Grow QuestionsDeficiency?

Deficiency?

ThatFcukinChronicstarted grow question 3 years ago

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.

Def a nitrogen deficiency, and indeed like TheUk420Show said a cal/mag deficiency. Look at your npk ratio, maybe there is not enough nitrogen in it. In this stage you have to give around 4% N, 8% P, 10% K and cal mag around 4/3 %. Depends on if you have a sativa or indica, indica needs more nitrogen than a sativa.

First of all its nitrogen and then after that its cal mag they are the most likely suspects i would up your grow feed and then see how you go in a week or so she should strip the yellow leaves and build fresh sets :) prob be the last at that far along in flower :) best of luck for finishing the run :) 👊

Old/Bottom leaves is dying off at the edge ?So these are the oldest leaves my plant has, the rest is fine.The edges are dying off and i don't know why, can anyone help ? The Edges aren't really crispy/dry. Is it maybe too much wind ( Windburn ) ? The Plant is receiving a slight breeze and the leaves are all shaking a bit.

LEAF DROOP: How much droop is normal between watering?Some of my Cinderella99s are droopy. Based on touching the soil, I would wait another day to water, but the leaves say otherwise. What do you think about this?

Am I overwatering these seedlings? (Coco Coir) Please help, Thank you :)These seedlings are about 3 weeks old in Coco coir. I PH the water to 5.8-6.2 everytime. I was watering every 1-2 days as the top soil dried out. Have I been overwatering? How much/often should I water them at this stage and should I wait for them to perk up before transplant?

Yellowing Leaves, Red Stems, Brown patches.pH is correct - run off ph, too. These are 2 out of 4 plants who show these signs. I gave less Flowering Nut in fear of giving too much Nitrogen. Cal/Mag is in use. Is it Phosphorus/Potassium def? I just flushed and gave BioFlores in recommended dosage again. Thoughts?

Bottom leaves yellowing at beginning of flower So my plants have been flowering for about a week now and the lower fan leaves are yellowing with brown spots. Should I be feeding them more of the flower girl I’m using or is this a deficiency of a specific nutrient? (following dr earth feeding schedule designed for cannabis)

Slow growth yellow leaf edges what to do?Plant growing slowly (but still growing) with weak growth tips and yellow edges on leaves with interveinal chlorosis. Looks like overwatering / magnesium deficiency to me. I use a weighing scale to know when to water, but started the plant in 25L pot so this might have caused it.

Yellow parts on very young leaves She's only 2 weeks old and some leaves started yellowing. Should I be concerned or it's a normal thing? Watered her a few times with distilled water (no nutes). Also, there is about 30-40cm distance between the plant and the light (SF1000, put on ~50 power)
