My very first grow

Passion Fruit looking sickly this week , leaves (mostly top newer growth leaves) feel dry, paper thin and look droopy/wilted . I thought maybe needed a good watering , did that no improvement , thought light burn? But light intensity not very intense. And other plants doing well . Temperature problems? Has been pretty cold at night . Nutrient deficiency? ? Not sure but hope it improves. She is only starting to make tiny little airy popcorn buds if you would even call them that . Hmmm 🤔 so sad tho😭 . As for sour 60 she is doing pretty well I’d say she’s a tiny little thing still but buds are progressing along , she smells wonderful and is covered in trichomes. Some of her Calyxes have a pretty purplish hue , even the lowest branches’ bud sites calyxes are developing nicely. Starting to fatten up a bit . Considering getting some nutrients to help them put on more weight , we’ll see if I can squeeze it in the budget this month . Two seedlings sour 60 and LA Berry growing a little slow I’d say , thinking it’s the cold weather . Purchased a tent and heater should b in this week .
