Need help identifying problems

[Peff]

Yo

Could anyone help me find out what this is, and how to kill it?

I’ve had thrips for some time, think I have some kind of mites also fucking them up.

I’ve got californicus and hypoaspis on my plants right now, not sure I’ve seen em yet though...

1. Leaf Miners

Which you cantell from the holes in the leaf, eaten into the leaf from the top of the leaf down.

2. Some extra Potassium (K).

From the serrated leaf edge damage and slightly woody stem and purple leaf. They may also be slightly overwatered.

Otherwise, the plants are growing nicely.

I dont have any white trails on the leaves though, is that normal?

What made you able to spot the K deficiency? Thanks!

Would this be from a leaf miner too?

 

[Peff]

Wasnt any information when I first opened up the message, sorry lol

From googling them they seem to leave white trails which arent there?

They could very well be overwatered, which i’d guess is the actual reason since ppm are pretty high right now (1200~ ) so doubt theyre missing any K. How do I go on about flushing without overwatering? Feel like everytime I flush, no runoff until I add water one too many time and runoff becomes huge and they’re wet for a 4-5 days using Promix Hp with added perlite

While we’re at it, are those insects too? Scope broke, cant go for a new one till monday

 

[Mr. J]

If things are staying wet for 5 days after waterings then I would say that your pots are way too big for the plants and it's going to be impossible to flush things without drowning them.

Could it be that im not flushing right? Went from 3,5” pot to 6”, been two weeks, Im seeing some roots from the holes at the bottom from a couple of plants

Am i supposed to water until a runoff starts to come out, or do I have to wait a bit in between each 1L I give em to see if it’ll eventually come out?

 

[Mr. J]

You need to have your feeding dialed in especially when you have a big medium/roots ratio. Less is more at this point. If you have a small plant with small roots in a big pot you have to water and feed less. This gives you the ability to adjust things up because you'll never be able to effectively adjust things down until the plant is well established. I wouldn't be watering to runoff and I would be feeding a lower concentration until the rooots grow. If you've already overfed and they're too wet right now then that's gonna be a pain. I'd flush with straight water then I'd be patient and wait for them to dry before doing anything else.

Edges are starting to burn up on some plants, which is why I was trying to flush

Should I have done a smaller pot? Isnt 3,5 to 6” a good repot size? Considering I gave em two weeks before doing any run off I figured they’d be able to take it? Tips to get bigger/more roots?

You haven't mentioned what soil you are using, and I'm guessing that's factoring in here. It might be too dense and doesn't allow for drainage. Find a higher porosity soil mix, or cut your soil with some perlite or something.

He's using promix with some extra perlite so drainage shouldn't be a problem.

Like I said I'd flush good with water then only feed again when dry, and then I'd cut the concentration pretty much in half, from the 1200 you're giving down to 600 or so and see how they respond. If you let them sit wet with the high concentration solution the water will evaporate and the salts in the soil will concentrate further so pass some fresh water through and then wait for the pot to dry mostly before doing anything else.

Looks like the trifecta of beginner mistakes, pot too big, water too much, and feed too much. Those three things are what I see most from people just starting out.

 

[hush]

Well then yes, I would say this is a case of the typical beginners' problems of overwatering then. That is absolutely a common thread among beginners. It's rare that they underdo anything, and common that they overdo everything.

It's okay, OP. We've all been there. Just seriously cut back on watering, big time, and in the future you should use smaller pots and not up-pot until close to being rootbound. When plants are big enough, it's not a huge deal. But in the beginning they are babies, which need to be coddled.

- The pot being too big

All that means is that you water less often. Which is a good thing. More stability of the medium for the plant, less work for you. I plant in the same pot I harvest them in, because I don't have to move them. Outdoors you can even plant weed in the ground - no potsize restrictions at all. So personally I don't think the pot can actually be too big for the plant - all it means is that you water and feed a lot less frequently.

- Basically the problem is insects and K lockout because of overwatering

What I would do, is give the plants 0.4 EC of bloom food and 0.1 EC of epsom salt. Water very slowly and thoroughly (water the surface of the soil only, walk away for 10 minutes, and repeat - see how much water the soil can absorb that way before getting runoff, then feel and memorize how heavy the pot weighs). Then don't water again until the pot feels very light and the plant looks like it needs water. It's ok to water only twice a week, or even once.

For insects, I would mix the recommended drops of pyrethrum, vegetable oil and just enough liquid dish soap to dissolve the oil in water.

This attacks the insects on various levels - the pyrethrum will paralize them, the vegetable oil will suffocate them and the soap will dessicate softbodies insects. It is very effective against all kinds of insects.

However the underlying cause of the presence of insects is the relative overwatering.

 

[Mr. J]

There's nothing wrong with a big pot, but you'd better not overfeed right off the bat because making corrections to such a big mass of medium is a pain. Personally I think a smaller pot is better for beginners because the amount of medium is less and it will dry out faster, which gives you more opportunity to fix things if they go wrong. That next watering is that much closer, which means you can make adjustments more frequently if needed, and if you really need to flush you can do it without drowning a small plant.

Thanks a lot for the answers

You guys keep saying pot is too big, is a 3.5 to 6” repot too big? They were in the 3,5 for 17~~ days, they were way bigger than the pot they were in, most of them had nice roots going on while the others had less roots but the soil didnt break up when removing em from the pot, so I’d say they were rooted well enough? Also been 2 weeks since they’ve been in 6” and I’ve noticed roots in the airwells at the bottom of the pot for some plants, surely they should be able to drink well enough?

This is actually my 4th grow, first was abysmal while the rest were okay, nothing amazing, had a lot of issues with my old setup. Im by no means a great grower but I know most of the basics I’d say, i’ll definitely watch out for watering

Also, someone mentionned cutting ppm from 1200 to 600-900; i’m already feeding at 850-900, should I eventually go higher in flower?

Im actually right in the middle at 900ppm, would you still drop to 600 since theyre high atm? You guys are saying not to runoff just yet, but isnt that how salt build up happens? I wasnt doing any water runoff first grow and ppm were at 2-2200 during my last two weeks of flower, which is why I was trying to have a runoff this time around

When youre saying flush good, thats without a runoff right?

1.Flush out the soil 3x times the pot size with water!

2. Spray the plants with Pyrethrum 5EC, top of the leaves and especially under the leaves, the whole plant. This will kill the thrips and also your thrip predators.

3. Hang yellow sticky traps near plants.

4. Allow the plant to dry and the soil.

5. Re-feed the plant with 500ppm Grow nutrient and PH 6.5

6. Allow soil to dry

7. Re-pot and re-apply the Thrip predators.

8. Continue feeding with 500ppm PH 6.2 - 6.5 till plants show hunger.

I've basically just been through this situation

Also raise your light or turn down the wattage while they recover, Thrips also breed faster the hotter it is.

Thank you for this, temps are 24-26 in my tents, would you still drop temp? Just gotta up the AC

Ive personally not seen any predators myself, but I am seeing thrips still two weeks later.. had 20k per 4x8, shouldve done the job? Hydro guy said 20k for both 4x8 was enough

Would you have any idea what made the holes in the leaves? People are saying leaf miners, but they leave huge white trails on the leaves and I dont have any trails, just holes

Should pesticide be dripping? Ive had people say yes, some say no

How often would you spray? My friend whos been growing for 20years said to spray 3-4 times, every 3 days to get rid of every eggs that may have hatched but the hydroshop guy said not to do it more than twice

I have forbid and bug b gone(which doesnt kill thrips afaik?), ambush and sevin, both of those can be used in the soil to kill eggs

26 is fine, Defoliate the bad leaves and dispose, clean the tent.

You need Pyrethrum 5EC to kill thrips, spray day 1 then 3 days later spray again and 3 days later spray once more, only make 1 litre spray batch each time because it will degrade rapidly and wont work after a day or 2. so make fresh batches each spray.


After that, spray the plants with water to help wash any residue.

Then hang yellow sticky traps close to the plants.

Then add Hyposaspis Miles / Stratiolaelaps scimitus Predatory Mites to the soil after you have potted up.

Continue with 500ppm Feed & PH 6.3 - 6.5

Also wear a mask and gloves while spraying the Pyrethrum 5EC, it irritates the skin and lungs.

If your gonna spray insecticides they you should switch them up so bugs have less chance to build immunity. So maybe neem, permethrin and insecticidal soap as an example.
