leaves curling up

jesus3 · Jan 9, 2008

i have a problem with two of my plants other two are ok.leaves are curling upwards for some reasons,in the beginning i think this is magnesium overdose but now i don't know what to do.they grow in soil,month young and 10 days in to flowering now.and those plants witch leaves are curling up have different leafs,then other two plants.i feed them with SCHULTZ Bloom Plus plant food every second watering time.watering them every third day,almost 1,5L water each plant.water is 6-6,5ph.here is pics with problematic plants.

.last pic is all four plants left are healthy but right side is with problems.

try giving nutes every other feeding.

i've only had that problem when i wasnt giving enough nutes. what is the ratio of npk it's getting?

also if the plant is budding very quickly it somtimes makes the leaf tips curl. and of course at the end, but 10 days in, thats not possible.

it could also be your ph. although 6 is a little bit low i usually have it at 6.7-.6.8. it more than likely isnt your ph though.

NPK is 10-54-10.i'm worrying about Phosphate level,this may is too high.and do not have good ph tester to say precision ph level,myshity tester measure just like 5-5,5 5,5-6 6-6,5 6,5-7 etc.and i feed them every other feeding with this food.

yeah, try to lower your phosphate lvls to 30 ish

forget the nutrients. water more often. that's the problem. Plus, check the temp. if it's too high then all the water you give will transpire.

jesus3 · Jan 15, 2008

temp is 25-27c lights on and 22-24c off.i have good ventilation in box.nothing is change all this time.leaves looks the same.i change nute formula to 10-15-10 N-P-K almost week ago.i'm still worrying about those plants. :confused:

nikita · Jan 15, 2008

as i said, try giving 1l/plant every 2 days. see the change. plus remember: active ventilation dries the leaves faster than the only high temperature. your leaves are curled up in the attempt to lessen their surface, to keep the evaporation at minimum. it takes a plant to get to a noticeable size to start dehydrating in the same conditions it was ok while it was smaller. in my experience the affected leaves did not regain much of the healthy state but new ones were ok. etc. but first water more often. good luck

jesus3 · Jan 15, 2008

they got every watering almost 1,5l water each plant.humidity is 65% lights off and 45-55%lights on.and they are in 7l pots.

nikita · Jan 15, 2008

yea, i saw that on first post. but try giving 1l instead of 1,5 and 2 days distance instead of 3. damn, i don't know how to attach pictures to make myself clear.

Don't add more nutes. If it were me I would just water for a week and not feed them. When the leaves start to turn light green then I would start feeding again.
