Had to name the post wankers because no-one on here really tends to reply or want to help, i have posted this thread in plant problems with NO REPLY
So im trying my luck here!

Running a iws system
Amnesia haze
Hydrotops nutes
(100% organic)
Res gets emptied and refill every week
Res is outside room and stays cool
Using bactivator (root protection against pythium etc)
Using root stim and
Everything i should be using!
(Done this on previous crop with no problems, i havent done anything different)

Few weeks ago the roots turned brown and shrivelled up but the plants continue to grow
No obvious signs of anything to worry about
Plants was still growing fine
No changes on the leaves or anything

Today i go in and some of the leaves mid plant look like this!
Can anyone help me?

Also how old is the plant? Still in veg?

Leaf pic looks like calcium deficiency from my limited knowledge... but!!! if your roots are fucked then that can look like you have any deficiency going.

You're in DWC and you say you have brown roots. My money is on root rot.

What made you choose organic nutes in DWC?

Organic nutes and true water based hydroponic system is tough. Go to real mineral salts. Ive actually never seen a successful deep water culture system using 100% organic nunutrients. If we growers could get away with growing directly in a bubbling bucket of tea (which basically sounds like what your doing) we would of been doing it a long time ago. Never worked for me. Go back to mineral salts. Pay attention to pH and EC. Lots of dissolved oxygen. Bet it clears rite up. 99% of the problems ive evr encountered or seen in other growers water based hydroponic systems has been nutrient solution temps being too high. Very little margin for error with these systems. And with organic nutes on top of it...nope.

I run organic, botanicare PBP in dwc and an aero/nft hybrid. Res temps as high as 76, averages around 70F, no issues. Proper aeration and keeping a healthy, beneficial bacterial colony going is all it takes. I run Hydroguard. I've also noticed most people that have root issues don't keep their res's clean enough, I see dead leaves, roots, hair, etc, etc. There needs to a minimum amount of dead material allowed in the res or the beneficial bacteria won't be able to process it fast enough, which leaves food for bad pathogens to take hold. I have a small aquarium fish net I use to skim and clean my res's of debris.

Pure blend pro is not all organic. But its damn close for what it does. Ive used it. Its decent. Jist never in anything besides peat mixes.

I know of several HT in the dam winners who ran the G&H organic grow box and WON cups with it!
It can be done - see the next section of my answer. (see, Wfreak does it!)

CLEAN! YAH BABY!
So what do you give the bbc to colonize on? Just interested as there should be something for the ones (strains) that don't colonize the roots - right?

I found that synth or organic....There are MM strains that simply don't like 70F roots in hydro, any hydro......I always kept my res temps below 70! just to be safe....nothing more frustrating then loosing a big portion of your run to teach you that one..

I suspect OP, that the discoloring of the leaves maybe related to one or more of the nutrients used. As long as they don't get "slimy and mushy" and the plants growing! So what!

The pH is suspect and it could be dropping too much and doing some cockblocking of nutrients.....first choice.

Next would be add some organic Ca/Mg....3-5 days and the new growth should look healthy. The lower leaves should stop showing progression of the problem and will not go back to looking "normal". Only N issues "recover" normal healthy looks to leaves.

I don't feed anything specific for the bennies, just whatever residual wastes/excesses are in the nutes. No point in putting in additional bacterial food sources.

To the OP, looks like PH issues. Could be caused by numerous things.

Nope, mistake in translation - lol.

There are bacteria that "inhabit/live on/colonize" the roots....Many others do not! They need somewhere else to "colonize" and live....Some add a filter pad or a handful of hydroton in the plants pot bottom. Others run the tank through a filter pad for that holds the "colony"...


Not feed them!


Understand now ;-);-) 8) ?


I agree = pH issue!

Ph and ec are fine

Res is always clean mate, gets emptied and re-filled every week!
