Dropping Leaves on Tomatoes
New to hydroponics and this is my first grow. I put this tomato plant in the grow chamber about three weeks ago.
Its been growing nicely until today.
About 4 days ago, this Dutch Bucket had a drain problem and
flooded. I replanted it in another dutch bucket with fresh
Coco Coir and Pealite within an hour.
Yesterday, these leaves looked fine. Today they are wilted.
Please see photos.
I've gone through your checklist:
1) Temperature fine - I have an exhaust fan that comes on at
80 degrees. During lighting hours it keeps the temp between
78 and 80. It comes on to exhaust air from the top of the
chamber every five minutes and runs for 2 minutes.
2) I'm not sure about the relative humidity. I'm getting a
sensor now. But, the relative humidity in the house is
very low, about 25 percent. Its winter and the heating
system is forced air. That's the air that's being pulled
in by the exhaust fan.
3) I think the air exchange into the grow chamber is fine.
I don't have a fan blowing on the plants. I only have two
small plants at the moment. I'm having trouble finding
a suitable fan. I'm probably being too picky.
4) I am using LED lights. I don't know if they will work
for the flowering and fruiting stages, but this early
growth stage they should be fine.
5) Light height. The plant had grown so it was closer than
12 inches, but these are LED lights. The back of my hand
did not feel too hot. Also, wouldn't it scortch the upper
leaves before the bottom leaves?
6) Reservoir temp is 70 degrees.
7) I have 30 gallons of solution. I'm using your suggested
method of replacing half the starting solution then letting
it drain down to the pump. I've only added 5 gallons water
8) Feeding or watering problem. Media is 50/50
Coco/Pearlite. I feed every 12 hours for 15 minutes.
I'm using drip rings instead of stakes. Drainage seems
good. I hear water trickling into the reservoir within
2 minutes of the pump coming on. I was concerned that
since this was recently replanted and the rings are
about 4 inches in diameter, maybe the nutrient solution
wasn't getting to the roots. I put a couple of turkey
basters of nutrient directly at its base about four hours
ago and the leaves look worse.
Any help would be appreciated.
