Strain: bridezilla (GG4 x Wedding cake)
Photoperiod
Age: 5th week of flower started today
Nutes: jacks 3-2-1, as directed
PH of run off is 6.3

My leaves darkened significantly over the last week. No swollen, downturned leaves. Dark veins initially, then progressed into leaves darkening from centers out. At first I thought it was purple color of indica, but then I realized this might be Nitrogen toxicity.

Last night I flushed with 1.1 grams of Epsom salt : 1 gallon water, then provided 1/4 strength part A jacks nutrients. I did not use part B of jacks (it has highest nitrogen). (Hoping I did the right thing here)

Questions:

Do you think my plant is going to be usable or will it likely taste like grass?

what do you think I should do with nutrients?

Thank you, kindness is appreciated. I’m not very experienced.


Jacks part A: 5-12-26
Jacks part B 15-0-0 (calcium nitrate)
Epsom salt (magnesium sulfate)

It is showing purple either from genetics or low temp you can see that on the 2nd pic up from the bottom

I would feed it to much more n mind

This confuses me

Jacks part A: 5-12-26
Jacks part B 15-0-0 (calcium nitrate)

I’m sure there a jacks guy around here somewhere

Thank you
I appreciate your comment.
I will feed normal again on next one.
The temp is low, and it’s an indica dominant hybrid. Purple makes sense.
