confusing.. first you state 2 deficiencies and a nutrient burn, but your advice is to cut back on the nutes..

anyway, we need more information to help here.
especially, medium / age/ potsize/ when transplanted/ PH-Levels/ how many days in flower and especially what you feed so far.

more pix!

everything else is speculation.

(my firs guess is a calcium deficiency as well, which can also be a ph-issue)

Thank you guys. I stopped feeding the plant fertilizers a couple of days ago, thought of flushing it the last 3 weeks or so. Should i go back to the fertilizer?? Am using miracle gro 18-24-16.

i wouldnt go back.
as you are planning to harvest in about 3 weeks.. no need to flush if you feed 3 weeks water only!

Is it in Soil? That looks like a calcium def to me.

And ive had ALOT of calcium issues (grow in coco).

Ive successfully used dolomite lime (2tblspns per gallon in coco, dont know the soil amount) or calcium nitrate.
