Weak yellow leaves with red Stems

Lazarousstarted grow question 4 years ago

Weak yellow leaves on the bottom with red stems. I use 1/3 tap water, 2/3 filtered water for its pH levels. Could that be my issue? I feed twice a week Fox Farm Big bloom 2ml/l, Grow Big 2ml/l and Cal/Mag 0.5/l. Cal/Mag with every watering to make up for the soft water.

Too much calmag can lockout potassium, so that's possible. That Looks like it might be you first true leaf. If it is and you're already into week 4 or beyond, losing that leaf is completely normal. If it's still early within 2-3 weeks old, it's almost definitely nute burn as they don't need nutes until the end of week 3 usually.

Bottom leaves yellowish - why? And can I top?On both of my plants (C99 & S.A.D.) the bottom leaves are turning yellowish and I can't figure out why. I'd also like to top them this week (above 3rd node), but I'm hesitant because of the leaves. Any advice on what they may be missing, and whether I should wait with topping?

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥

Brown spots on top leaves - nutrients, light or something else?She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each). 3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves. I suspect this could be light burn or nutrient related. Any ideas? Pls help

Nitrogen deficit?The bigger plant is struggeling a bit again. After some talks and readings it could be a nitrogen deficit but am not really sure how if I should react to it, since the need of the plant should get less for nitrogen in the next weeks. Please read my journal for more information.

Upper leaves are yellow and not smooth I noticed leaves on top are closing and today are yellowish. Older plant aren’t stretching more, I thought it’s too much light or too hot but it’s kinda weird because light are at 40cm from longer plant and 50 from smaller, temperature are max 26C. So, it’s normal?
