Temperature is a constant 72-75. Its winter here now so it stays that low even with the 300w LED on.
Soil i first started with soil from outside my garden, then i transplanted them into "Professional Potting Soil with added coco peat and fertilizer" (found out today it has added phosphorus) .
I have filtered water at home so i water with seaweed extract. But now I have watered with pure filtered water only in case it was nute burn.




Before I transplanted I did add some calcium balance to the soil, could it be that? But my strongest plant was planted in the exact same way and same water and check the difference :O which is why this completely astounds me




Boron, interesting, that's what I thought at first as well after my research.
Hmm... as for the xray scanning I'm not sure if it will damage the seed, otherwise im sure many overseas growers would be having a hard time with the same problem haha but i think you could be right about the dna problem...i mean if animals can have genetic disorders im sure plants can too, unlucky seed i guess



That looks exactly like what i have! But do mites spread? because none of the other plants have that discoloration.

Your soil does look a little mulchy. I'm just saying. I would say your soil might have come with that. I am not really sure what ya got going on.

Dude those look exactly like mine did! Ended up being a combination of pH and overwatering, and a cal/mag deficiency.

They looked literally exactly like that. I'll try to remember to get on here and post a pic tomorrow morning.

Do you pH your water? Have you tried giving them just cal/mag and some plain water, ph'd? Worked wonders for me! Still have a fan leaf or two lagging behind but everything else recovered well.

Thanks! does that mean i should water less frequently? I've reduced it now to once like every 4 days and the smaller seedling pots still look pretty moist....im not sure why the plants aren't drinking :( pH problem? I am getting my pH meter hopefully on Sunday and would love to sort this out

Thanks man! That is the one thing i wasn't able to check was the pH level of my filtered water. I didnt pH it down in case i over do it so just plain water with seaweed extract. Now i stopped the seaweed extract all together because i thought i was nute burning. I will try plain ph'd water with cal/mag and see what happens thanks!!

what soil? It all depends on how you water. Are you drenching them. Are you going for 5% or 25% runoff? What's up fellow grower?

I'm using something from my local depot called Culterra Professional Potting Mix, with premium fertilizer and coco peat added. Heard the salesperson say was super phosphate. i water with a plastic jug and i circle around the plant and i flood it a little and let it sink into the soil. (Sorry but what is runoff? meaning let 20% run into the basin or 20% run out the pot and then put back into the basin?) Whats up :)

If you can get yourself a watering can that will allow you to water and at the same time allow for the soil to breath. Drenching is fine but it could be waterlogged. The spray of the watering can is like rain, wich is what cannabis was watered with all on its own back in the way back day.

Not really sure since I have brain damage, less than 10 years but more than 4 indoor, been putting seeds in the dirt outdoor with no success for more than 20 years. I have one keeper,7% cbd/thc 1/1 ratio and I may have a potential keeper in flower if it will reveg, God willing.
Thanks for the compliment but I think the light was hiding the chlorosis, Ill get more pics later after I shower and get rid of outside clothes.

Sounds good, let us know how it goes! It's real easy to go heavy on the nutes. Normally kelp is pretty mild. Just go like 1/4 strength at first and up the dose every week or two by 1/4. And make sure you let the pots dry our real nice between watering.

Post more pics too! lol

I see! Would the curved leaves and colour be part of the genetics of Sour Diesel?

Hey guys, so latest updates on my grow, majority of the plants have their cotyledon (1st pair of baby leaves) turning yellow or drying out :( is this a sign of nitrogen deficiency? I'm really sad, everything was going well and now all these problems are happening.

The cotyledons dying is telling you they are almost ready to be fed nutrients, when they start to get lighter green give them 1/4 strength to start out.

Hi fellow growers!

I am new and started two batches of seedlings currently in veg and around 3 weeks. All are relatively healthy except some that have showed signs of nute burn so i have been carefully flushing them slowly.

However, this one particular plant is displaying really strange colours and the leaves are deformed and curling only on one side always, becoming a claw. I really want to learn more about this and do my best to keep them healthy so i have spent hours researching and trying to find the answer, but to no avail. I am constantly confused between nitrogen and calcium deficiency or excess.

If someone can please help me identify this and why one side of each leaf is not growing and the really strange light green colour, it used to be much worse.

90% of the disfigurement is a genetic disorder, malignant . A plant cancer that most cannabis plants will grow out of.

You're doing fine man, the cotyledons will always yellow and die off. They're meant to. Just give them some 1/4 strength nutes like suggested above, that's good advice. Do not go crazy and give them anything more!

Thanks for the support and advice fellow growers! I do feel a little less panicked and just sit back and watch them grow. I just wana to make double sure, liquid fertiliser like the one they use for hydro grow is fine for soil right? Just mix 1/4 strength as you guys mentioned with some water and feed like that? I read in the guides that for NPK during veg they need more nitrogen and potassium. During flower is more phosphorus and potassium. Correct?

Hi lino

I'm not too sure what is florescent. Do u mean CFL lights? OK cool didn't know that! Is the LED 300w too strong in the beginning? I realised I may have gotten soil that's too hot for the seedlings and should have gotten seedling potting soil as opposed to professional potting soil which I got.
