Im getting the same problem!
sorry they are out of order:
1st pic: after a few days of spotting
2nd pic: after a week or so of spotting, they dry up and shrivel
3rd pic: early spotting, 1st day or so
4th pic: everything
my setup:
600Watt HPS - 30 inches from plants
DWC
plants are 24 days old, was on a 17/7 for first week and a half and then a 14/10 for the next week and a half, 23 days into it, switched to 12/12.
pH of water: 5.0-5.5
Nutes: 20-7-7
3 Fans to keep everything cool
oh yea, and I forgot to mention that this spotting is happening from the bottom up. Starts at the bottom leaves, and is working its way up.
I have tried flushing my water in my DWC system, halved the Nutes and raised the light 3 inches above and lowered the water level because of possible overwatering.
I think it might be nute overdose as I might have added too many nutes. What do you think it might have been? maybe we can solve it by looking at both of our commonalities.
And to make matters worse, I woke up to one of my fans sitting on top of my babies! so with slowed growth from whatever this problem was, and the fan breaking some leaves, I don't know what the solution might be.
The pH is at 5.5-6.0 somewhere inbetween (strips)
Temp shouldn't be a problem for in the water, don't have a measuring device.
don't have a ppm meter
the nutes I used were a 20-20-20 for orchids, I did 5 tsps in 5 gallons.
the lower leaves get affected first.
they tub is a 5 gallon DWC
from seed
no idea what strain, seem to be indica tho
32 inches from the top of the plant, 600 watt HPS
no humidity or temp gauge
yea, that might be it, my friend told me my plants are not getting enough oxygen because they look droopy.Quote:

Revanche, you are growing in a COMPLETELY different setup and your problem will be troubleshooted (? uhhh...) very differently. Please start your own thread next time.
Okay.
Your pH is too low.
You're using a completely wrong fertilizer for young cannabis, ESPECIALLY in hydroponics.
You have no way to check temperature.
You don't know your ppm- even worse because your fert is wrong to begin with.
You will either need to basically re-do your setup from scratch, following the basic DWC guidelines outlined in several grow logs (check the 'styles' thread stickied in basic), or consider switching to soil, which is more forgiving if you don't have the correct equipment.
lol I was wondering why these guys seemed to be talking to themselves lolQuote:

whats wrong with the nutes? 20-7-7? has micronutrients in them.
Your pretty much saying I need every whizz gadget and gizmo to run a decent setup? :\
lame.
