I'm starting week 2 of flower on these gg4 and noticed the lower leaves are starting to turn yellow/rust and die off. Any help is greatly appreciated. Thanks on advance!

Yes I run full line of cns17 botanicare with additives at 1/2 strength in ebb and flow. I've never had issues until now. My initial thought was calmag but not too sure. First time dealing with gg4

you could try upping the dose cause it sure looks like a calcium def.
 
I'd look at a few deficiency charts ....it doesn't look like a cal mag issue to me and if your temps are good and not getting to cold during lights out or night time you have some seriously purple stems seems like in one of the pics above . I would look into the def charts to see what's up and I'm not 100% sure but it almost looks like you have munch marks from a pest so you may wana look over your plants real good ......keep in mind the purple can come from cold temps and some strains do it no matter what but your stems look completely purple and I know there's something that can cause that if the plant is lacking it .....I'm just to stoned at the moment to remember what it is .....good luck

Yes hydrogrowlover I did switch straight to flower nutrients. Is that where the problem lies?

No idea I am honestly a novice but I found I had problems switching straight over. I have read conflicting sides of what to do when you flip so a more experienced person might be able to answer that. I just know that the first 2 weeks of 12/12 you are stretching and to me that means grow nutrients and when flowers appear around day 10-12 that's when flower nutrients are needed. So maybe there is a deficiency there, meaning it might not be a cal mag problem but a whole nutrient problem? Can we see a picture of the whole plant? Is it all the leaves or just a couple? Have you tested your ppm/ph on your runoff, if you are soil, or tested your reservoirs ppm/ph? Have you changed anything in your normal schedule, added more nutes, fed more/less, feed nutrients every feeding etc? We are working with limited information to help you out. The more detailed you get the better.

I'll get a pic later it's just a few leaves towards bottoms of plants. And ppm in res is 1190 ph is 5.8 same schedule I've been running on other strains with no issues. Thanks guys!
 
Ive seen that in hydro grows a few times but my newbie friends couldnt figure it out and just kept adding more cal/mag and other feeds.it could be over or underfed...is your p.h stable id check 1st?theres wasnt and they died after a week in a wilma system,id flush through with clean water check ph then start feeding again.imo.they dont need loads of cal/mag @ start of flower,you should use grow nutes 1st two week of flip then change to flower.if growing in coco you gotta watch the ammount of cal mag a defiency looks like a overdose"confusing" i know...
 
Yes ph is stable stays between 5.5 and 6.0 at all times. I've read from some people that gg4 is calmag hungry. Wondering if there's any truth behind that. Or if they just weren't happy taking the Bloom nutes to the face at the flip. It's only a few leaves toward bottom of plant. Do you guys think she'll thrive? All my tops look perfectly healthy. Thinking about upping calmag on res tonight. And should I add some grow nutes into mix now. They started week 2 yesterday. Thanks again guys!
 
would like to see the outcome to know myself what it is its definately something to do wit coco as thats only time ive seen it.
hopefully the new growth will be ok,if its just a few at the bottom

Dazzyballs I grow in perlite only in ebb and flow. I'll keep post updated as I see changes.
 
Ive never heard of anyone using just perlite on its own as a medium,do you fancy stiking a few pics. Of your set up on?if youve time.
