Golden Apple Haze Super Sativa Seed Club

This was the last week of the 18 hour day cycle. Next week I will switch to flowering and look out for them to show their sex, after which I will eliminate the males and hopefully I will be left with at least four female plants. During the past week the plants have rooted properly and started to grow, they did a steady 10cm during 7 days. I noticed chlorosis on 3 of the plants. As a natural first reaction I studied the plants for signs of aphids but found none. Just a few thirps but I used woma soil clean and have not seen any since. Looking at all the plants I checked the EC of the run off water (usually I don't check the EC, only the Ph) and to my surprise it was quite high. Due to the fact that I only used Ph'ed water I can suspect that the problem is with the BAC Lava Soil. As it has let me down for the second time in a row I decided to switch to Canna Terra Professional for the re-potting of this strain. The new leaves on those plants seem more healthy after a small flush. Hope things go well.
