Ph is to high need to bring it down to 6.1-6.5 ish Its way to high even 7.0 is high the plant isn't able to absorb the right vitamins and minerals it needs in the 6.1-6.5 range its able to take in everything i suggest flushing it with some 6.0 ph water until the soil comes down that soil is way too high

ph isnt helping pot likes 5.5 to 7 but I would stick to closer to 6 dont worry about the bottom leaves thats about when they die off . I give my seedlings/clones a very weak nute solution I mix for 1 gal in 6 gal of water 2 or 3 days after transplanting then go up slowly from their. if your using ro water thats whats doing it . there are no nutes in ro water. tap water left overnight open to let chlorine evaporate works just fine and it will have minerals in it. my water is 7.3 and my current grow gorilla glue stopped feeding at the end of veg took two weeks to fix learned alot from nebulas tutorial now I give it nutes with a ph of 6 and they are thriving . other strains like thc bomb dont seem to mind to much . good luck hope it helps
