Nitrogen Burn? Help

Yo thank all of you guys trying to help me. My watering and feeding schedule was exactly like this.
Day 6: First watering after germination, 150 ml, 6.5PH plain tap water. about 150-190 ppm
Day 7: 300 ml, 6.5PH, plain tap water mixed 1 ml of %0.4 neem oil 150-190 ppm (i know that was ununnecessary but i have to do something about fungus gnat larvaes)
Day 11: 200ml, 6.5 PH %0.1 neem oil solution. 150-190 ppm.
Day 19: 500 ml water mixed with 2 ml seaweed extract - 4 ml fermented plant juice. 6.75PH. about 200-250 ppm. Run off 7.12 PH, 1200 ppm
Day 23: 500 ml water mixed with 4 ml seaweed extract - 6 ml FPJ - 8 ml Fish Amino. 6.3 PH 367 ppm
Aaand i think i made the mistake here for not plain watering after feeding and being impatient. Because some laves get criespier and discolored, also cotyledons have wilted and i believe that was N deficiency. Then i increased feeding suddenly.
Day 26: Total 550 ml of 120 ppm plain tap water. Added 120 ppm of calcium - 100 ppm of Mag - 10 ml fpj - 1 ml seaweed - 10 ml of Fish Amino. Final ppm 550
Run off 8.3PH 1200 ppm
after that feeding leaves got burned.
I checked side by side photos upper leaves still growing but bottom leaves got worser.

I'm gonna flush with plain water tonight and make an update in couple days. I thınk i learned my lesson or experience we can say. Hope this not gonna stunted i fucked lots of plants before because of fucking fungus gnats. i was hoping to get some harvest finally 
Photos at day 27 8 hours apart. I think upper leaves are still growing but bottoms got worser

What size of pot? Not enough water 500ml is like for a 1 gal container.
If you flush you risk depleting your soil…
Those light green crispy patches will eventually die off and go brown. Just focus on new growth as it won’t heal
Pot is 9.5L but not filled all the way 7.5-8L soil i guess. I am giving first half of the water slowly and evenly, wait 5-10 min and pour the rest slow and even. When i gave 500 ml 75 ml is running off, %15 of total given water.
Should i flush or not? Or just give plain water next 1-2 week?
Do you think can i get decent harvest from this plant, even 30-40g is enough for me. Im worried

Microbe Lift BCM is a big help to kill the larvae. Using diamatious earth is useless if your top watering, once it gets wet it's completely ineffective. So to counter that, plain ol playground sand about 1/2"- 3/4" deep across the soil surface will help keep them out. It kinda tricks them because they can't detect the co2 that fungi create and it's not wet. Keep an eye on the drainage holes if your using pots, they like to sneak in there alot.I'm gonna flush with plain water tonight and make an update in couple days.

I think you'll pull more than you expect. Autos can be quite generous with yield.
If your uncomfortable doing a flush, then just focus on good watering practices and keep it simple. You've still got plenty of time for adjustments if need be.
I am not a big smoker also im trying to keep my expectations as real as possible cuz i know i have shittiest setup ever.
Yes im scared of root rot a bit and wdym by good waterin practices?

He means don't overwater, don't underwater.

That run off can be misleading as it finds dry pockets and shoots through the media. Typically want to give the plant 15% pot/soil of water when it’s fully established. For the size of plant and pot I’d give it 750ml now and work to a litre maybe more if the plant is thirsty.
Plain water for now. Get yourself a base feed, even tomato feed if money is tight can work. Start at 1/4 recommend strength and work
Your way up.
typically yellowing bottoms = hungry. Yellowing tops = too much
I flushed with 1200 ml 6.5 water and my media all saturated. Run off ph 8.3 700 ppm. Hope it doesnt got root rot and will be fine. Will make an update in 3-4 days.
Yo it's day 37 today. Not given any nutes since flush and today i saw some deficiency signs. Gave just a tiny bit of potassium calcium and phosporus. Pot is drying much faster now, watering 500 ml of water every 30-36 hours. Leaves are dark green right now but maybe just a lil bit of nitrogen next watering for last time before full flowering. What you guys think?
