Not Normal! They are in flower week 3? I would say more Vege nutrients

--- yellowing near the top this early isn't normal, but it's not bad so far,... I need info-- your set-up, nute's and feed schedule, pH readings and any sudden shifts in it, etc.,... at this point the symptoms are kinda generic; the pattern of yellowing is similar to N defc. but that affects lower leaves first, not uppers,... I'm thinking more along the lines of a micronutrient defc. starting up,...

Smoke weed every day.
OK so I have a dwc with 6 gallons of RO in it.
The feeding schedule is as printed off of the GH website. Cut in half. Flora trio. Week 9 of nutes.
25ml micro. 50ml bloom. 30ml liquid koolbloom. 5ml floralicious plus.
300w(138true) LED. 12inches from top of plant.
2x4x5 tent 6in exhaust fan. Oscillating fan.
Large commercial air pump.
All was well up until I switched my ewc tea from great white to mycogrow soluble. Though I can't see Bennie's messing up the rez.

Air temp is low 70s on, high 60s off.
Water temp has never been over 72.5.
Ph has been steady 5.9. Still at 5.9.
Ewc tea with ancient forest, great white, and hydroguard for the whole grow.
Up until the switch to mycogrow. Shortly after the yellowing started.

...thanks Budz! Well, the nutes NPK balance looks good to me-- extra PK from the Koolbloom 
...Some N from the Micro,... and it's all at half strength,... the lowers aren't showing the yellowing, right? ...reduced dosage might be shorting her on secondary/micro's (S defc. is one that causes overall yellowing, no spots/necrosis, and is immobile, so it hits uppers mainly before progressing downward),...but I wonder-- you using any Ca-Mg? Another thing that caught my eye, the LED is only 1' away from the tops? That might be a bit too close, not enough to burn, but enough to stress; Mg and chlorophyll are literally link hand to hand, so to speak,...the intensity could be beating down on the chlorophyll stability,.. can you raise the lights up to 18" and give a dose of Ca-Mg? try this and see if it halt progression after a few days,...:smoking:
