Hi Guys
Im on my first hyrdoponic grow, im using a recirculated drip system in a tent and im growing 6 x super skunk from seeds.
I germinated them in 2 inch rock wool cubes, and I've now put the cubes into my pots which are filled with Hydroton (clay pebbles). They are now 1 and 1/2 weeks old.
5 of my seedlings are looking fine but one of them has started to go yellow at the tips of the leaves.
Im running an 80 litre reservoir feeding all 6 plants, Ph is 5.5 - 5.8, im using THC grow nutes at 500PPM (which I suspect might be a bit too strong?). Lights are 3 x 600W HPS lights in cool tubes.
Room temp is 27c.
Pic is attached (pic 1) can anyone tell me what the probelm is? I've also attached a couple of pics of my setup.
Cheers
