Will a humidity dome help speed up recovery or wil...

Well there's a few things that I'am noticing here . According to your stats your in soil . The PH for soil mediums should be around 6.5 -6.8 right now your PH is currently set for a hydroponics set up . So I would firstly recommend that you fix that , the root zone for your plant is too hot and your plant will get burns because of it . Once you fix your PH the yellowing around the edge of your leaves should slow and then stop all together . When you raise your PH do it in slow increments because if you don't your likely going to send your plant into shock , going into shock at that stage of plant growth isn't good she will stop growing for a good while all together or possibly die if the shock is to great , so again raise the PH slowly. I would secondly try to raise the humidity to 50% or above I would not use your humidity dome at this time tho because your plant needs fresh air now (for the carbon dioxide) . When plants are young a lot of their uptake is done through the leaves . The ideal humidity for when your vegging is 50-60% and in flower you would start at 50% for the first 2 weeks then lower it by 5 % each until your flowering cycle is done . You lower the humidity during flower to reduce your risks of getting bud rot and mould . I would also suggest a rooting agent as well as a chelation agent to help your roots and plant get back on track recovering from the minor mistakes that were made, you can use a number of things to help facilitate this process I personally would use Voodoo Juice and B52 but anything like those products is fine ( it will recover without them just take a bit more time ) . All in all your doing well , just a few things you need to fix and then you will be rocking and rolling !!! I hope this has helped you understand things abit better :) ! -Happy Growing!
