WHY IS MY PLANT DOING THIS??

Recently i have noticed the larger leafs margins start to curl down for no reason and i don't no what is causing it, last week i re-potting using organic soil and i was previously using MG multi-purpose compost, before the re-pot 1 of my branches suddenly went all droopy and floppy for no obvious reasons and shortly after new growth was turning abit droopy, i thought it was root bound and i was right hense why i re-potted, but i still seem to be having problems and the branch is still droopy, my pH is around 7, i use all purpose plant food at 50/30/80 npk, my plant is 8 weeks old and 3 weeks into flowering and is now budding, room temp is 72,1 fan on her for air circulation but i just seem to think something is up with her, does anyone have any ideas???

50-30-80? I've never seen or heard of a nutrient being sold with that NPK rating.. Is that a mistake? If your in flower you want your P in the rating higher than the rest of the numbers.Still they like some nitrogen,during flower. On a small doseage. You need to flush those ASAP!

i got told it was okay to use this as i dont have anything else and it say off the bottle, 5.0-3.0-8.0

Now that makes sense! How are you mixing it? At what rate per gallon?

Ga.

20ml plant food to 2.250L water, it says that NPK on the bottle

Go with GA here and flush that plant quick. I have found that manufacturers specification on their plant foods are far too aggressive, I usually cut the doseage in half or more. Also, you definately need to aquire some blooming formula plant food that has dimished nitrogen and increased phosphorus...increased potassuim also helps to increase foliage growth and also helps the plant to assimilate nutrients more efficiently.

it could also be under watering... same thing happened mine during veg but i let them be, and trimmed off the leaves that were curling just as it was starting to flower!

Repotting 3 wks into flower is bad. Should be finished potting before flowering. The lady is probably in a bit
of shock. also ventilation causes the leaf curl. I would get my tempsbetween 79 and 81 during lights on.
some species droop like that after a good watering. dont cut anything except dead matter. see how it does in a
week. dont get to worried yet.

Actually, repotting 3 weeks into flower isn't bad at all. What you want to avoid is repotting after flower and into rippening, which is after the plant is not producing any more foliage. The key here is to do it within the first few hours of the light cycle on the day of or the day before a feeding. I have done it many times without any ill effects.

dude had same problem, palns are green but claw, your using to much N, it can be toxic, and with changing your soil, i would flush the plants it cant hurt them.
