how long until i see corrections in dwc?
i think i had a low oxygen issue

root rot, with the hps on they look white but roots are brownSounds like you answered your question if they perked right up.
Roots are not growing but they are white? How big are the plants and the root balls? Pics?
I am assuming these plants are already quite big if you were to legitimately have low oxygen levels. Is the root ball getting adequate flow through it? Its possible if the root ball is big the inner portion is stagnant and thus not getting oxygen in which flow would be the problem but can also be solved with extra movement from more airstones.
Pics would really help. Root and foliage.
I am no expert and yet to grow MJ but have dealt with water parameters for 20 years in regard to aquatic plants and flow is often an issue.
There ya go so now you just need to figure out what caused it. Maybe flow issue? Idk your parameters look good and at 67 water you should have decent o2 levels even with slightly low air volume input because the further o2 levels go below equalibrium the faster that gas exchanges. Again I have no idea of size of plants or root system. With hydrogaurd if used properly it's unlikely bacteria is the root cause.root rot, with the hps on they look white but roots are brown
water temp is 67 and i use hydroguard
changed water 2 weeks ago, my rez is very large so ec and ph rarely move, no dechlorinator but i used to use primeLooks like root rot and lockout to me, maybe at some point nute burn? Idk. How often do you do water changes and do you use a dechlorinator?
Your probably going to need someone with more experience than me to help you fix this. Maybe @heisenbubble can lead you from here if he doesn't mind.
Did these issues start around then or within a week after? Thinking clorine might be the initial culprit and yes I think 1-2 inches below the pot for water level like @chemistry said is a also a good place to start.changed water 2 weeks ago, my rez is very large so ec and ph rarely move, no dechlorinator but i used to use prime
i think i should wait a few more days then to drop water level, dont want to make too many changes, i just added the pumps on saturdayIs your pot sitting in the water, if so, drop your water to an inch below your pot and see if it clears up. A week is what I find normal for changes with my setup in DWC.
Will also help lowering water level to get circulation through the roots a bit better once they are biggeri think i should wait a few more days then to drop water level, dont want to make too many changes, i just added the pumps on saturday
700 gallonsMost important question how many gallons and how many watts of air pumps you running?how many buckets or totes and how many air stones total
thats my personality type(overkill) plus i wanted to eliminate any doubtJust my thinking but I dont think 500 watts was bad and 1200 would be overkill. Curious to see what heisenbubble think on this. I know ppl think 1watt per gallon but I think that's overkill personally.
Air is like calmag,better to have more than not enough.hard to overdose it.Just my thinking but I dont think 500 watts was bad and 1200 would be overkill. Curious to see what heisenbubble think on this. I know ppl think 1watt per gallon but I think that's overkill personally.
yes, its me. trying to make this system work, i added more air and covered top with visqueen plastic and added an exhaustAir is like calmag,better to have more than not enough.hard to overdose it.
I feel like I remember this thread a while back and the guy kinda fell off.
