Terrible looking seedlings... :(

Try flushing with ph water at 5.8 but use three times the water of your pot size.1 gal pot use 3 gal water and so on.

Only water no nutes at all?

Anyone else have some thoughts or is it obvious pH problem?

What brand coco? Flushing it with just plain water may not have done the trick, because coco has some peculiar CEC properties... Have you read up on coco, and/or used it effectively before? It's sooo not soil, and if treated as such, problems are automatics... that said, this early on, i have to suspect it's the coco,.. a little late on the nute's, but it wouldn't cause such severe symptoms like this! Are you using Ca-Mg from the beginning? Coco needs this (related to that CEC thing), even w/o nutes! ..pH info needed too,... Symptoms are odd, looks a lot like Zn defc., mixed with pH issues or other defc.s,... bad coco can have too much Na and K in it, but I'm not sure I see toxicity issues...?

IMO they looked burned, sorry my friend but if that is an auto, I would not waste anymore time or nutes on it and would start some new seeds. If their Photo's they have a better chance to recover and might even surprise you!

Thanks @Waira

Its cheapo coco, thats why i flushed it real good before planting seeds. Which brand coco would you reccomend?

After flushing i did not do a last water through with any camg(AN sensi calmag) or even pH it.

Yep my last 2 girls in coco did awesome, but its just these 5 out of 25 that is showing problems..

Sorry to butt in but i was just curious and have a couple questions.What kind of water are you using? Are all of your plants autoflowers? Are they different strains? have you tested runoff?

lol, no need to be sorry I appreciate your interest.

Just tap water.

All these 25 in this tent is photo regs.

Nl5xHaze, Satori, Double Dutch, Papaya and Critical Mass.

I tested the runoff in my tray after flushing these 5 and the water pH was 5.8 and runoff was also 5.8.

Have you tested your waters ppm? Do you have any double's that are doing well i.e 1 out of the 5 not looking so well and one of them is papaya, do you have another papaya in the 20 good one's that is doing well under the same conditions?

Yeah from tap its 6.5+ pH i dont remember exactly.


Yep, 3 out of 5 Satori shows problems, 1 really severe(the smallest one).

Only 2 Double Dutch and they both look exactly the same.(the two tiny ones with curled leafs)
