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)

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!

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!

this one sounds really noobish, but by fertilizer do you mean the bio bizz grow solution? i have a couple of pics just not clued up on the uploading of them! tell me how and i will (wow,i feel like a proper noob!):thanks:

yeah... all you want is plain water for a while...

Basically the soil has enough trace nutrients in it for the starting plant, the added nutes just help the grow swell and shoot off as the plant gets bigger and needs more than the soil can provide

some pics of the leaves twisting for ya

so far there is nothing serous to see - i can't tell what color the leaves have do to the HPS and you shooting without a flash - but besides that you seem to be lucky still, no visible burns to see in those pics.

from now one feed em water you just pH to 6.5 and no fertilizers for the next 2 weeks and this should be fine.

besides, i would veg with less power - a few tubes or CFLs will do the job just fine and use less hydro money up. also are normal HPS bulbs in the wrong side of light spec/color temp to veg with - you need more blue light then red as it holds more energy which your plants need right now. get a few 6500K/cool light CFLs or a set of tubes, doesn't cost much but safe some hassle you can have with vegging under a HPS.

Just watch that you keep those close to the light if you switch to floro tubes/CFLs - 2 inches are a good distance but it shouldn't be much more or they start to stretch, min is about an inch. and watch out because CFLs get hotter then tubes - don't let a plant touch a CFL bulb!

is that the kind of light u mean m8? sorry i forgot to say i did have them under this light in very small biodegradable pots with slits down the sides, anways i could see the root/s after 3 days so i re pottted. some with the pots still on some with out(experimenting) the light is osram 18w/765 cool daylight. i also put them under hps coz wasnt sure if that was good enough bulb. when i did go to buy one i asked for a t5 cfl energy saving bulb and they wanted to know what for!! :/ so i went else where and picked one on my own(sort of). thx

that the stuff i been talking about - check with the manufacturer's web site which color that on has but is should be good and holds far less stress potential then a HPS. should be in the range you need (6500K)

do you got a reflector for that one? could be helpful to yield the full output of those tubes.

yep i think its 6500 from what i can google, is the grow any slower under cfl? might be moving house in about 2 and half months so dont really have extra time. if its the same then thats a nice cash saver!!

not really as you then in the right spec of light for grow - you have less lumen per watt but higher energy density with a blue spec.
besides, bit slower grow rate buys you time and space if you look at this from the perspective of a MMG - you want quality buds and to get those you have to grow from matured plants. now maturing a plant takes 4 to 12 weeks normally and depends on the strains gens and not light sources or other environmental factors. now with a bit slower grow rate the size of the plant stays more manageable then one grown with HPS.

oh, and moving plants is no big deal - i move huge 6-8 plants already for quite some distance, just cover them up, if they still small pack em in a box and they good to go

you couldn't finish those in 2 month anyway if you want some bud out of this grow - just flowering takes between 7 to 16 weeks depending on the strain. so you will have to take em along anyways - either as plants or clones.

if you prune/top em well and do some LST (wiring them down so that they can't grow directly into height) you can keep em under 6" and get a huge an bushy plant with possibility for several huge colas in flower. and you get shoals of cutting you can clone.

and clones are great, they have the genetic age of the plant they cut from - so cut down the time of veg to gain a matured plant to flower, keep the plant sex you cut it from (so if you flower a clone you can determine the sex of your plant) and save you seeds, money and time later on.

thx green great help, so i think im gonna get another cfl which means i will have 4 bulbs, do you think thts enough? my space is just under 1 meter square........oh and whats MMG? thx m8
