Ok from obvious signs it looks like a potassium deficiency..

This started happning about a week ago when I changed my nutrients from House and Garden Aqua Flakes to Earth Juice Organics...

The earth juice threw the PH way off so I was constantly having to add PH down. (I noticed Potassium deficiency can happen because of too much salinity).

2 days ago I decided to switch back to house and garden because I couldn't find anyway to stablize the PH without adding so much PH UP/Down. (I mean it was all over the place. One time I'd check it it was like 4.0 I'd go back a few hours later it would be at 8.0). The hydrostore guy warned me of this. Dur.


(Ahh after writing this I've realized its ph UP that causes this. But I haven't used any PH up.) Only down.

Everything else should be fine.
Temps 72 Night 78Light
Air stone
PH flucuates from 5.5 to around 6.8
400 watt HPS about 15 inchs from the plants. (3). All are showing these signs.


Im guessing it has to be the Earth Juice bloom that I've added. (Along with the baseline nutrient of Aqua Flakes A & B I'm using about 4/5 of the recommended serving for earth juice bloom).

Halp

hey skunk thanks for the info. I've checked on nitrogen deficiencies and it sure looks like it. How could this happen even though I've stilll been using strong grow nutrients?

my guess is that when you switched to bloom they are lacking a bit of what they have been used too. If adding N doesn't help there are diagnostics you can run. I have an app on my Droid cleverly named grow app
