Does anyone one know the deficiency causing the le...

I've just taken a look at your diary and you are MASSIVELY overfeeding this little lady (and your other one) with Grow Big... I never use more than 1tsp and you're using almost 12? Not even Fox Farm's feeding chart calls for that much .... So what has happened is that you have a lockout of several other nutrients. I would suggest you do a hard flush to get rid of the excess/built-up nutes and salts in your soil. Growing in 5 gallon pots, that means running 15 gallons of pH'd water through her.... In the last gallon, put 1/2 strength NPK nutes (but at the MAX use 1 tsp Grow Big for this) ... and let her dry out before watering her again. Take the time while she's drying out to go back through your nutes and look at what Fox Farm recommends as a feeding schedule - and CUT THOSE RECOMMENDATIONS IN HALF when it comes to the Grow Big... Big Bloom, I've found, is a good nute and well tolerated by weed as is Tiger Bloom. I'm also wondering if you REALLY need that much of a dose of Sugar Daddy... I'm unfamiliar with it but it does seem excessive.. I'm not saying it would affect your grow but really just trying to save you some money! Check that dosing recommendation, too! Good luck!
