Purplematic / Hulkberry Auto balcony grow

still do not have to water them regulary. soil is still moist in most parts just under the surface. i think i gave them water like 2x and also when i moistured the soil before transplant. day 5 - Purplematic currently is 22 cm and hulkberry 18 cm in height. purplematic shows first sings of flower today. they also got another small 500ml watering with some BIO enhancer day 7 - i am really not sure how much i can get out of these 2 autoflowers but next time i will start in the end pot instead of a jiffy and also not put them outside if there is any bad weather going on. seems like this 2 things really stunted the growth of them
