I had the same issues with deficiencies and suffering plants. I've had roots aphids before and when I experienced the similar problems again I figured it was RA's. I then treated the plants with merit75 and nothing changed. I grabbed my microscope and took some pics... I never was able to find...

Hey UCHQ, I've got a thread in the infirmary My question to you is: If my ppm is dropping is there a chance that I'm still overfeeding? My ph is rising and my ppm is dropping and I'm getting what looks like the claw. Also, some of my leaves mid plant look like they may have a cal mag...

For some reason I was thinking I may be low on Cal mag, as I'm using RO water. I'm gonna flush and give them some lower nutes and see what happens for now.

Upon closer inspection, three plants are worse then the others. These three plants are from the same mother plant, the remaining plants with very slight clawing are from another mother, all plants are the same strain G13. My water levels have remained about 1-1.5 inches below the net pot...

Hey jagle, just checked my meters, and they are all good, all thermostats and humidity sensors are at canopy level

Thats whats so puzzling to me, my ph is rising and my ppm's are dropping. I'm going to dilute the nutes a bit for now until I get some more feedback thanks for the help

Something is definately off. I have lots of air circulation, and I'll go check on my meters again, recalibrate I was also thinking the nutes were too strong, but wouldnt the ppm rise if I was going too hot on the nutes?

eh Big Sky, Air pump is located outside of the room, Roots are looking good and nute temps are around 67-68

Room temps are about 78-79 lights on, 70 lights off Humidity 50-60% CO2 1000ppm

Hi everybody, I have a RDWC under current system up and running, trying it out. I'm about week two into flowering. My nutrients are at about 700 ppm and ph around 5.7. My ppm drops every night by 20-40 ppm and my ph is rising everyday by .1 to .4 I use RO water and Canna Aqua nutes, cal...

Hi Ben! I look forward seeing round 2 I tested a oxy-gen unit earlier this year for a couple runs and found it to work quite well.

Just bumping this thread due to the fact that I had to play "firefighter" last week due to one of these catching fire and taking out my grow. Seems that I missed all the recall notices posted online...damn

Enjoy your vacation! definately well deserved

My air pump is located outside the building bringing in fresh air. I have somewhat figured out the problem which was my water temps where a bit too high in the buckets and starving the plants of oxygen. I lowered the temp on my water chiller about five degrees which made it ok for the water...

That's what I was thinking but wasnt too sure. My water line is a bit high but at least I kept the cube quite high to make sure it doesnt sit in the water. Covering the top of the bucket I feel is a must as to make sure that the light stays out,

I'll be doing the big cleanup/rinse tomorrow. I'll pull the plants and dunk'em like you did..thanks for the advice!!

When I rub the roots they are brittle and do come apart :(, The lids are covered with one layer blackwhite poly and only layer of litetight plastic, so no light gets through.....I hope

I was just wondering what too high a water level up the bucket would do to the plant? I'm about 2'' to 2.5" from the bottom, though my plant sits very high in the bucket. Just curious as to the reasoning behind it

Ok, just got in and took some pics, hopefully they will bring some light to all this. Now take into account that I have B1 in the system as well as roots excelurator, which is why i thought my roots were slighly tan in color I have also failed to mention that over time pieces of roots appear...

All my plants have two layers of plastic that surround the top of the bucket with a hole for the stalk of the plant. I figured that would solve any light penetration issues as well as keeping the co2 out of the bucket though I'm sure there must be some vacuum in the bucket from the water wanting...
