Please Look at Pictures of Sick Plants

Hey guys,

Any idea why these guys are looking the way they are? So far it's only effecting big leaves, these two are the worst of the bunch. I'm two - three weeks away from harvest and other that this, everything is looking just fine. The only thing I'm doing different is, rather then waiting for the soil to go dry (which takes about a week) I've been watering it heavily every 3 days, I'm using sunshine mix, which I thought retained a lot of oxygene but maybe I should be letting it dry out more?

I have these special stuff you can use (final flush) to clear all the nutrients out of the water and start again if you guys think its a nutrient problem, but the only thing I changed since last time was adding B viatmin to the mix.

I've looked really really hard for any sign of spider mites. I have no webbing and can't find any little tiny black specks moving under the leaves. So I'm hoping to god this isn't the issue.

Thanks for reading!

nitrogen def.....hav a flush 3 times the capacity of your mediumt hen feed grow nutes at 50% strenght (recomended dosage)

as well as yoru bloom nutes etc....

that could be several things tbh ... a pic of the plant itself would help more ..

Ok I've attached pictures of that plant as well as a few of its sisters.

So about that flush, I have about 100 liters of unclorinated water I can use, the flush will probablly take closer to 400 liters. Would it be ok to flush it with straight tap water, then finishing the flush with like 10 liters of treated water with 50% nutrients?

Thanks for the replies everyone!

what strain is that and how many days has she been in 12/12 for and what height did you veg at and how tall is she now jus trying to wokr out how big she is.....looks like a N def to me but this will decrease your yield size depending on when used thats y i asked how many days she is?

what ph is your tap water?

Strain: Lemon Skunk
Began Flowering: 42 days ago
Veg hieght: ~12 - 20 inches
Tap water PH: 6.5-7.5

Thanks Again!

my guess is turn back the nutes alittle, that late into flower i dont think the really need alot. i would just tapper it back and dont worry to much the damage is done and lower the ph alittle more high 5s. to me the tips seem more burnt as u go up the plant leading me to my conclusion. hope it helps

Ok so if its a N defficency, is it better to do the tap water flush like I mentioned, or should I just go to the grow store and buy something rich in nitrogen and start adding that to the mix?
