whats up with the leaves

Hi buds my friend came round today and said i need to give my plants more food im not so sure this is caused by needing food i understand the red leaves is cold on night but why do my leaves look all serated and curl up, i dont think its the light heats at 22-26 lights on and off about 19-21 lights off humidity around 56 lights on and around 59 lights off, i have just ordered new carbon filter and fan to try improve the humidity the plants are 6 week in flower and doing great apart from the leaves i feed ec 1.0 or ppm 1020 and i top up to 1.2 ec with buddy which i think is booster also the plants are in 15 litre airpots with coco soil and clay pebbles
Thanks for any help buds

no 1 any ideas

Everywhere i have looked thery all say heat stress but i cant see it been that bud im going to make them a new mix of food today will try them on a higher ppm maybe 1300 and top up with buddy to maybe 1400-1500, think i may have to higher the light too or get another fan on it

usually heat .. but honestly they look fine.. i wouldnt even worry about it .. they are stacking up.. nicely.. and they look healthy otherwise.. is your buddy a better grower then you? does his or your buds come out better? or ..

anyways.. check your TEMPS at canopy level.. if u have a laser thermometer .. laser a fan leaf. see what temps u got .. most people mistake room temps.. and canopy temps as the same thing.. there completly different.. the air in my room doesnt go above 78 with lights on.. but the canopy temps are at 82-85.. but because of the way i use my fans to bring air from lights out room into my lights on room.. and back and forth.. the plants that are producing Co2 in the lights off room.. are providing extra co2 for the room with lights on.. which allows me to run a little hotter temps.. but this grow is turning out AMAZING like normal..

but the plants are looking great.. 1 thing u need to be aware of.. is.. the plants directly under the lights will use more water.. and nutes then the ones around the edges.. so u could have some plants that need more nutes.. especially if ur running more then 1 strain.

it could also be that u dont have enough air movement so ur plants leaves are heating up.. u need to remember they are like little solar panels.. so ur air temps.. dont matter as much as ur leaf / canopy temps.. and ur root temps.. another thing. i learned.. if u have cement floors in ur basement that your growing in.. to raise ur floor with a 2x4 frame and a few sheets of plywood. covered by some sort of plastic so it doesnt rot.. but it helps alot to not have cold roots.

Cool thanks bud, no my friend is not better grower than me we r both new and learning bud also i have my plants raised about 5 inch from floor using a stand, Iwill go check canopy now i always go on room temps i should'nt do this, I will try and remember also i have only a 465 cubic feet extraction fan and my room is 735 cubic feet but i have just purchased a 1000cubic feet fan and filter 8 inch do u think this may help clearing my room of bad air and humidity or should i have gone bigger bud thanks

dude your doing great.. don't worry bout stuff.. and try to keep shit simple...

how many grows do u have under your belt?

+1 You're new at this? You must have a green thumb

As mentioned already your temps may be a tad high but the plants are healthy and look to be filling out nicely.
