New Grower Mephisto Strawberry Nuggets, 4 Assed Monkey & Fantasmo Express x Sour Stomper

[davisgirl]

Hello all! Mind if I tag along? Always looking for new learning opportunities, and the Strawberry Nuggets are in my future! Whatever ails them, blame your girlfriend LOL.

Could they have had some water droplets left on the leaf while the light was on? I wouldn't worry about the spots, the cupping I would watch. Can you raise the lights a bit? How far away are they?

Hey, I'm under HPS not LED but the heat is pretty minimal and the light is only at 400w. I dunno... I've not experienced anything like this before. At this point I don't know what to do other than keep going as I am and hope for the best... As the new growth looks OK I guess I'll just keep on with low nutes and see how she gets on.
I actually don't have a PH meter but have been testing each feed/water before it goes in with liquid PH tester. Hopefully it was a PH error as that's easily corrected. I've done a bit of research on algae and I don't think it would cause this much of a problem and certainly not so quickly but there's not a lot of info on it other than specifically in DWC set ups.

I guess i could raise the light a little and see if that helps... it's driving me nuts!

Ah fair man I'm not sure why I had it in my head you used LED, oh well it happens when you're baked 50% of the time lol

But yeah man I know the feels, when my Blueberry had yellow spot that started spreading like wildfire it was kind of a frantic search through the net to diagnose but I got lucky when I saw something had gone and with the speed it spread it was obvious in the end.
This must be all the more frustrating.

Algae can be particularly devasting to a lot of plant seedlings but in photo I couldn't tell you what's caused the discouration and it may not even be algae

Either way I wish you the best of luck man, Im sure someone here can help

quick question before I chime in... I'm guessing that is a coco / perlite mix and at what ratio have you mixed it up?

Thanks @Slater It is indeed, it's about 70% coco 30% perlite.

I did think that, I thought i'd been careful about it though. If i see anything I dab it off with a little cotton wool and the way it looks to have spread does suggest it's down to something else. I will raise the lights a bit anyway, there's plenty of room to do so.

Please do, the more the merrier. I wouldn't have pulled off my last grow without her so I couldn't possibly! I doubt it's anything she did and i shouldn't think that anything she might have done would have showed so quickly. She pulled two plants though 10 days of early flower on her own so I have faith in her!

At a guess I would say your light may be too close which could be causing the curling of the leaves (heat stress)... the odd brown spot could be a calcium diff sign due to the light being to close but It doesn't look like to much to worry about.

Raise your light and keep an eye on all new growth. If you see more spots try upping your cal/mag a little

i agree with @Slater, even though the ambient temperature of the grow space may be one thing, the heat/light radiated directly from a light/heat source is a bit different. it’s quite easy to get a bit of heat/light stress on young plants especially with powerful HID and LED lights.

i’m pretty glad this prompted me to look back as in fact i had my current seedling raised to the light a little too early and you can see some minor cupping on the finger leaves (shown below) but as shes growing into the light the issue resolved itself but obviously i’m now wary since i realised i made the same mistake on all my seedlings and is likely partly why a few didn’t make it. doing more research into lighting now and i didn’t realise quite how complex it is! glad i didn’t brazenly employ sidelighting

p.s. looking at older pics of seedlings they also had similar brown spots on leaves affected by the light but no calmag problems here as i’m in amended soil. this one doesn’t as i caught it earlier

Thanks @Slater You've put my mind at ease.

Light's been raised and I've upped the cal-mag a little. I guess I was a little wary adding too much of anything in the early days.
I'll let you all know how they're looking in the morning, but growth is definitely speeding up and the new leaves are looking healthy so I guess I'm in the clear.

Thanks for that pic too @Medimadness yep, looks like a similar issue! I'd have hoped that i wouldn't have made such a rookie mistake but hey, each grow throws new challenges eh...

@NiceOption precisely man. I've been helping friends grow, doing a fair amount of work for one of them with bad health for around 2-3 years now and actually studying horticulture but without his watchful eye I'm not finding it easy. It's all the intricacies we've got to learn yet, every plant is the same, and living thing I guess, is the same

Mistakes are great though, nothing makes you learn faster than a potential dead plant that you poured a lot of love in
