bro i havent watered until runoff because i dont want to over water them and they are only 2 weeks oldIn the photographs the plants are displaying a magnesium deficiency as displayed by the upward curled leaf edges. The FoxFarm Happy Frog Potting Soil is meant to be used in conjunction with a commercial fertilizer program and does not contain enough nutrients to properly supply cannabis plants requirements.

I would purchase pot saucers large enough to contain the grow bags to catch runoff liquid when the plants are watered.
As previously mentioned the daytime temperature is lower than ideal for plant growth. 78.8°F − 32 × 5/9 = 26°C would allow for faster growth. I would raise the humidity in vegetative growth to 65% to lower transpiration from the plant leaves.
Regular Epsom Salts are Magnesium Sulfate and can be used as a source of magnesium supplement. You can foliar feed Epsom Salts at 2.5-5 millilitres per gallon. Epsom Salts can be used at 1-2 teaspoons per gallon as a magnesium and sulfate supplement to treat a deficiency. Some people have reported nutrient burns when using a higher dosage of Epsom Salts with a nutrient mixture.
