I think it might a mag deficeincy? It's in my own soilless mis. 1/3 castings/ 1/3 moss 1/3 perlite. I also added lime blood meal and a tiny bit of bone meal to the mix. Should I add more lime?? Sorry about the pics thats the best I could do with the camera I have.

Did you use dolomite lime? That would be a source of magnesium. Tips burning on bottom growth could be potassium deficiency. You have a source of nitrogen and phosphorus with the blood and bone meal but no source of potassium. Should maybe have tried adding something like kelp with potasssium and micros.
You could add something like maxicrop seaweed to your water I think to get the micros and potassium.

thanks for the replies. Yes I've been using Espoma dolomite lime. As for the K I add molasses to my fert mix of guano and worm castings. I'm only by my second flower feeding so I'll see how that turns out.
