new pics finally...all comments welcome

I remember the other night when you were asking about ppm, after you got your truncheon meter...I thought your nutes were too strong...I think I mentioned it in the thread...goodluck, post some more pix.later H2o2 works great in that situation...went thru same thing, not as bad, a few weeks ago...remember to err on the side of lighter nutes, and you will have a safer grow...imho

Still third week added plain RO water to dilute nute strength...Per advise from people here..I am going to be getting H2o2 end of this week ...How much should I add and is it safe for the plants....I heard that it kills all the bad and good microbes..Any suggestion please....still look healthy except couple of fanleaves on one of the plants had to cut off nute burn....live and learn....Temp got real hot in room yest...even know I have a 5,000 btu air cond.. running full time...Lights go off at 12 noon and resume at 6.00 pm...starting today to try and keep room under 80deg. At night temp goes down to 70 deg with 1000 watt hps light on...I will not be adding Gro the next nute change only micro and bloom calmagplus and diamond nector,,,,With H2O2??????and another bubble wand since roots are getting so long...I felt roots and are not slimy or crumbly.... LOC and Latewood/ any more sugg????? Zandor the great???? no pics of roots yet tommorow will be posting

I use liquid karma in my grows and the roots always have an off white color to them. I have also had root disease. The roots get really brown and stop growing showing none of the fuzziness your roots show. After looking at the picture the lighting may be somewhat different on the roots in the back of the tub.

As far as nutrients go you didn't mention what the ppm was. The stage your plants are in I usually try to keep the ppm to about 300-400. You can always go up, but it may be too late to go down when there is too much. Why cut off their nitrogen when that is what they want in veg stage?

Also, can you give me some info on that white pvc manifold with sprayers. I like that setup.

Airstone baby... airstones!!!!!!!!

SUPER safe route.... air stones : )

[latewood]

even in a res w/sprayers, you need bubble stones unless you are constantly recirculating....
OK, daddy...H2o2 cannot be used with organics...I haven't looked up diamond and calmag + so I don't know if they are chem or org, but I used to put 45-90ml tbsp to 10 gallons...do the math and I haven't ever really read where anybody claimed to damage their schtuff using it, but I'm sure there is a Tolerance level...there is a growgfaq somewhere...
Real glad your roots are OK and I think the light had a little effect on the odd coloration we saw...later

What is the purpose of H202 in hydroponic growing ? Clean the roots ? That's right?

I used 1/2 in. sched 40 pvc with 5 tees one tee for the piece from fountain pump to line. and four for the drip heads Cut pieces of 1/2 pcv to connect the tees...all pvc and fountain pump is from LOWES...1/4 in black tubing and drip heads and micro sprayers from Walmart...cut pieces of 1/4 in tubing about 1 inch to connect the micro sprayers to the drip heads...also used sched 40 threaded adapters to connect the tees to the drip heads
1/2 in tees=40cents
5 ft 1/2 sched 40= 1.49
drip heads=4x 6.99
1/4 tubing=4.00
two threaded sched 40 1/2in end caps=20 cents each
370 gallons per hour fountain pump=49.99
sterelite 30 gallon container with lid= 8.99 from lowes
pretty cheap compared to some aero systems out there!!!

the 1000 watt hps light cost the most

I have to agree with Garden Knowm add an air pump with stones to that resevoir if you don't already have that. The more dissolved oxygen you can get in the resevoir the better the plant roots will take up nutrients. The oxygen is just as important to the root zone and plant health as ph and ppm.

Thanks for the info on your set up.
