Seeing distress in plant ( flower week 4 )

Everything seemed good, except for I've noticed distress in one plant- the bottom leafs becoming yellow/sick- falling off easily. The veins of the leafs also seem brighter than my other girls (same strain).
Using Fox farm trio, ph about 6, in soil
She does seem to still be growing her flowers, any ideas on what to check first would be a great help! Thank you.

I'd suggest moving that pH up and down the scale of 6.2 to 6.8

Meaning. Go to 6.3 next feed then 6.5 the feed after that then 6.8 the feed after that. Then gradually back down.

Repeat until harvest. 6.0 is too low for soil. And adjusting the pH up and down will allow the plants to take in certain nutrients easier at different pHs

First feeding after flipping should be a full veg feed. By week 4 they will require cal mag. Both provide the nitrogen needed for early bloom.

I feed with nutes one day,, then water plus cal mag next feeding 5 ml
Do you think she needs more cal mag?

Thank you for your reply. Ive noticed it is harder to pH the water when using pH up then it is when using pH down...like its hard to see the color change to compare on the bottle. Any tips on that? I hand water and likely the ph fluctuates between 6-6.5

Sounds like you are using strips or drops. I use a pH pen for accuracy.

But just make sure you are doing what I suggested specifically when you are feeding nutrients.

No! No more unless you’re in straight coco running drain to waste.
