Is it natural?

Hey there, unfortunately my friend this is magnesium deficiency. This you can see from the yellowing on the sides of the leaf. This is not due to the nutrients actually but the light schedule. 18hs means the plant goes in photosynthesis "overdrive" meaning it needs more magnesium per day than normal. overtime you find a deficiency. To stop the problem from spreading add calmag more regularly as well as lower the light schedule as much as you're comfortable with. Remember : THC and Terpenes degrade with light meaning less light often means more potent product 😉 Hope this helps 🚀

Older leaves do die off but if it spreads quickly up the plant then you have something going on. Best way to tell, check your runoff ph and ec levels to know where your at. Cheers friend

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.

3rd week since 12/12 and chlorosis is getting worse !!! Will my crop be crappy ?Brought EC to 1.6, added 21ml of calmag, had to add 2L of osmosis water because the EC was 1.78. I changed the bad Ph probe and I let it fluctuate between 5.75 and 6. Should I remove the aluminium foil on the pot to let them breathe ? Not sure they are overwatered, I'm desperate

On the 31st day I noticed that, in both the plants, the leaves started yellowing from the bottom of the plant! For now the yellowing reached the first couple of fan leaves.
You can see that in last three photos.
Could be some pH issue or some over/under feeding?Week 5
