Dead, dying or there is a chance?

[Filthy_McNasty]

Brown pistils at the end of week 7, autoflower strain? Doesn`t look normal to me since I have had an issue with yellowing leaf edges?
I was late introducing nutrients (Gaia Organics) so I am concerned this might be nutrient deficiency.
Close up photos are only 2 days apart, progressing quite quickly .....
Temperature 22-24 C, RH 45-50% . Lights are 26-28" at 50% , Mars Hydro TS 1000, I doubt it is light/heat burn , might be wrong....
Any advice much appreciated!

The yellow edges is that old damage like did you have the light to close at one point or is that recent and you’ve always had the light at 50% and raised to 26”-28”

Check there’s no bananas around if there are and they pop they will stain the pistils yellowish

too much light, nutrients and watering

Try adjusting your nutrient mix see if it helps.
