Slight lightburn?
First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape. 2 full weeks old under 75% of 200W leds about +-45cm. Should I dim them a bit more/hang higher? Other suggestions maybe?

Curly young leaves (help)
I have a little problem with the plants in my indoor (70x79x160 with 4 airpots each of 12 litres) since 2 days ago are decayed, 3 days ago (Friday) I changed the lamp mars hydro ts600 (100w) for a more powerful mars hydro Fc300 (300w) I do not know if it is the change of format, the power of the knob I left it at half that is in theory 150 watts of its total capacity 300w and at a height of about 40 CM. The next day (Saturday) I saw that they were the same so I proceeded to leave it at 40 degrees of power and I gave them biofish fertilizer to see if it was a question of hydration but today Sunday I realize that they are still the same. I don’t know if it’s the light intensity with the new lamp or that I over watered them 3 days ago on Thursday (I watered them with around 550ml of water per pot) and as I said before, when I saw them like that on Saturday I gave them biofish fertilizer, but nothing…

Late Flower Rapidly Yellowed Leaves
The yellowing leaves have definitely progressed quite a bit in this last week. Does this look like a normal natural late flower nitrogen deficiency? I still want to flush the plant, wondering if I should start the flush now because the leaves are already starting to get yellowed.
