Whats wrong? Nobody has been able to tell me the issue and there is nothing on google. Had to leave them like this since i cant fix a problem i dont know what is.

for some reason one plant started to curl and dru up and in as a ball next the other one does too , now the 2 small plants are damaged and the 2 big ones only slightly.

not a PH problem! i use biotabs starterkit for mutes and biobizz lightmix, i water when light and dry every second or third day.

temp 26 - 30
Humidity 35 - 50
Hps 400w 40cm away

They look like they have severe nutrient burn. And why did you remove every single fan leaf?

It is not possible to overfeed or burn the plant when you use the ORGATREX, when you stay within the parameters provided on the label, don’t exceed the directed amount, please.

Now are you growing in coco and do you use c02 By the looks of it you were closer to- 28-30 most of the time and that is to low of humidity for 28+ temps. Just from my own exp as a example. if you run 25 C with proper VPD and your plants can handle a constant run off reading of 1200ppm and then you jack it to 28 C with that ultra low humidity you need to pack off the nutes to 750ppm run off. Those high temps and Humidity will have that plant using twice the water and that means sucking up more nutrients.Nutrient burn looks different at higher temps more like a potassium shortage.High temps with cannabis is like driving a race car it you can keep it on the track awesome but one little screw up and here comes the wall. I would flush with zyme or some other flushing agent a lot and then start off with half nutes and water everyday if your in coco. Hope this helps and post a pic of your fertilizer bottles.

It's nutrient burn. Those biotabs are timed release so it wouldn't show up immediately.

Nutrient companies make false claims. Your plants are definitely severely nutrient burned. It doesn't matter what the company says. They can say anything they want.

Hey man I'm new but had similar hard to diagnose issue and it was my EC cos of my shitty tap water (6-7.0) so if your not checking EC and using tap water? Could be your issue, I'm no expert but I haven't seen it mentioned and it's a finicky thing if it gets too high your plant can't take up water and suffers

Thanks for all the answers!!! Now what do i do? I had 2 biotabs pr plant so i removed 1 from the 2 very damaged plants, and left the two others.

Hahahaha i know. Ph isnt the problem, they claim you dont need to check ec and ph, but i have done it anyways mostly. Its not coco its soil. // But should i remove both of the biotabs or only one of them, and should i flush or would that make it worse

Are U checking runoff or just inflow? Cos shit gets higher at your root zone.

I left mine in the rain and they slowly fixed themselves. the pH of rain here is 8 so maybe try flush with high pH low EC ? lost the flower time tho they don't get it back.

how are you so sure its not your pH? you didn't mention any numbers. Have you even measured it? And not the water going in, i mean the actual root zone pH. Definitely burned to hell also, Ive got a feeling your pH is off too.
