My plants are suffering .under chilled growcraft x6 They’re in coast of main organic stoning ton soil. (Seed starter soil in solo cup for 3 weeks then stonington premium blend in these 1 gallon fabric pot. ) I know it was most likely because I was only watering RO WATER (Walmart bottled water) since it germinated PLUS I WAS under watering I think (I literally measured 2-3 oz of water for each solo cups.. It waasnt till week 2-3 I started noticing something wrong and now I’m week 4-5 and idk how to correct. They’ve been watered with tap water last 4 times now . Last 2 times of watering I tried to correct with 3-4 oz of tap water with a tiny amount of calmag (bloom city) I also mixed a tiny amount of vitamin c asorbic acid powder to remove chromeamine/chlorine) . I don’t want to add more cal mag or flush , and make the problem worse . This is my first grow. Wish I asked for help sooner . This ONLY effect the bottom leaves and it’s not working it’s way up 
. ALSO should I cut off any of those leaves? When and how? I’ve read leaves too damaged can’t recover.
