Gonna follow this one. hopefully you get an answer on this soon.
have you looked into possible nute lockout?

 

[Emilya Green]

tell me what you do to adjust pH

 

[Emilya Green]

oh wait.. this is an organic grow? no synthetics? so how are you adding all this stuff, was it a well cooked soil to start with?

 

[Emilya Green]

I invite you to look into my current organic grow, and see how I supplement a super soil with mineral amendments. You appear to be experiencing a macro deficiency and I recommend a top dressing of 5-5-5 to see if that affects it. I had this happen when I tried to rush my soil, before all the components had baked in really well.

Remy I kinda get the feeling shouldn't be nute lock out with a organic soil,also it's happened to both sets of girls I've flipped. Thanks for the response.
Emilya yes I believe it "cooked" long enough as most of the ingredients are premade , also the veg cycle has zero issues. Now I could be wrong but if soil was say hot the younger the plant the more susceptible to soil "burn".?.? I recall reading some where some time ago that there is a deficiency where the part of plant directly under light yellows and the part that's not doesnt?? Also I've noticed on the older set of gurls main stem is starting to yellow,could this be root bound or Idk root systems not big enough to feed plant???? Like I've said I'm stumped lol

It appears to me that although your soil had enough free nitrogen to get you through veg, the amount of broken down bloom nutes is lacking, and your plants are starving for nutrition. You might want to look into a compost tea, made to enhance flower... but you might also want to be looking into an organic line of nutrients so that you can supplement your soil while you figure out what is missing.

I wholeheartedly agree emilya. Compost tea works wonders. It gives your plants everything they need. You can supplement as you go if you see defs.

Been using it for over 2.5 years. I will not change to anything but compost tea. Look for a book by dr. Laura engram.
Not sure if I'm spelling that correctly but she did extensive work on compost teas and fungal and bacterial soils.

Amazing read
