Hi. I have 4 Kali Mist plants (LST) and 1 Afghan Kush in day 39 Flowering. There are some problems with them and I'll appreciate any help. Here are some pics:
First a general pic (it's just after watering so they are a little droopy):

Now the problems:

![P1000594.jpg](/data/attachments/1545/1545875-9c77a1805acf0e91c86b685860a323ff.jpg)
The yellowing of the tips first appeared around 20-th day of vegging. It affects mostly one of the plants, which is also affected by the browning. The yellowing appeared on another of the plants 1-2 weeks ago.
Now the browning:

It's only on these three leafs. Do you know what is it? I hope it's not some kind of fungus.
Here is some info on the grow:
Air Circulation: Big fan![Smile :) :)](/styles/smilies/icon_smile.gif)
Light: 400W HPS
Temps: 64-75F
Humidity: 70-95% (I know it's extremely high. I started using dehumidifier and I hope to lower it to 60-70%)
Ferts: Bio-Grow, Bio-Bloom and Green Sensation
PH: around 7 I think (I use the color strips test)
The feeding (Days in flowering):
Day 3
Bio-Grow: 1lm/l (about 4ml/gallon)
Bio-Bloom: 1lm/l (about 4ml/gallon)
Day 7
Bio-Grow: 1lm/l (about 4ml/gallon)
Bio-Bloom: 1lm/l (about 4ml/gallon)
Day 11
Bio-Grow: 1lm/l (about 4ml/gallon)
Bio-Bloom: 1lm/l (about 4ml/gallon)
Day 14
Bio-Grow: 1lm/l (about 4ml/gallon)
Bio-Bloom: 2lm/l (about 8ml/gallon)
Day 20
Bio-Grow: 1lm/l (about 4ml/gallon)
Bio-Bloom: 2lm/l (about 8ml/gallon)
Day 25
Bio-Grow: 0.5lm/l (about 2ml/gallon)
Bio-Bloom: 2lm/l (about 8ml/gallon)
Day 30
Bio-Grow: 0.5lm/l (about 2ml/gallon)
Bio-Bloom: 3lm/l (about 12ml/gallon)
Day 34
Bio-Grow: 0.5lm/l (about 2ml/gallon)
Bio-Bloom: 4lm/l (about 16ml/gallon)
I tried to give as much info as possible. That's my third project and I never had so many problems...
Please, help. I really want to finish these Kali Mists successfully. Thanks![Smile :) :)](/styles/smilies/icon_smile.gif)
P.S. I came to a conclusion that the yellowing is caused by Potassium deficiency. Here is why:

What do you think?
If that's the case, should I start with the Green Sensation (NPK 0-9-10) on full dosage? How should I combine it with the Bio-Bloom?
Thanks again![Smile :) :)](/styles/smilies/icon_smile.gif)
