I have a nutrient deficiency or something else tha...

hey there that was actually a magnesium issue which the plant has muscled through, next time add a cal mag spray 1ml/L and it will largely avoid such a problem. Hope this helps ! 🚀

Looks like you are giving her to much food do your research on your nutrients they are not mixing well ph is out the question u are using ph perfect nutes this could be throwing something off✍️✍️✍️👍👍👍

Since there are no previous weeks to view I would not hazzard telling you to do anything but the basics. How stable is your PH? How is your water? How often is it flushed... I mean a whole list of things Sometimes waiting is a necessity Start there, for one it will keep you from adding something you shouldnt. Keeps me out of too much trouble

@seagull Looks like tobacco mosaic virus to me as Ive had it on a few seedlings all of which ended up being completely fine other than the obvious leaf markings I think 5.8 is atad too low for your medium and 6-6.2 would allow more nutrient availability to the roots

a f i having no more picture, it looks like tmv.... the plant show that signs in very early stage. so if she had that from beginning.it is TMV..... if not we have to look closer. and do a new diagnois. there are a number of other factors thaat can cause discoloratings.but i cant sa more because of less informations

Hello my friend For me lack of k If the EC of the substrate or soil is too high, you should rinse thoroughly with pure water. You can add potassium yourself, the easiest way being in inorganic form, by dissolving 5 to 10 grams of potassium nitrate in ten liters of water. If you have acidic soil, you can add a little baking soda or caustic potash (5ml in 10 liters of water). You can also add potassium from an organic source with an aqueous solution of wood ash or manure (be careful not to "burn" the plant with a solution too strong). Extracts of substances like manure contain a lot of potassium. Over-application of potassium can lead to salt damage, calcium and magnesium deficiency, and acidification of the root environment.

I think I have a good answer: variegated leaf mutation :) I asked around and this is what I think we are both seeing in our plants.

Hello Seagull, your girls are looking good. To answer your question, im not 100% sure but it looks like you have the tobacco mosaic virus. I would look it up on the internet, if thats the case. Remove the plants that are effected withouth airflow, so turn of your fans before you move them around. If its als your plants or girls, clean and then deinfect your growspace with 3%hydrogen peroxide and invite some new girls to the party. Good luck my friend. Keep on growing. Peace 👍
