Mid flowering problems brown spots!!!

[Duck Commander]

Hi guys ive noticed some probs with my purple kush over the past few days some of the bottom fan leaves hae shrivled up and my top fan leafs now have brown spots all over them. Is it going to kill my lady or will she pull throught to harvest? It my first ever grow and its roughly in the 5/6th week flower (i think) what should i do. Im using bio bizz light mix and ph run off is at 6.2 i know its a little low but next feed im going to ajust Si

si have you flushed her? if not thats a good start. after flush about three days start up 1/2 strength bloom nutes and some cal/mag, watch for improvement if you have slow release nutes in dirt it may not work! good luck you will get more info from others , who know a lot more than i do!

think im looking at poss lock out of calmag as my ph is under 6.5 what is the best way to flush her out? how much ph water to 10litres?

flush three times the size of the pot, might be salts building up get it then the plant can get to the calmag. i put a little cal/mag with every feeding!

does it matter if i use tap water without letting it stand for 24hrs? and do i do it slowley or fast?

tap water is fine... just make sure ph is on point...

the slower the better... more time for the water to pick up the excess salts on its way through....

iguess that would depend on if your tap water is nasty! i use well water i give directly no 24 hour wait, i have been blessed with water so good i dont even use or own a ph pen... my next grow will be the test, i will grow three widely different strains with the same method to see if i will ever need a ph pen. all the pros use them, so i may pay the price someday?
