I feed every watering less than half of recommend dosage. I normally dont have problems but i also struggled with my current grow. I ended up mixing some calcitic lime in the top soil and it solved my problem. Looked to me like calcium deficiency Hey Doc what did the lime sort out, I’ve not heard of that before?

I know I Can Posted Saturday at 07:31 AM Share Posted Saturday at 07:31 AM (edited) The exact same thing (yellowing of leaves between the veins) happened to me using Freedom Farms soil. I would pH my water, and then get rid of the Chlorine, by using an air pump. It looked like a Magnesium deficiency. Then one day I tested my water, and the pH was soo high, off the charts. It turns out, bubbling water raises the pH, because it gets rid of the CO2. I had to re-pH my water. I was getting nutrient block out, hence Magnesium deficiency. Why did it take me so long to learn this. I hope this helps somebody else. Edited yesterday at 01:26 PM by I know I Can Quote Link to comment Share on other sites More sharing options...
