Grow #2 - Indoor hydro tent

[Nate_in_AK]

Well, heck.

I'm not sure WTF is happening.

Fan leaves are rapidly drying out and dying. They literally turned crispy and will crumble.

Temperatures are 70-80F daytime, 66-75F at night. Humidity at 50-60% Humidifier is completely off, yet the humidity remains high.

Reservoir readings continue to puzzle me, consistently drifting downward. pH and PPM were low today, so I added more nutrients. I've been keeping PPM below 600, after thinking perhaps the had been previously over-fed.

Smaller bud sites look less scary:

I know fan leaf discoloration can be normal near the end of the flowering cycle, but this is only week 6... I guess it feels too soon, and also a bit sudden. These symptoms all manifested in the past few days.

@Aqua Man , @One drop -- if you would be kind enough to offer some advice, please?

Doing my best not to freak out.

Hi Nate I can see leaf tips burnt which is a sign of over feeding , I’m not a dw grower so that’s about my level of help im sorry mate I’d be dropping it down to 300 to 400 see if any change . Regards Od

Black thumb syndrome, man.

Swapped 75% of the res water. No nutrients added. pH @ 6.0 (ish) and PPM @ 400.

The symptoms seem to match Potassium deficiency, so if things keep going south, that will be my next step, assuming they don't die off completely.

They ain't dead yet....

pH raised slightly over the night (6.0 to 6.2) and PPM dropped a bit (400 to 350) and water level dropped about 1 gallon.

They don't look any WORSE, so I'm going to slowly work on getting pH down and keep PPM at 400 range.

This stuff looks like is was grown by Oscar the Grouch in his trashcan house.

 

[Nate_in_AK]

Very little change...

pH drifted down to 5.6, raised it back to 6.2. PPM is 350 today. I added a small amount of nutrients yesterday the PPM had dropped to 200. Water consumption remains about 1 gallon / day. This has turned out to be one ugly plant!! As long as she keeps drinking and the buds don't dry up like the leaves, I'll give her time. 3 weeks of flower time left, supposedly. Wondering if I should just clip all those leaves off at this point....????

Not trying to muddy the water friend but to my eye it looks more like phosphorus than potassium, you might want to check this out, best wishes

You notice blue-green leaves, slow bud growth, curling leaf. This may be phosphorus deficiency with your cannabis plants.Find Ways to fix the issue fast!

I believe you are correct, thanks for the post. I had looked at several and obviously confused my "P"s.

 

[Nate_in_AK]

Added 10ml "Growth Science Nutrients" B mix, which contains the Phosphorus if I am reading it properly. Small add, but I'm scared of triggering another wilting event.....

 

[Nate_in_AK]

5.9 / 350PPM this morning. Trimmed away the ugliest of the damaged leaves and added another 10ml of B mix.

This is week 8.
She's still ugly, but still growing...

Blueberry is starting to show some cloudy trichomes, I haven't looked at WW under the scope yet.

 

[Nate_in_AK]

Things got a bit hectic here. Harvested on Nov 30th. Hung dry for 1 week @ 50-60% humidity. I think this was either too long or too low humidity because the bud is a bid dry. Nice and sticky, but also crumbly?

Blueberry is the far right jar. I estimate 2 oz. total between both strains. Haven't sampled the Blueberry yet, but the White Widow is superb with excellent flavor. I'm looking forward to seeing how it improves with some cure time.

Next grow is on deck, will post a new diary for that one soon.

PS - For anyone interested, I've been tracking my monetary investment in growing. Current cost per ounce is at $129 so far.
