My leaves curl up/dry. I attached a picture I took the leaf off the plant right before the picture, they just Die. I am using clones, and multiple clones do this. Here is my info on the grow: What type of medium; soil or hydro? SOIL What brand and type of soil? Fox Farm Indoors or outdoors? Indoors What strain? Random Bagseed, good stuff tho How old are the plants? probably 6-7 weeks What type of lights and how many watts? 400watt HPS How far from the lights? 2-3 feet. What is your watering frequency and source of water? every 3 days (I refill the bottles with tap water after I water the plants so they can sit for three days and let the bad stuff evaporate) What, how much and when was it fed? NPK? Fox Farm GROW BIG and BIG Bloom (going off of fox farms chart) What are the temps and humidity in the room? 70* and 35% humidity What size pots? 5 gallon Any bugs? Look real close. No bugs Any other pertinent info? Thanks for the help!
i'd flush those plants real good, what's your ph, sound's like you have salts built up in your soil. add some dolomite lime to balance it out after flush
