need health guru help please?

My plant is AF speed devil at day 17 I have curling and some that look like canoeing...while in seedling stage in humidity dome I had a 17 hour power outage which killed some plants but this made it so far...I have nice root system going white as snow...I am using GH flora series 3. in my 2 week I have just increased my nutes to about 460ish...I was looking at a nitro def. I thought had some yellowing of new growth but increased the nutes and they look a lot better but the curling etc...

Plant looks fine except for being upside down, my advice would be to just up your nutrient solution and bit.

Thanks Medic +rep...being new to growing I am hoping my skills are better than my photo's! I will bump the nutes up maybe 50-100 and go from there...being that the plant is an AF I should see sex in the next couple of days...next week I plan to go to flower nutes...and will res change...thanks again kindly!

ok so at day 15 I had health issues it seems from the pics above...I did a res change with RO water instead of my tap since i felt urgency was required and didnt have the time to air out chlorine...now my plant is coming up with these yellow spots on the first two fans and seems to be creeping...any ideas? I think I know what it is but I would like to hear from the experts and see if I am learning any thing lol...day 18 of my stunted AF speed devil...nutes at 470ish 5 gal dwc...thats a chopstick securing the plant since the plant seemed to out grow stem...

spots are getting worse tops look fantastic...my ph was a little low but it jumped back to 5.7 overnight...I want to bump it up .1 but I use baking soda LOL so it's difficult to get a .1 from it...so I figured best to leave it alone until week 3 res change and hit flower nute time...still no signs of sex...day 19
