from the pics, the plants have that "overwatered droop." this makes sense since you say you're watering every day. looks like the lower leaves are burned a bit. feed once a week, and let the medium dry up a bit. in between feeds, water with properly ph'd water. since you're kind of using a soilless type mix, i'd drop the ph down to around 6. sounds like your medium is probably pre-ferted, and you've amended it with more. this is fine, but remember when adding nutes to the water, use a reduced rate because of the nutes in the medium. those temps. are a bit high, maybe throw a fan on em.
