Ilness or deficency?
Kynarethstarted grow question 3 years ago
Hello
I have noticed some lack of green and brown marks on some leaves. They are all from one plant and mid-low distance from light.
You think its nutrient deficency or some ilness? I have noticed that the coco was really dry so i opened a bit more the irrigator.

Check the PH first before you do anything. Then check run off for salt build up- if those are fine then its likely nute burn from this.. keep this in mind, if you dissolve nutes in water and give it to your plants the coco sucks it up and if you allow all the water to evaporate then all that is left is super strong nutes in the coco. Your best bet if you check PH and its fine is to run 2 times your pots volume (so 10 ltr pot =20 ltrs of water) of either plain water that has been PH to about 6-6.2 or a very weak 1/3rd strength nute solution thru it. That tends to fix most minor probs but dont allow coco to dry out fully as its very hard to re wet in one go. And just go easy on the feeding for a week before bringing it back up near normal.

Would start with checking substrate ph. I see some dark green in leaves which is too much nitrogen. If feed has been heavy, that will effect ph as well. Coco if that is all your growing in needs to remain wet.

Curliness if no wind damage is always overfed, so your question is wrong in essence ,;)

Leaves browning in multiple spots Lower leaves yellowing but have green veins.One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?

Burnt? PH lock-out? too much Cal-mag??What do you think is wrong with this plant?
All the other plants surrounding her are fine so I'm not sure what went wrong with this one. I thought it was cal-mag deficiency at first so I doubled cal-mag when feeding but it only proceeded to get worse. The buds look fine tho 👍😳
