Need help. Am I in trouble?

[Scolwell19]

Hey all how's it going. So a little background on the grow. I am growing 4 different strains
Mothers finest
Bubba kush
Grape ape
An Durban poision
They are exactly 36 days into flower at the moment. I started seeing this problem about a week ago when I accidentally left the grow lights on for 18 hours straight. Befor this problem I had a slight mag/cal deff so I picked up some botanicare mag/cal to add to my nutrients. Btw in using full line of cyco nutes. The humidity is a lil low I live in Colorado so I try to keep it around 40. The temp is 76-80 with lights on. Anywhere from 65- 72 light off. I'm growing in coco coir an perlite mix 3 gallon pots. Don't know what else I should list on here. Any questions just ask. Im basically worried whatever is effecting my plants will eventually hurt the buds on the plant. Right now they seem to be uneffected. Take a look an tell me what you think.

I am guessing it is getting worse? How long were the lights off following the 18hr incident?
What is your ph of your feed? ph of runoff? ppm or ec?
Did you weave the net yourself? Not that i think its an issue, just that it looks a lot tighter and nicer than anything else i have seen.
Feel free to come join us in the Colorado Patients section, we have a good group of local guys over there always willing to help out.

Yes the screen was made by myself. And my ph is always 5.8 when I feed. I'm using a drip system that waters once a day for a minuet. An I don't know the ppm at the moment my meter recently took a crap : /

What is your PH man?
Lights won't do that to ya, just resume your original light schedule, and don't worry about that.
Pics 2 and 3 look like hungry, but pic 1 shows nute burn AND hungry.
Are the brown tips and edges from before the yellowing?
You're using hydro PH for reference since you're in coco, right?View attachment 2628921

Oh and the lights were off for 10 hours that's all the time I let them be off for due to heat issues durring the day

You should be fine then, use the guide he provided and try to fix the deficiency.
How long has your PH meter been out?

My last grow was a closet CFL grow, and even though I was just using 300w of CFL, I ran lights on at night, so I wouldn't have to worry about temps at night or heat during the day.

I think the ratio is out of whack. Not enough N and too much P K.

Man, stop the panic.
Your accidental light schedule for one day will NOT make your plant look like a deficiency or burn.
You say you are feeding, so give us some new pics-it has been a couple days since those pics.
I would like to see what, if any change since you posted the last pics.
You never did clarify if the burning was from before, or just recently after you fed.
That info would help, but I still think you have hungry plants.
If those were mine, I would give a shot of veg nutes for the N, and also an extra shot of Ca, and Mg, just for good measure.
