My dumb ass didn't change the nute soup for 3 weeks. I have 6 grapefruit diesel along with some sour diesel and some others. The 6 grapefruit diesel (none of the others) are looking like either Zinc, Iron, or Sulfur but I'm having a hard time telling which one it is. they have all been in the same tray so I'm guessing the grapefruit are more sensitive to whatever the cause is than the others. Temps have been a bit high (85) and humidity has been up as well (50). I changed the nute soup today with a light mix around 1080 PPM. pH is always 5.8. Suggestions?

I'm using House & Garden Aqua flakes A and B with Algen extract and Roots exceleratur. Aqua flakes A says 4-0-1 and Aqua Flakes B says 1.5-3.4-6.5. So when you mix them together does that make the nute 5.5-3.4-7.5?

Yes the numbers add as you guessed. Just feed with a balanced mico and you will be fine---You have a very mild mag def as well---Good idea to use a complete micro but by looking at the pics you have a mild zinc/maganese def.

Cool, thanks for the help. Is buddy the product or brand name? Would they have it at the local hydro shop?

Thanks!

Magnesium is showing as "v pattern folding from the center of the leaf blades out to the margins of blades in a lateral plain. all micro def's will show first at the top with new grow(yellowing from top down)---If it was just iron alone plants would yellow at an even rate from top to bottom. Major elements such as NPK are non-mobile and show def's on older or lower parts of plants---Most growers overlook the fact that plants consume almost as much calcium and magnesium as nitrogen. Hope that explains and helps..... Dr. VonDankenstine
