Honey Peach CBD Outdoor Grow

(10/6) so its the end of week 5 and the plant growth has really dwindled as they start flowering. Lots of cloudy weather and inconsistent sun. The larger one is obviously further ahead then the smaller. Observed some aphids and what appeared to be thrip damage on the plant early last week and so had to do some spinosad treatments. Bottom leaves have begun to yellow and i dont know if its nutrient lockout or what. Havent had the chance to do any soil or ph testing because ive gotten a little discouraged. I think suboptimal root growth early on because of mediums being a little too wet and the constraints of the peat pellet have hurt the plants true potential. Next grows ill try just going right into the 3L soil outside and not messing around with the pellets in the window. They looked realy good there but maybe they didnt like the shift to outside.
