Weak yellow leaves with red Stems

Lazarousstarted grow question 5y 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.

Seedling advice Hi, my light was at 60cm with an average humidity of 70 degrees Celsius. There’s slight dryness around the tips, yellowing, crispness. Remedy thus far: I moved the light up to about 75 cm, it’s a 100W led. Humidity also dropped to about 60 degrees. Any advice to remedy?

What do you think the problem could be?There’s something going on with some of these plants and I can’t seem to identify the problem so far. I have been doing a lot of research and I’m in a process of elimination at the moment but the plants growth hasn’t been affected. I will continue to try treat the problem.

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same. I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…
