please.help...yellowing/spotty/brown wilting fans in that order

[rolme1kenobi]

Good evening. Im 2-3 weeks into bloom and 2 of my 4 ladies are losing fans very quickly starting from the top. They yellow then become spotty before turning brown and wilting...then fall off. And its only happening on half.of.the plant. The other half.looks like nothing is even wrong. I feed. Tiger bloom, big bloom, super thrive, systemic fungicide amd cal mag. Also use the foxfarm suppliment trio. Occasional silica as well. 3rd year doing backyard beauties and ive never had the issue. Biggest ive ever had and am hoping.i can figure it out before i lose em.

Please help.

Are you taking pictures at night? Not a good idea.

PH of nutrient mix going in?

Try to keep it around 6.5. Pen broke several weeks ago so ive been going without testing. 2 of the 4 girls are completely fine. They get fed from the same mixture. I have a new pen now and am going to make sure to test from now on.
