I started a basil plant using the kratky method, which I'm growing inside under a grow light - first time trying this.
The nutrient solution I'm using is master blend 4-18-38. I'm using 2 grams per gallon of masterblend and calcium nitrate, and 1 gram of epsom salts.
Plant has been in solution for about three weeks now.
The first thing I noticed which got me concerned was one leaf had a brownish border around the leaf. I cut that leaf off.
But looking at the leaves generally, they seem a bit on the yellow side, somewhat pale.
The plant does seem to be continuing to grow slowly but surely however the coloring of the leaves doesn't look very healthy to me.
I'm guessing this might be caused by a nutrient imbalance? Or could it have another cause? Any suggestions on how to correct this would be appreciated.
