Yellowing tips on new growth. Opinions?

That is a very interesting and positive perspective to have, well done.

Thanks for the confirmation, guess I’ll let her ride it out and keep monitoring her.

Haha that’s ok, everyone has their own way of growing, whatever works for you :wink: You’re getting nice results so looks like it’s working.

Hello again, back with more bad news :confused: The plant was doing better yesterday, still with some yellowing tips on the new growth, but not as bad, then I come home today and find her with brown spots on some of her fan leaves :confused:

Here is what she was like yesterday:



This is today:





Just did a fresh nute mix yesterday, Week 3 of AN, 820PPM, pH 5.7. Took pH readings of the run-off, 5.4. What am I dealing with here? Nute burn? Is the plant cannabalising itself? Maybe the DLI is too low (it’s at 21 on this plant, I’m trying to accomodate the seedlings next to her also at DLI 16.

@Graysin just tagging you in here cause you’ve helped me out a great deal in the past. Maybe you want to pitch in with an opinion. No hard feelings if you don’t have the time.

Thanks in advance everyone, been a troublesome grow from the get-go.

Ph is definitely low if you’re going in at 5.7 and it’s coming out 5.4, I would imagine the actual ph of the root zone is potentially a little lower then 5.4 even as the higher ph going through would bump it up a tade bit as it balances out.

Below 5.5ph alot of stuff gets locked out.

You can try going in at a higher ph a few feedings, 6.0ph upto 6.2 even.
Hopefully just 1 day will correct it but if it was me and after 2-3 days if that and still no improvement, I’d go for a full flush till I get ppm comeing out 0, then a fresh feeding…

Hello again @1HappyPappy thanks again for your prompt input. I can’t up the pH feeding, I use pH perfect from Advanced Nutrients which locks in the pH at 5.7, I have no way to change this :confused: It is part of the base NPK nutes, not something I am adding in afterwards.

So, here is what I was thinking:
Start by watering the plant with RO water and hydrogen peroxide. Given the state the plant is in, should I use your ratios (the plant drinks about 1.5 litres a day currently), this will only be a few ml of hydrogen peroxide given your ratios, or should I drench her with the 2/3 ratio that @Myfriendis410 suggested? (This will be around 1 ltr of hydrogen peroxide in from 1.5 ltrs total)

After that I’ll give it a flush with 25 ltrs RO water.

Should I let the hydrogen peroxide watering stay in the Coco for a day, then proceed to flush the next day? If I do this, should I feed the plant a nute mix after the h202 drench,or leave it a few hours then feed?

Just brainstorming here but could humidity have something to do with this? It’s awfully low this grow, around 52% most of the time. Usually when I have 3 plants in Air Pots they get the humidity in the correct range for me, but this time I had some trouble sprouting some old seeds, so 2 plants are still seedlings in small pots barely contributing to humidity.

Thanks again for your help and advice.

Oops, small correction to the above, meant 500 ml of hydrogen peroxide to 1 ltr of water.

So, an update. Mixed 500 ml of hydrogen peroxide with 1 ltr of RO water and watered till ample run-off. Let it sit for an hour or so and did a flush with 20 litres of RO water at 40 EC (20 PPM). Run-off pH rose to 6.9, EC dropped to 104 (52 PPM).

Fed 2.5 ltrs of Week 3 mix (1667 EC/830 PPM) which gave run-off readings of pH 6.3, EC 245. This is how the plant is looking :confused:




Thinking of making a Week 4 mix tomorrow (the plant is 36 days old from sprout), and start reintroducing the microbes again.

@1HappyPappy had you steered right. PH lockout causes artificial symptoms that people start to treat as deficiencies without recognizing that it’s just pH problems :slight_smile:

Hello @Graysin, thank you for your input, it is always appreciated, hope you are doing well. Sorry for the delay in my reply btw, been super busy. Some good news at least, the plant is still growing fast and responding well to the manifolding, still has an abundance of yellow tips everywhere though but at least the brown spotting stopped. Took pH readings today of the run-off, came in at 5.5, already low considering I just flushed exactly a week ago. Run-off EC was 840.

Here’s what the plant is looking like:

The other 2 are looking quite healthy thankfully, they were transplanted 2 days ago. I’ll be manifolding them sometime next week I reckon:

Hello again everyone, need some guidance here. I have 3 plants, 2 sprouted 3 weeks after the first one. The first plant being 3 weeks older overgrew the other 2 greatly. This is what I’m facing:

All of them have been manifolded, but the 2 smaller ones on the left just finished the manifolding process 3 days ago. (Cut off node 4 and node 2) I didn’t think the bigger plant was going to overgrow them so much. The light while not photographed, is exactly at the top of the image and I only have about 5 inches more headroom. I’m worried that the bigger plant is going to grow into the light. What course of action would you all take? Should I flip to flower now and cut my losses with the 2 smaller plants? Get another net and try keeping the bigger plant flatter? Opinions would be really helpful, never had a problem like this before.

Thanks in advance as always everyone.

Couple of options i would do if it was mine.

  1. Put something under the shorter 2 just to get and even canopy, milk creats, block of wood, or just whatever you got handy. Defoliate real good for air flow and flip them.

Or
2. Cut the taller one down to match the size if the other 2 and veg on.
You can take a maximum of ⅓ of the plant easily.
In the past I’ve choped off entire branches and just made plants fit a space. Its a good benefit of photos, you can shape them any way you want and with a nice healthy plant, you can be pretty aggressive and she’ll be fine.

Or option 3. Order another tent setup :sweat_smile:

Thank you for your suggestions @1HappyPappy I’m very interested with your 2nd option, this will give me more headroom for the lights, and also let the smaller 2 bulk up a bit. I had just lollipopped the bigger plant 3 days ago:

So, I just cut off most of what is above the net and let these lower growth tips be my new future colas? You said I could take off 1/3 of the plant, so should I still leave some stuff above the net and weave it under the net or everything above the net must go? (I think this will be more than 1/3 of the plant.) Should I wait a few days to do this since I just lollipopped? (to let her recover from that a bit)

Thanks again for the opinions, very helpful. Oh, and your option 3 would be the best haha, just don’t have space for another tent.

Just posting a positive update :slight_smile: things are looking quite well now, I took your advice @1HappyPappy and trimmed down the bigger plant, now they’re all quite similar. Flipped to flower 5 days ago. Here are the girls:

Hello @Graysin, always a pleasure hearing from you. Thanks for checking in, I appreciate it ^-^ hope you’re doing well on your side :slight_smile:

Progress is very good, the girls are looking super healthy (healthiest from my 3 grows), they just overgrew and got too close to the lights. Learned a lot from this grow though. Due for a defoliation today. Here are the girls:

Have around 40 - 50 days left according to the breeder info.
