Plant problem!!! 1week flower

hello....i am growing an arjan haze #3. it's in week 1 of flowering under a 250w hps. 2 weeks ago my leaves started to curl down and the margins brightened in colour....what is the problem..here are some photos

id say you have a ph problem and/or overfert prob..

if you want help on these forums you have to give some info for peeps to work with.

what soil
pot size
ppms of ferts and what ferts being used
water? distilled, tap, RO, well?
temperatures
humidity
light distance, air cooled, bare bulb etc.

more specific info gets more specific answers

off the top of my head id say check the ph and flush the shit out of it

Looks like a heat problem to me.

It also could be Mag def. If you are doing hydro and using pure water with no calcium or mag supplement then that could be it. esp now that you began to flower. But it could B alot of things depending on everything. Flojo is absolutly correct when he said you need more specifics. there is no way to know the problem without knowing how the conditions are. Good luck Pe@ce

i have a 9 litre pot with some balls for drainage........i have a computer cooler........250w hps at about 30 cm from the plant.....6:7:11 fert(foliar)....a good soil with perlite and the ph at about 5.8.....and i use tap water stored 3 days......( few weeks ago the tap water was the ph at about 7-7.5 but now my tap water has 5.5-6 ......and don;t know why is that different.....but i got my ph up with some baking soda....and i hope it's not to late). Oh and the growing is very very slow

p.s. i live in Hungary......so i don;t know your local brand of soil....fert..etc.

ok well first of all you need a larger fan to keep the tops cool.. 30cm is not very far away for a 250w hps.. you should be able to put your hand right above the top of your plant and be comfortable.. keep in mind the inside of a plant is up to 10 degrees hotter than the surface, so it can get steamy.. what are your temps?

second you do not want to foliar feed, especially with the lights on because the water droplets will act like a magnifying glass and can easily burn the leaves up.

your soil sounds ok, i would go ahead and water it with your straight tap water to raise the ph since it is higher. you want the ph in the mid sixes.

you probably want to find a fert that is 1-2-3 or as close to it for your npk ratio.. then you can feed the soil accordingly every couple of waterings..

change the other things and she should start bouncing back in a few days

nice call FloJo

ok...so i watered my plant today with some ph water 6-6.5 until it was driping from the bottom.....i put a 220v fan ( for bathroom ventilation) which is blowing directly on my hps bulb and i keeped the pc cooler witch is blowing on my plant.......and i will buy some nutes in about 2 3 days.......thank you man

no prob.. keep us updated in a few days with your progress!

hopfully they will stand tall >_<
good luck

new update.......the leaves dosen't look very healthy.......i want some organic nutes....RH 45% temperature 26 Celsius

first pic looks like a zinc def. other pics look like overfert.. i think you are having some nute lockout issues due to the ph of your nutes and/or soil.. did you get a ph tester?

i do not have a digital ph meter.....and i don't know where to get one from.......but i have some ph tests(even if it's not very accuarate)....i think i have a deficiency of all micronutes....because of my acid water

yup.. like its been stated.. fix your ph, fix your plant

ok so i flushed with 2 liters of ph water at 7.7(comercial non acid water) with 7.5 ml of nutes......i cant wait to see if she likes it.....so i found a digital ph meter but i'm going to buy after 1 week because now i don't have any money for now.....

looks like ur bakn it to me but the wattage ur using isnt even that high. most likely a fert and heat combo. how close is the light and how much do u fertilize?

the light is about 30 cm from the top and i have a fan that is blowing on the top....but i do not fert her regulary

ok so from the time when i flushed......it seems a little bit better.....the old leaves remained identical but the new growths look very good except the tips.....so it's growing again but still no sign of flowers.. only preflowers

if you add garden lime to the top layer of your soil it will raise ph in the soil up.but will stabilize your PH in your soil..and will not go over 7..and your plant will get lots of calcium and magnesium from the lime..that should help alot..next time you plant mix the lime in with your soil ...good luck...

thx guys....now my plant looks great....and it's growing really fast and healthy.....but i have another problem.....my leaf tips are curled down...here are some photos.....the flowering is really beautifull
