Hi you need to increase your bloom nutes as its eating through phosphorus at the moment. Try 1.5ml/L or 2ml/L

What are my leaves telling me?
Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

Autogrowing
Auto flowering, PH is 5.8 to 6.1 every day. Hydro set up. Botanicare grow, calmag, and hydroguard all given half the regular amount.
Finishing up second transition week. The bottom leaves started turning a little yellow but are now turning a lot more yellow. Assuming this is the plant just using it's own nutrients stored in the lower leaves. Any input? It's a hydro set up. Thank you everyone.

Bottom leaves turning yellow, with brown spots. And the tips of the top leaves are yellow aswell.
De onderste bladeren van mijn plantje hadden in het begin witte vlekjes en nu zijn ze helemaal geel. De bladeren daar boven worden nu ook geel, en er komen bruine vlekjes op. En de puntjes van de bovenste bladeren zijn ook geel. Wat kan de oorzaak zijn?

I need help troubleshooting weak plants! I think the clover might be the culprit but what do I do?
Can anyone tell me what’s going on with these plants and what I can do? This is my first grow. I can already tell the seeds are growing slow because other seeds I planted in smaller pots are growing much faster. Any advice would be greatly appreciated!

Why do I have rapidly spreading yellow on my leaves?
I have this yellow spreading on some of the larger leaves and it's moving super fast. Please help. I've done research and it says it's a deficiency, mostly likely cal/mag. I added that and it got worse, now I'm thinking nutrient lockout? The pH is fine. What do?!

Manchas en hoja
Hola! Aparecieron estas manchas en una hoja de una GG#4 de zamnesia en su quienta semana vegetativa. No es algo que me preocupe, ya que la planta tiene una apariencia sana y crece vigorosa. Pero nunca vi este tipo de manchas y me gustaría saber su posibles motivos. Un saludo!

IMPORTANT excess/deficiency? What's happening? Flowering is in danger
What's happening here? I think it could be Fe deficiency, Mn deficiency, S deficiency or maybe K excess. But I'm not sure about diagnostic and I think I can have more than one problem. Please help, I don't know how to solve it and I see how flowering is very slow and weak

Help validating what this is
My plant seems to have developed some kind of deficiency/excess. I researched and think that it's CalMag deficiency, added CalMag to my nutes (1ml/l). Just wanted to check in with the experts here to get a second opinion. The growth seems slow I'm afraid I may have stunted her 🤦

Rate the Bud - 6 Week completed flowering
So this is my first time growing with using BioThrive grow, bloom, calmag bottle ferts. Would greatly appreciate any feedback on improvements, those 2-3 leaves with yellow spots seem concerning. On 'honest' scale of 1 to 10, how are my buds looking for week 6 in flowering?

Deficiency?
My current grow is on its 5th week of flower and many lower leaves on each plant have begun to yellow then develop brown spots. I’ve did a little bit of research and I think it could be a nitrogen deficiency. Any help is appreciated.
