Discoloration of some leaves
SpiritLevelstarted grow question 4 years ago
Hi all, For my question please see the last photos uploaded to my grow. The leaves shown are growing on the bottom of the plants, going from bottom to top, starting from the main stork. Any idea what this is? We’re thinking a deficiency if some sort, potassium or phosphorus maybe

She may have N toxicity from the looks of those dark green leaves that are beginning to yellow and die. Check the pH and ppms of your runoff. I'm guessing your pH is too low and your ppms are too high. In this case do a nice flush. Next best bet is adding some calmag and being sure not to overwater.

Potassium deficiency?Needing some help. I have this going on in my flower tent. They are in week 6 of flower. Of the 4, I have only one showing this bad. She seems to be locked out on me as well. Could this be a potassium deficiency? Seems to only effect upper fan leaves.

Spots on leaves after spraying with Plagron Vita RaceOn the 4th of March during lights ON I sprayed my plants with distilled water with Vita Race (3ml/L). I noticed that after it dried up there are some weird spots on the leaves that were left behind (see picture). Any idea if that can lead to problems later?😅

Bad appearancethe leaves seem a little clear, strange, I don't know if because they are new, but before they look darker, the amount of nutrients seemed good to me before, but I increased the N to see if that corrects it, I would like more accurate views. I have another genetic using the same

The leaves are large and big but sooo thin! Burntips and little holes.Does anyone know what could it be?
Got a tipburn in one leaf and 2 others with extremely little holes, but didn't see any bugs or look-a-likes in my grow.
Is it normal to the leaves be so thin? It's my first indoor don't know if indoor plants used to be like this.

Too late for another trimming ?Show I do another trimming ? Most of the big upper leaves started having trychromes at their base so I am not sure if I should trim again at this stage.
Currently in the 7/8th week. I already trimmed twice during vegetation and beggining of flowering.

Found something weird on my new leaves. Need an expert's opinionFound something weird on my leaves. I need an expert's opinion and insight. I don't know if it's natural to occur on newly developing leaves or if it's an issue that needs to be addressed. I'm thinking it might be natural but it seems weird to me.
