Quick advice please. Let's save my plants !

[Dr.Moggs]

Hello everybody !
I hope I can get some quick advice on the problems my plants are showing.
I last visited my plants like 6 days ago and everything was going really well. Now when I visit them I panic. It doesn't look good at all but i hope i can save as much as possible.

so, 6 days ago I found some stains. Noting to serious back then.

Problem 1.
now I have hard cupperstains on two plants. But I can also see that the are spreading to other plants.

2.
My biggest plant had grown in to mine light and was only about 10 cm from the lights. The leaf now look burned and the lower budsites are losing life.

I know that it's natural for the leaves to yellowing in the end of the lifcycle but I believe this to be something else.

growing in hydro.
nutrients from goldlabel
ph: 6.4 (lover it now)
EC 2300.
week 7 flower

[Dr.Moggs]

I would like to cut of my main budsite on the biggest plant. Can I do this or will it stress them to much ?

It is already damaged and will give a lot of light to other budsites that it shadows today.

[Potted]

Heat damage for shore. Unless it’s controlled the party’s over

[Campesino]

Well, you aren't going to have good success with an indoor grow if you are abandoning your plants for a week at a time!

Starting to think the "cupperstains" may be something like Tobacco Mosaic virus, but can't tell. Looks like bad heat and light damage, but they may recover. You are going to have to start applying more TLC! The plants have a long way to go if they are going to make it!

[Dr.Moggs]

Campesino This was the first time leaving them unsight for that long,
Otherwise I visit every day.

What is TLC?
I understand that I probably have to do something drastic for the overall good... do you suggest I either cut the sick parts of, throw the whole plant or try to treat them ?

[Campesino]

TLC = Tender Loving Care

Tough to say. Some are pretty badly damaged. I would try to save them, but maybe have to cut away parts that are really gone. Need to get the climate right and make sure they have water, etc. Set the lights properly and hope they recover.

[Dr.Moggs]

Word ! Lessons learned, I'll never leave them that long again.

The buds on the most stained leaves still looks healty.

but if I cut the budsite on the main coala, the burnt one. How should I cut it ?

[Campesino]

With scissors or snips!
Cut the stem above a good bud site/flower cluster.
Only do this if you are sure the top is gone.

[Dr.Moggs]

I cutted It below all that looked screwed.
now I will move the remaining budsites in order.

regarding the stained leafs, I'll let them be for now and hope that they survive rest survive.
I'll keep my average temperature lower and will buy some better fans than the 12 v fans I have today.

[Campesino]

OK, just wanted to make sure, because it certainly looks like it got hot in there!

If it was just a one time issue and you can control it now, they should be able to at least mostly recover.

[Campesino]

Dr.Moggs
Just noticed that your EC is 2300. It will help the plants recover if you lower that for a while. They need to be able to get water to recover and high EC makes that difficult. I'd drop EC to 1800 until they recover.

[Dr.Moggs]

2300 is the highest i have been and i have been on that level about 3 weeks.
I'll replace some water to make the EC go down.

[Sheesh]

I would try adding Cal-Mag and lowering your ph to 5.8 to 6.0. What are your tent and water temps?

[Dr.Moggs]

The tents are maximum 29 ° but i try to keep them at 28 but on hot days it go up to 29.
The water I keep between 22-24 °

I am feeding them some cal-mag with spray bottle on the leaf. I have also added some extra to my water reservoir.

[Sheesh]

Sounds like borderline temps in the tent and water but should be OK if you have good airflow. Make sure you have no light leaks for your roots too. Cal-Mag is important for hydro and coco grows IME. I would suggest adding 2-5 ml per gallon for the rest of the grow and lower ph to 5.8 or so. Are you using Hydroguard?

[Dr.Moggs]

I'll keep my water and room temp under control now when I'm back from my leave.
I am not using hydroguard, the only thing I use for my roots are Enxymes and the roots haven't amhad any problems earlier.
