This is my third grow, ive now switched to full hydro with hydroton grow rocks in a waterfarm 8 pack. My plants we're doing great but now some of the leaves are curling and theres dead spots on some leaves, and the tips are turning yellow also, im going by the nutrient calculator on general hydroponics website, im using all general hydroponic nutrients and im vegging under a 1000 watt MH. My pH is also between 5.5-6.0 at all times, now i asked my local hydro store about this and they said its probably my ppm or a deficiency of some sort. but i really need a rundown on ppm and how they work and what i need to do to raise or lower it, ive done some research and i know ppms all depend on your nutrients and your water, or maybe its not the ppms thats why im asking you guys, this is the best place i know for information . Ive posted pictures as well.
thanks, russian
