White Widow Auto Seedsman x2

Started grow room on 1/27/24, seeds began sprouting 1/29/24. Two White Widow Autos from Seedsman in the middle of week 7 (day 60) The taller phenotype is in pre flower and has ended stretching so I assume it's not only 1 factor that has prolonged its age to harvest. Both plants were infested with Gnats and brown mottling was present on fan leaves and side shoots alike. I also noticed slight webbing from whiteflies, however, I have resolved both pest issues with neem oil and allowing the grow medium to dry out. The skinnier and taller phenotype is displaying a phosphorous deficiency along with a small potassium due to the yellowing beginning at the old sites and the premature nature of its buds. The wider and bushier phenotype displays nitrogen deficiency and possibly sulfur too. I attribute the deficiencies not to a lack of the nutrients but a missing or weak microbial environment because of me not adding any Nutes. May switch to bottled Nutrients (Advanced Nutrients) to boost yields
