Everything had been going really well until about 6 days ago when I detected some stains, they came probably from an PH issue. I had been away from my plants for 6 days ( day I detected the stains) and came back to what I first saw as an disaster. After receiving some advice from here and working with the plants I still have hope to make them deliver some nice buds.
During my leave I have had high temperatures in the tents and the PH have been out of zone.

Lessons learned, you can't leave your babies alone that long 🙄

Setup 1 is in Week 6 Flowering.
PH - 5.8-6.2
Watertemptrature: 23-24 °
Tent temperature: Max 28.5
Tent humidity: 40-60%

"Setup 1." Is the one with two tents:

One with ScrOG net:
This tent still looks really healty, I have some minor stains on some of the plants in the ScrOG but I think they will recover now that I am back.

One with an soft big hole supportnet.
HERE ARE THE REAL DAMAGE.

1. My biggest plant had grown almost all the way in to the light? About 10 cm from the light and combined with the high temperatures been burned. I cutted of my main coala about 25 from the top-bud. After cutting it I taped it.
I also bent the other high budsites to get them down.
(Lession: start training my plants earlier to maintain an even canopy.)

2. Two of my plants have seourios cupperstains and some other have some minor stains of the same kind.
The two plants with the worst damage is also the one I detected the stains on first. I have received ideas for the reason of the stains as:
Ph Issue.
Heat Issue.
Cal-Mag diffency
Tobacco Mosaic Virus

In this issue I would really appreciate some advice.

Setup 2:
This is my smaller tent with the drip system.
PH - 5.2-5.6.
Tent temperature: Max 28°
Tent humidify: 50 %
The plants are in beginning of week 4 veg. I have topped all of the plants and I can see the new coala coming out on all of them.
I am thinking about introducing my plants to a ScrOG in the end of the week, but until then I will let them grow.

Is it common that plants grow in such different speed ? It was the same in with the two other tents. I believe they have the same conditions...

The plants that are in flower now I only had in veg for 3 weeks, I'm thinking about having these in at least 5 weeks.
In this tent I would appreciate some input on how to best prepare my plants for the ScrOG....
What can I do about them growing in such a different speed?
When should I switch to bloom?

This is my first hydroponic grow and it's amazing how quick things happens and how quick it can go from really great to scary stains and burned leafs.

I hope I got most of it covered, ask if you wonder anything.

Happy growing!
 
OK, well then consider lock-out as the cause, because you are giving Phosphoroous - but it can get locked out. May be all related to pH
 
Do you have a water chiller? Those temps are WAY to high unless you’re running a chiller. If your taking temps from a main reservoir that is located outside the tent they will be inaccurate to the temps in your buckets at your root zone. I would love to see your root health to see what’s going on under the hood. Roots will tell you a lot in DWC. Other than that your readings seemed fine.

Unless you have a digital PH monitor AND doser as well as some form of nutrient solution temperature control, you cannot leave a hydroponic system unmonitored. So many things happen when temps change and ph is wrong and because it’s hydro those problems will effect your plant within hours let alone days! Then those problems are amplified exponentially the longer the problem is not resolved.

Hydro is very sensitive but they also bounce back quickly. Unfortunately I’d say those girls in flower are irreversible but you can limp them to harvest. I’m not even going to address nutrients and ratios because I don’t believe nutrients are really the problem. You may have had a deficiency or some kind of lockout like the other guys were saying but after the 6 day absence it’s irrelevant.

Get back on your feed schedule. Get your temps and ph back to cherry and then address problems that continue to worsen. Check your roots, CHANGE THE RESERVOIR ASAP, and get back to somewhat of a “fresh start”.

Never leave your system unattended ever again. If you’re someone who requires to travel and you’re still set on a DWC hydro setup you will need to invest near 1000 dollars in some digital monitoring and dosing equipment as well as a water thermometer outlet monitoring your water temps and turning on your chiller whenever needed. THEN you’ll still need a trusted buddy to do a reservoir change if you’re planning on being away longer than a week.

I’m pro hydro and run DWC as well so don’t get discouraged, But you have to be committed to the daily checks if you want premium hydro buds!
 
In addition to my previous reply. If this is your first run with any kind of hydro I would change nutrients to something much simpler to mix. Find a premixed nutrient, I love Botanicare pro blend grow/flower for my base. Then I’ll add micros and whatever specific nutrients I want for the specific crop. Much easier and simpler for the first timer. Then once you get good you can play with exact ratios. It’s also a whole lotta work!!!
 
I feel like after 6 Days away there isn't a real reson to speculate where stains and burns comes from. I rather just get all my values on point again and see how they progress from now.
I just want to make it to harvest with my first grow. 😁
 
Hey Dude and thanks for your replay.

I dont have any waterchiller today but this is something I thi k about investing in in the start of next grow.
I can upload a picture of the roots later, when I checked yesterday they were looking healty, no slime and no smell.
But I didnt look at the roots on the sick plants so I'll upload pics on the sic and on the ones still looking healty.

Lessons learned, I can't leave them for that long again. Not without babysitter or fully automatic hydrosystem.

The reservoar is changed an EC lowerd to about 1900 from 2300 to help them recover.

I regret leaving them unattended like this, everything was looking so well.
 
I didn't want to go with Gold label from the beginning. But where I live it's hard to find nutrients. Goldlabel however is easy to find to a good price.

I am pretty handy and pretty smart so I think I can manage the nutes, i just can't leave my plants this long.
 
Live and learn brotha. I have to say you’re doing everything right to rectify the oops! And yes I’d suggest a water chiller even if you feel your temps are okay. They’re indispensable in a hydro system and really help create fire crip. I’m confident if you’re confident with the nutrients. In no way meant you were incompetent. I just feel it’s easier. But you’re a step ahead if you can master nutrient ratios to that degree. Happy to help and can’t wait to see those roots! Really looking forward to continuing the conversation!!

Much Aloha!
 
Try amazon, or local grow stores. I know you said there isn’t a whole lot where you live but many places will provide free shipping within state so if you could find something like that they’d be delivered to your door.

You think you’ve got it bad!? I had to fly to Big Island for some Hydroguard!😂😂

NebulaHaze I take your suggestions with weight. Couldn’t get Hydroguard, SM90, or great white roots shipped to island and the hydro store was 2+ months out on both hydro&sm90

Made a point to stop by Ohana Greenhouse Supply on Big Island and bought 3 gallons before heading home!
 
[ First update ]
So far I can't se any more bad signs on my plants, I rather think they look a bit happier today.
I'll post some pictures of my roots, IslandColas

These pictures are from the sick plants and one is from the healty ones.

Here is two better pictures of my staind leafs.
20180611_195516.jpg20180611_195541.jpg

I bought two table fans today that I will place in the bottom of my tents, I haven't had any fans under the leafs and I think this will help to keep the air fresh and in right temperature.

Any thoughts ?

I Believe the stains on the leafs are the aftermath from ph-issues. My Ultra PK is the chemical I use to regulate phosphor: "The Ultra PK formula prevents phosphorus from depositing at pH levels>6.2, promotes availability of Ca, Mg and trace elements"
 
I'll Think about getting a waterchiller, today im using the oldschool method. An an big 5 L can of ice in the main reservoir to keep the water from becoming to warm.
No worrys , I just have an issue with limited access to nutrients.
From the start I wanted to use Genral hydroponics flora gro and flora bloom, have you tried this series ?
I have read a lot of good things about General Hydroponics.
What nutrientbrand do you think is the best ?

Aloha!
 
Gotta love your dedication for your plants, flying to get nutes. Impressive ! 😅
Since my roots seems to stay healty I'll keep doing what I'm doing, when I change nutrientbrand I'll find a new way to stay on top with the roots.
