Urgent! What is this fast reaction?

Hi All,

I think my plants are suffering nude burn!!
Help please, what is the meaning of all this discolouring?

I added Blackstrap Molasses to my nude 3 part mix yesterday morning. This morning, I feed again at full strength and now the leaves look like this! What do I do?

  9. 24hr Lights and ranges 22-26°C
  10. Humidity ranges 60-70% rH
    (I have a dehumidifier coming so I can keep it 40%)
  11. Removed the Humidifier to bring down the rH
  12. This question is irrelevant?
  13. Yes co2 … 2 bags Grand daddy bag and mushroom bag … ranges from 400-800ppm

  16. Not treating coco to a full hydro standard and have successfully grown my plant to week 7… just made a small error by trying something new…
    16b. I water 1.5l daily

Thursday, I watered with hydro solution mixed with 1/2 tablespoon of Blackstrap Molasses (unsulphured). Then Friday, I decided to increase the nude solution slightly higher and yesterday (Sat) refer to the photo for the outcome…
Yesterday (Sat), I did flush with normal tap water (pH is 7.5-8) and the leaves are still discolouring… the rate isn’t fast…
