Week 5 gsc in flower. All leaves except sugar leaves keep turning yellow. All new growth turns yellow in days. Gave it 12-0-0 blood meal 4 table spoons and some recharge. Cut back on nutes for 2 weeks even flushed it 1 time… now I’m back to full strength nutes using ff. Per instructions on bottle.
The soil ph is 6.5 checked in 4 spots. 2 esky 300’s turn them down. No change it’s been drinking about a gallon every 4 days sometimes 5.i allow 1 day of dry reading for 1 day at the least never more then 2…
So any ideas?
PPM readings? Looks like nute overload, IMO.

Looks like to me a combination of issues. I see leaves curling which might could be heat problems from the light (??)
Also looks like the plant may have been hungry or thirsty.
Please don’t take my word.
Let’s call in the big guns like @Myfriendis410 @MattyBear @PurpNGold74 @Covertgrower Maybe they can help with your issues.

Excessive heat, nutrient burn, under watering, and too much light intensity.

All of the above. Especially the heat/underwatering. Ive seen this. She’s ‘finishing’ up off the strength of her foliage. Just gotta watch her closer.
Also blood meal is organic. Takes a bit of time to show up usually if ur using organics. N if ur just beginning its easy to overcompensate. All the white pistils (foxtailing) is more then likely a combination of the above.
Honestly at this point? Id flush her n try to ride those leaves as close to a week as possible. Maybe flush n feed PK immediately after but thats pushing it.

I grew out a couple of GSC’s and both were very sensitive to light: both showed bleaching on all top colas. So maybe phosphorus-hungry too.
You’ve got so much going on that it’s hard to tease out all of the problems.

Is that soil or soiless? Is it a Fox farm soil?The reason I ask is more out of research than anything because those guys gotbyou covered pretty hard there. My hypothesis is that unlike a true organic soil, man made built up soils tend to collapse all at once! They are doing great and then hit the wall so to speak. Whereas organic natural soils tend to slowly get tired. This is what ive noticed seems to be a common thread.

Finally figured it out. The plants almost dead and its calcium. All my plants are now showing signs. Of calcium deficiency.
So now …do I either give it a heavy dose of cal mag only and ph 6.2. Or do I let it dry out first?

Get that calmag in there! I was thinking cal myself (good catch BTB) but not tryna jump the gun. Dont nuke her. Most calmags have a good bit of N in it, but give her a full fledged dose
