1st Stealth Feminized Grow

week 5 of flowering; noticed some burnt tips like 1.5mm all over the plant along-with curled down leaves. also top leaves shows some pink tint. even the buds have those pink tint in them. disregard the crappy camera as i could not capture it perfectly. due to some burn issues ; decided to give just one single feed of 500 tds in midweek where as all the other days was a flush with one day of seaweed and other just tap water ; all averaging to 100 tds. the plant looked happy at the end of week as a result. also tried leveling up the ph to 6.0 for flush. the smell is now normal through out the day and peak at night.
