slight yellowing on the tips

[stanko]

Around 56 days.. The first picture is the youngest and is about two weeks younger than the others, the green ones that are just starting to bud, did start to show signs of flowering very late about day 40 i decided i would keep them outside which has speed things up.

i'm a little concerned that the youngest one (first picture short stuff random) isn't going to make it, leaves are drying up, becoming brittle and crumbling in your hand, the one in the second pic, i think has about 10 - 12 days left (im guessing never done this b4) meaning the youngest one would have something like 26 days left, ish...

<is the bra for your plant ladies? hahaha!>

i hadn't thought of it, but if i have that classic problem of getting buds to big, i can use it to support them.

Would you give them all nutes, or just the green ones that have the slight yellowing at the bottom?

 

[whatsgoodie]

All of them. They all need flowering nutes. That brown leaf crumbly crap is PK def. Potassium more than anything. It is classic K def. It's needed in flowering, potassium that is. Hit them with something high in PK. Not sure what nutes you're using but give them all a nice 75% str PK feeding. Pull off any leaves that'll come off as so the plant doesn't waste vigor trying to restore or fix the necrotic leaves. I.E: Most of the brown/yellow crumbly ones. Plant will not die, it'll just create airy buds if you don't fix the problem. I had this problem in my first grow as well. I promise you that's a potassium def!!!

he's right about the deffinciency... check your soil ph... when ph runs to high in soil it locks out the potassium....

thank you guys, i've pulled off most of the dead leafs, and given a good strong feed..

i guess i have been under fertilising, the nutes i have suggest between 1-5ml per liter of water and i was doing 2-3ml per three liters in fear of burning them.

 

[JM]

yup... sounds like thats the deal bro... didnt realize ur fert sched was low.... good work man... follow tbm's progressive bump-up advice...

 

[stanko]

Don't go straight to 5ml/l though, she'll cringe from that.

Opps... i didn't do the full amount i.e 3ml x 3 liters =12ml i put in about 8ml hopefully she will be ok..

and after the feeding last night the one i had repotted, (originally the smallest of the two that didn't autoflower fully) has now become my biggest. standing at 2 foot. i think she grew an inch or two last night..

 

[stanko]

is she ready to be chopped or should i keep her going for another week?



lol i know they say when 80% brown/red hairs, i think i'm about 60% to 70% never done this before. so am quite nervous about cocking it up.

I'd let it go another week or 2... the real test it to get a good jeweler's loupe or magnifying glass and look at the trichomes... you want about 50-80 % milky and the other percentage still clear....

they look like they have a little bit to go to me though...
