester, Tools, Gardening Plants items on eBay.com

and don't forget to buy some calibration/buffer solution for calibration along with it! with 40 bucks you can cover all material for the next 3 years - and you are more accurate then with paper strips or drip kits besides that a meter is cheaper on the long run anyway. Oh, and don't buy buffer in packs but always in bottles, you safe a lot that way too.

and no fertilizer for the first 2 to 4 weeks for plants that grow on soil. young plant are more then well feed by normal peat soil - fertilizer will do only harm at this point!
