What lighting are you using, and how long did you veg?@just grow it, do not be concerned the lsd yields well in my opinion. Grew 15 seeds of this and had probably 5 different phenos. The 3 to look for are as follows one will smell like lemons and be fairly bushy and yield well, another one will have more crystals then the rest and stretches during flowering and last pheno I found and like was more on the mazar side doesn't yield well but really stones you.
Included a shot of the second pheno never kept this pheno really enjoyed the taste and high on the lemon pheno. My average yield was about 2 oz per plant in 2 gallon pots.
