Having more problems 5th week.

my plants just recovered now it’s this...

Looks like you have some light leaking into the rez, and looks a little nute burnt but I couldn't say which one. What strength are you running the nutes at?
Also check the stickies in this forum, lots of good info

Well I did change the water in my reservoir sun. They hadnt had nutes over a week cuz of what I thought was Nute burn.i just put some today. But I only used 1/8 of a cup. Maybe a lil less

Is PH in range? 5.5 is a good target but fluctuation is fine. Out of range and you get lockout on some nutes, or so i have read since im on my first grow lol. Do a Google search for "nutrient deficiency marujuana" and a bunch of useful pictures come up to compare with

Buddy,

I am not a hydro grower nor an expert but careful with these roots colour, that brownish tint to it is not really a good sign - Might be light leak like somebody is suggesting.

Happened to me once in soil, and had to wash them with a mixture of hydrogen peroxide and repot.

Good luck!

Oh has been fluctuating like crazy but everyday I use ph up or down to correct ph.

What's the set up?
System, water temp, res size?
How does the water get oxygenated?
What are they been fed?

It has a bubbler. I guess the resovoir about a quart size. 150 wat led light. It has an air stone. They sent me a powder nutrients

Do you use liquid oxygen
And h202 in the tank and are you letting the ph down mix before the plants get on it otherwise they end up drinking straight acid I’d also have a pump mixing it all around but that’s just me roots don’t look healthy

You using hydro guard?

Just started using a lol hydrogen peroxide yesterday. And I order Hydroguard yesterday too

Root issue for starters; they should be bright white, not brown. I would check your reservoir temperatures, confirm your pH is stable through out the life of the nutrients from reservoir change to reservoir change and I'd disinfect your equipment as well as mix up a new reservoir's worth of solution. Bright white roots are your friends, coupled with a reset of your system and you'll be in good shape.

My one health plants are now getting these spots. The other still look curled up and droopy. Reservoir temp was 73. I’m bet it’s prolly hotter during the day. Also is all this root problems???

I don't have practical experience in your type of grow, but I'd research the ideal reservoir temperature. It's been my experience, through reading, that your reservoir temperatures are super critical for healthy plant growth, including roots, when working with your type of growing method. As to if all your problems stem around the roots; I can't comment on that. I would simply try to eliminate the variables; assure your pH and assure your reservoir temperatures. Once you have those handled, eliminate the next variable and so forth.

buy some liquid nutes,havent used powdered nutes for almost 20 years.ph shouldnt be fluctuating that much,change nutes with fresh water and see !!
