Heirloom sativa, whats wrong with my plant?

Hello everyone I have plant in dwc reservoir that was healthy until i flipped it to flower. Ever since it's just been a mountain of problems.

Strain: Bagseed heirloom sativa (possibly from kenya)
Flowering time: 3-4months from flip its closer to 4-5months after flip sorry i was high
Plant max nute ppm zone: 400-600 (0.8-1.2EC)
Current Feed: FLoraNova bloom @300ppm
Growing medium: 3liters DWC

About 3 weeks ago I had what I felt was phosphorus deficiency that appeared when I flipped on 8/8 so I tried FloraNova at various strentgh levels all the way to 1200 last week. I felt I have made it worse, I lowered it down to 400 about 4 days ago to help it recover from shock, but the next day ppm had risen to 500 and water level was also almost the same. Yesterday I brought down the ppm to 280-300 range and today when i checked the reservior again, water level had fallen. I filled it back up with fresh water(50ppm) to the level but now ppm is 400? And this problem isnt getting any better either. The leaves are just dying and I cant feed higher ppms or it gets worse. What do I do? And is this really phosphorus deficiency or something else?

So you flipped a month ago, you might have to flip harder.

Keep the ppms on the low end and keep your eyes on the roots. Shine a light and take a good look at them.

You haven’t mentioned your pH in all this.

You have lock out. Go with fresh water. clean the roots and spray leaves with nutes. or they will die.
DWC is not for the faint of heart. Things go wrong fast. I've come in to plants with no conection to their roots. Just fallen over stem rot. All deficiency's will show with lockout. These plants need food.

PH is never a problem with FNB

What is fnb?

Are you using Flora Nova or Flora Nova Bloom. Flora Nova has Ph problems in DWC

It's Lucas formula I guess old school, but it's all I still use from seed to flower. With HP soil in pots now. Used to DWC.
Look up pineapple express g13... https://www.rollitup.org/t/pineapple-express-g13-labs-seed-to-harvest.344359/
It's a good read all about DWC.

I'm using floranova bloom, and the ph is pretty stable at 6.2 max even at 300ppm strength. Usually full strength will give me between 5.7-5.8 and yes you're right its the lucas formula. How should I go about spraying fnb? and at what ppm?

These are the photos I found. Hoping someone can take a look and tell me what happened after flip.

I also have a bottle of florakleen. Can i add that to the fresh water or its a big no no?

Since the last time I posted here I did some research on what I am doing wrong and landed up Dr. Grinspoon strain on strainHunter's forum. I am certain that that plant is the closest my plant resembles to. According to them the plant has required very light feeding through out flower. I came upon very few grow threads here that have documented pure sativa plants. I am going to take this opportunity and document my findings here from now onward to see if I can succeed.

Day 38 of Flower

I have been feeding fresh water for 2 days and then switched to a fresh reservior of light 132ppm feeding of 14-12-14 npk since thats the closest I have to Green House Seed co's Long flowering formula (18-12-18 ). Checked today morning and plant has been taking up water which is a good sign, as well as the ppm has gone down in the resevior. I am now slowly pushing it up by feeding 190ppm(0.38E.C) for today.

Pics from today:




Does my plant looks like it need phosphorus and calcium? I am seeing these black/dark brownish spots on older leaves as well necrosis on others.

I wonder if this

That could be the case too, although this is a clone of a plant I grew last year and that plant transitioned ever so slowly.

That 8/8 is august 8th bro.

I am starting to think it is indeed not flowering at all. That or I dont have the nerves to be patient with the plant.
