At first: the leaves going up slightly, the new leaves seems fine.

Yes, 2-3 times a day. After adjusting ph is stable for couple of hours. But next day it’s again back around 7-8…
Did new reservoir yesterday, added only tripart at 25% strength. No encymes this time. Rockwool already removed, (it has natural ph of around 8, did prepared them before).
It feels like the jiffy’s got still saved the fckd ph waters from the beginning. That’s the only way I can explain, why the ph climb up after a day.
Or is it just normal, the ph rises every day that much? O.o
Have air pump and 2 air stones in it making bubbles, would be no bubbleponic otherwise..
Actually no thermometer for the reservoir (already on my shopping list) (water feels cold, would say something around 15-18°?)
Have aluminum foil on topf of reservoir to reflect the direct heat of lamp.

Maybe I should just keep going, until all the ph leftovers in the system stable? (Sure flushed all the stuff except the jiffy’s, they was dry..)

Did started germinate 3 seeds in soil.
I just started and want to learn and get experience =)
Maybe I will start an new topic about my grow..

Following some photos:

€dit: can’t post photos in comment, will post them in an new post :]

Are you checking and adjusting your pH down daily?

I don't bother with a hydroguard or similar using aeroponics but change over the reservoir and givevit a rinse out every week.

I don't use Rockwell, it does have a natural pH quite some way away from where you want it, can't remember if it really low or high, I think low.

are you aerating the mix and what temps is the mix sitting at

Hello, I started my first grow.
hydro, 400w, did follow the Bubbleponics guide by nebula.
these are 2 week old clones, it’s more of an prototype run, get experience and started into growing =)

my question just: how long does the plants needs, till leaves not droopy anymore?


had catastrophic failure with ph at day 3, after checking found the Rockwool soaked/filtered some of the ph-up stuff somehow. This caused the ph rise over time. (Rockwool was ph‘ed before starting)
Removed the rockwool blocks, made fresh reservoir. Ph stable for now. Seen nice white roots coming (no pics, don’t wanted loose time).

Can it be overwatering too? I did setup like in bubbleponics guide. Watering is permanent, right? The pipes are below jiffy’s. The jiffy’s feels dry at top.

are there known issues of using TriPart Flora Series by Terra Aquatica, Advanced Natural Power (Enzymes) by Advanced Hydro and ph-up(+down) from Biobizz?
hardly wanted the original hydroguard, but hard to get in Germany/Europe…
just puzzled, how this can happen in the Rockwool cubes…

some pics following


edit1: leaves going up slightly

Do you check your PH before watering?

[Bluey]

I don't think so. Yours looks like an unusual nute burn...the colours are off but it could just be the pics.

Have you got any yellowing in the margins? That with brown edges is often potassium deficiency but I don't see that.

How much nute are you giving it and how often?

Check the pH too

Is my issue the same as yours?

[Eclipce]

Hey everyone, Upper leaves are drying and burning, not sure what's wrong, tried changing temperature, moving the light, adjusting humidity, flushed the pots two days ago just in case but don’t know if it’ll help, haven’t added Cal-Mag yet, is this a calcium/magnesium deficiency or still nutrient burn? Should I remove the damaged leaves? Soil Biobizz Light Mix, nutrients Advanced Nutrients pH Perfect. Day 73 of flowering.

[Rootsruler]

Your plant is going into deficiency. It looks like a calcium/magnesium deficiency but without know more about what you are feeding the plant, what media type you are using, etc, it's hard to say but cal/mag deficiencies are common with these plants. Do you have some prepared calcium/magnesium solution to supplement the plant. Epsom Salt will work in a pinch if you don't.

From the looks of it you are in week 3 of flower?

Please help me. Why are my plant leaves changing color? Is my plant dying?

Bluey and Gingerbeard!
Many thanks for your advice. I'll keep the dome for a few days and watch carefully what happens. I've also ordered a cheap humidifier which will arrive early next week.

[Bluey]

Yes it will help a bit but what happens very fast is they grow tall and lanky without a breeze pushing on them, so it's a compromise.

Maybe giving the soil a flush would be best but I've never grown with that soil so not sure. The burn doesn't look terribly bad and was hoping as the plant matures over the next couple of weeks it will adjust and then explode.

Yeah, 55% much better than 42% but still not where you want it. That's pretty typical of the wet towel approach.

[Gingerbeard]

Perfect. Make sure the plant doesn't touch the sides.
Let's talk about this for a sec. I don't dome so I don't know. Turn the bottle into a sort of chimney by cutting a couple dime-size holes in opposite sides. Will this help with humidity while still allowing air flow?

[420RPM]

I made a dome from coke bottle just before i went to work. I hope it will work and doesn't get too hot for my little girl. The wet towel and a fan only raised humidity to 55%.
