Plz Help

I understand i have no pics again but i got a problem all 4 of the babies aint lookin too good. I skipped watering yesterday and when i showed up today 3 of em looked bad 4th one wasnt looking great. Most of the lower leaves were dried up and light green and the top fan leaves were dropping down. When i watered on friday i instantly saw improvement that night so im thinking this may be due to the fact that i skipped a day yesterday and the temp is around 110 now haha. Very Very sad anyone got any advice on what i should do. Definetly doesnt look like nute burn cuz the dried leaves are just a lighter green no spots on em or nothing. I was thinking of things i may have done differently and the only things i can come up with is i started using arrowhead mountain spring water instead of the tapwater.

also alot of people are saying to water until there is water coming out of the holes in the bottom of the pot. This never happens hehe I water 4plants in 7gal pot with 1/2gallon should i be using more water?

Sounds like you need more water and nutes as well, thats probably what the light colour is. Personally I'd give the soil a good soak with nutes as well and then leave for a day or to and re asses after that.
