I think it is a ph issue at your roots. One thing is for sure the plant does not require a lot of nitrogen at 47 days into flowering. Then again I grow in coco when it is a serious grow, so i might be out to lunch. If you had the same issue with your strawberry. then I would do the same thing you did..I have had root issues this grow and resolved them by adding a enzyme additive. The abundance of enzymes eat the build up of salts and any issues from over watering.

good luck with the resolution and grow.

Thanks for the tip.

[HobbitGDF]

Ok so I uppotted the yellow plants into bigger pots. Also watered them with Epson salt & lacto. Hopefully they will feel better soon and be a darker green again

[Franklin]

Hope this works out, definitely let us know. So cool to see the difference in leaf size between the clones and the seeded plants. Those clones there looking like dinosaur leaves almost. What are the variety differences for those again?

[HobbitGDF]

The clones are LMFAO by elev8, cherry gar-see-ya by ethos, & Island chill by exotic genetix

Help! One sick Gelado!

[Rwise]

Tell us what the roots are in, looks like PH issues.

[ChubbNugg]

check miracle grow soil for paraquat. some coulda leaked in.

[Puglover1]

Other plants/strains are OK?

[Going2fast]

Having an issue with hubba bubba. Leaves at the top of the plant are yellowing from the edges in. Just started happening on Galaxy but not as bad. Oh is ok. I'm leaning toward light burn or possibly potassium deficiency. Moved the lights from 16 to 24 inches away to see if this helps. Ahh the joys of growing multiple strains at once. They all have their own special needs.

[changeofpace2014]

I think light burn would of smoked them fine pistils first, or at least my lights burn off the pistils long, before any leaf damage is done...I had to recently move my lights from 11" back up to 15".

[Blowdout2269]

Think ya got it figured out?
If this edge yellowing is mostly towards the top of the plant, I'd say that your ur correct assuming potassium deficiency.
What's the treatment plan?
Sorry about the late response. I always forget to check this topic, lol.

[3Berries]

I usually get that and have narrowed down to K. Lights (growth) aggravate it as it's driving it lean.

[Going2fast]

She's drinking 3 quarts daily. Pretty sure she's exhausted the soil nutes. Do have a bottle of 0-5-4. I'll give them a feeding for a few days and see if she improves. Would make tea but my compost is too high in nitrogen for this stage in flower.

[Going2fast]

I let her dry out good then watered her with half strength bloom nutes 0.4-5-3 and water pH at 6.5 and moved lights up. Monitoring

[Elias2107]

Nute problem any help?

[3Berries]

Calcium deficiency is my guess.

[Bluey]

I'm guessing pH..

[changeofpace2014]

I would thin that girl out and get some air movement around your plant...What are you growing in? (dirt, coco)..How wet are your girls (how heavy is your cloth pot) before you water.

[Elias2107]

I use dirt to grow in mixed with perlite to keep airy. I also feed the plant sensi cal mag extra so I dont think it is a calcium deficiency however could be the opposite since add more of it compared to the other nutrients. I use a fan to keep the air moving but dont aim it on the plant. I wanted to thin out earlier but it is an autoflower and it was to late when it started flowering. Read somewhere that that decreases yield.

[Bluey]

Any idea of the pH at the roots?

[Puglover1]

Elias2107 In your first pic the soil looks kind of compact. Did you use enough perlite ratio when mixing it?

Help! I’ve been dealing with these root borers in maine for the past 2 summers now, I just went out today to clean out my pots from last grow and found another one still alive in the stems after months of winter, I’ve tried everything to get rid of them but nothing seems to work, wondering if anyone has any advice or if anyone else is having this same problem

[SoOrbudgal]

Terrible but fixable. I would start by placing your pots ( i only grow in 15gal outdoors) up on blocks not on the ground and away from bushes or trees if possible. Do not reuse the soil probley eggs in it so destroy soil start fresh. I've not had root borers but do get moth catipillars mid to late summer that eat the buds. I do not know what else to say on pre treating if it's even possible with that type of " maggot " .

[Rwise]

It will help to burn all remaining roots, stems, etc.. As you have found borers can winter in them.

[Elias2107]

I give these plants (gorilla cookies fast flowering) EC 1 ph 6.2 with 2,6 ml canna vega, 4ml rhizotonic per liter. Temperatures are around 20 Celsius but can sometimes go down to 15 degrees Celsius. I have had them in the open because I thought the stems were real weak because there is no ai circulation but now put it back on. I hope I can get a tiny pc fan soon to fix this problem. Any other suggestions?

[Elias2107]

I put on the lid again but opened a few holes at the top so there is no to high humidity. Also started giving plants lower EC because they are not taking it so well I think. New EC is around 0.5

Hello Elias2107!

Glad to see that you're growing! Is this your first grow or have you been growing a while?

Taking a look at your pics and reading your post, it looks like your little seedlings are suffering from what many new growers to - giving their plants too much love!

When cannabis plants are seedlings, they're very tender and fragile (I've never had a kid, but I imagine that's what babies are like?) and while they are resilient thanks to evolution, they can suffer from too much attention and care.

Seedlings are extremely special in that they initially have all the food and nutrients that they need to get started so no nutrients are needed. So if you're giving them any nutrients, that can probably stop for now. They're also sensitive to chemicals so if you're adding any pH-up or -down, you might want to cut back on that as well.

It also looks like your rapid rooters are extremely wet. While water is essential to plant growth, when they are seedlings, their roots don't really have the capability of absorbing much of it. When they first pop, seedlings actually take in more water from their leaves than their roots. If you're thinking, "Gee, maybe that's why seedlings like higher humidity than adult plants?" you're absolutely correct! Also, when seedlings are overwatered, it actually suffocates the roots causing all sorts of problems. Roots need oxygen/air as much as they need water.

Your little seedlings are looking pretty rough, but by going a little more 'hands off' you might be able to salvage them. My suggestions:
- Stop adding nutrients for now until they're bigger
- Stop watering for at least a few days.
- When you do start watering, give them VERY LITTLE (when my seedlings are that big, they just get misted using a sprayer. Once they're growing strong, I start doing about 1 cup (about 250mL) every 2-3 days)
- Also when you water little babies like that, try watering in a circle an inch or two (3-6cm) away from the base of the stem. This helps keep the medium wet without drowning the developing roots.
- And in general, you want your temps to be between 68-77F and humidity 65%-70% during the seedling phase. However, it appears that the watering issue is more prevalent than your environment at the moment.

Good luck, keep us posted, and remember that (usually) less is more with cannabis!

[Elias2107]

I was using ph- but I will take your advice and keep it on the low with nutrients from now on. I hope it’s not to late for them and that they will still be able to recover. I’ll update if any further problems show up. This advice has been great, thank you allot! 👍

[AGH]

You're most welcome! And if it all ends up going sideways, all that really matters is that you learned something for the next time around. Sure, you were hoping to end up with some tasty buds, but a new wrinkle in your brain is a pretty good runner-up and you'll be able to do better next time :-)

[Elias2107]

Since last time I posted, sadly my young plants died ;( but I learned some valuable information at least. Now with my older plants, they have started to show some signs of a deficiency and the lower leaves are looking droopy while the upper ones are strong and healthy. Any suggestions

[Blowdout2269]

I agree with @Bluey.
Tell us more about your grow?

[Elias2107]

The temperatures are between 18 and 25 degrees Celsius. The humidity has been a little on the higher side a while a go (70%) but now it’s mostly between 45 and 60. The food I gave them last time was (20L): Canna Flores 80ml, Canna Zym 40ml, Canna Rhizotonic 10ml, 60ml Canna Boost, 40ml Fulvanic Acid (new) pH: 6.2 EC: 1.5

[Bluey]

The nightime 18⁰C can you get it over 20⁰C?
Ideally you should be at 25 to 29 depending on RH of course of a day and 3 to 4⁰C below that of a night. I'd try lower the upper humidity if you can without lowering your lower humidity also...but match your temps to RH for a VPD of maybe 1 2 to 1.6 and tune that with your lights...the good leaves will tell you everything you need to know

[Blowdout2269]

What's in your soil and how are your watering habits?

[Elias2107]

My soil consists of wood scraps, coco’s scraps, rice husks, green compost tree bark, terracottom, chalk and fertiliser. NPK of 15-10-20. This is mixed with I think 1/4 perlite.

my previous mix (which I’m not using now) consisted of: Plagron light mix 50 L, 1/5 perlite, 25 big spoons of plagron mega worm mix, topped of with 15 tablespoons of Eifel gold lava powder.

Which one is better and what do I need to add to my mix for even better results?

[Elias2107]

I got rid of the lower leaves, but now the higher leaves are doing the same as the lower ones. The problem has only risen to the upper leafs now. I personally think it’s a sickness because the plant is not drinking as much as the other one too. I don’t know what to do to fix this. My soil consists of: my previous mix (which I’m not using now) consisted of: Plagron light mix 50 L, 1/5 perlite, 25 big spoons of plagron mega worm mix, topped of with 15 tablespoons of Eifel gold lava powder. And my nutrients consist of: Canna Flores 80ml, Canna Zym 40ml, Canna Rhizotonic 10ml, 60ml Canna Boost, 40ml Fulvanic Acid (new) pH: 6.2 EC: 1.5. Any suggestions?
