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.

Yellow blemishes 1 week old seedling is starting to develop yellow blemishes on initial leaves. Soil is biobizz lightmix, PH 6.2 from bottled water with no nutes, 150w led light is at 50% and 25-30cm distance. Is it a cal-mag deficiency, light burn, genetics, or just too soon to worry?

Yellow Leaf Tips with Brown Spots – What Could This Be?One of my plants has yellowing tips on some of its leaves, and there are also brown spots forming on these yellow areas. Any ideas on what could be causing this? Could it be a nutrient issue, or is it maybe related to pests or environmental factors?

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?
