Did you hit it with cal Mag...tomorrow is flush day..thinking of flushing with distilled water at 6.3ph with cal mag..

Yah I gave it cal mag since i noticed it after I flushed - seemed to help but I had worse news this morning

Big ol bannana in my bud - got the clones for the two plants that have them from dispensary bag seed - so was most likely a tranny from the get go - so now I'm just going to give them plain water for the next few weeks and see where I am at then -
Unless the cal mag made it happen lol

Just took a better look..luckily no bananas, I think they look good for day 18 of flower..some of the leaves at the top are spotted..I'm thinking a Magnesium deficiency..in reading they say 2 teaspoons of Epson salts per gal of water...been 55 days and I have been easy on nuits and have not flushed as of yet..thinking its time for a flush.
question...
1)Should i flush with just Ph 6.3 water
2)Should i flush with Epson salt water 2 teaspoons per gal Ph at 6.3
3)Should I flush with cal mag
Any help would be well appreciated
