answered grow question 5y ago
This book I have says nitrogen deficiency shows as yellowing tips of leaves starting with lower/older leaves. I’m on my first grow too, so I’ll defer to others and am interested to hear what it is.

Seedlings going yellow
Could yellowing of leaves on seedlings be from too much fertilizer ( liquid fish, compost,seaweed type.) I wouldn't suspect iron deficiency as it is new premium potting mix that they are planted in. I did feed with about half strength liquid feet about 5 days ago.

Yellow dot on the leaf.
Yesterday I watered with fertilizers. The dosage is 0.8 grams per liter. PS in the area of 5.5. The instructions say 4 grams per gallon. 1 gallon = 4.55 liters. Everything seems to be correct, so I do not understand what the problem might be.

Leaves getting yellow and rolling up
Hello. I noticed this morning some leaves have their ends getting yellow and roll up to the center of the leaves. Some other leaves have very tiny brown dots. Only one plant shows up this phenomenon, others are ok. Ph is 6.5 for watering. Any ideas? Advice? Thanks for helping

What nutrient deficiency is this?
What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

Yellow leaves near the harvest
This would be my last week of fertilizer watering. And the plant has the leaves turned to the side and with yellow spots. Sign of lack of zinc? I would start making the flush from Friday, is it recommended to start now? In about 2 weeks I will harvest (I tried to water today)

Yellow tipped top growth
My plant has had these yellow tips for a few weeks now. Seems to only be affecting the top leaves and doesnt seem to spread any further than the tips. 3 weeks into flower and her buds aren't fattening like my others. I added more P. Any ideas? She has plenty of micros...

Yellowing leaves mid-flower, sulphur lockout or just normal progression?
Noticed a few of the smaller lower leaves on a couple of the plants are doing this. It is still very few, so I am not quite panicking yet. I am going to recheck the pH on my res. No nutes, hot soil. Could this just be the natural progression of the plant as it builds buds?

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!
