yellowing leaves during flowering. no nute grow.

no nute grow here. i am about 6wks into flowering. should i add some nutes? or is it another problem?

5 gal buckets.
mircle grow soil
regular tap water (no ph checking)
350w HPS light
fans blowing for circulation.
temps between 64-78 64 is night temps

heres the pics. any help will be appreciated. thanks guys! keep it simple!

Which blend of MG are you using?.

Could be the plant is sending all the nutes it does have to the flowers. This happens late in flowering. That said, some bloom nutes could only help and they will increase your yield.

im using miracle grow potting mix with micromax. thanks for the replies

pics of the plants are in my siggy. they are coming along well ive just never made it this far into flower so im in uncharted territory here

Did the discoloration just begin, or did you notice signs of this during veg?.

I started out with MG soil prior to going organic, and wanted to rule out your water being the issue prior to making any recommendations. MG soil has a tendency to go out of balance over time, particularly when combining it w/unfiltered tap water. When this occurred, I treated the imbalance with a balanced approach.

0.21 - 0.07 - 0.14

The above was the original amount of inorganic fertilizer in your MG blend...notice what's missing. Therefore, I would flush these ladies, after you drill a ton of holes in the sides of those 5 gals. When they dry, re-apply a balanced nute upon watering, any 10-10-10 will suffice.

Good luck!
