Here we go again... Massive yellowing

[krunchbubble]

So yes... When I went to 12/12 i started a 1150ppm bloom schedule as prescribed on the GH nute calc. As the last month progressed, I have bumped the mixture to about 1350ppm. I have approx 35 days left in flower.

Im currently using this mix in my 50gal rez:
FloraGro - 250ml
FloraMicro - 500ml
FloraBloom - 750ml
FloraliciousPlus - 50ml
LiquidKoolbloom - 250ml

If this is nitrogen def, what can I add to help?
I also use three separate PH meters to triple check, as well as 2 PPM meters. I calibrate them weekly.

personally, i think your using to many products. to much of a macro or micro nutrient will lock out others......

im pretty sure you have enough nitrogen. you use shit loads more then me and mine dont yellow.

I use 6mL micro to 9 mL bloom per gallon, no grow at all, plus my supplements, this is on OG Kush varieties though and they like it light...

yup, this is a good mix. im using 6 micro and 10 bloom only, no supplements with the exception of liquid koolbloom once in week 3 and once in week 7, ppm's NEVER go above 600! getting really good weight with this system......

Krunch, Zen... Thanks for info... What is causing my horrendous yellowing?

You can't go wrong with the Lucas formula. I have grown a wide range of strains and they all loved Lucas (AK-47, AK-99, Agent Orange, Sensi Star, White Berry, Ice Cream, Blueberry, Double Straw Diesel, Hashplant, NL5xHawiian Indica...many more).
Some strains require a lighter strength Lucas than others but the ratio always seems to work for me (1 part Micro 2 parts Bloom per gallon).
In early veg I usually go with 2ml Micro and 4ml Bloom to start then bump it up if they ask for more...maybe 4ml Mic and 8ml Bloom per gal..
When my girls are put into flowering I usually start them at 5ml Micro / 10ml Bloom per Gal for the first week or so them bump it up until I'm at 8ml Micro / 16ml Blooom.

Lift one of the buckets out and see if it stinks in there.

Ok everyone... I flushed all night, and set my rez this morning with a basic lucas formula.

6ml x 50gal = 300ml Micro
9ml x 50gal = 450ml Bloom
Cal-Mag 4tsp.. I always have deficencies. I need to get my water tested.

PH 5.9
PPM 1150
EC 1.66

Heres some pictures:

PS my lone bubble bucket is growing incredibly!! And my new lil hempy starts are going whacko too. Those only get 8/16 lucas at about 1050ppm. Ill post pics of these if ya want.

less light for a week and higher nutes should get you through the end of flower.
