Yellowing in the top?

jkadabrastarted grow question 6y ago

What's with the yellowing in the top? Is it normal? It's in a very nice soil mixture and I've fertilized it with Osmocote, a popular slow release fertilizer: https://icl-sf.com/mx-es/products/ornamental_horticulture/osmocote-plus-standard-5-6-a903226-15-9-12/

"Symptoms" look like trace element related issues, but in soil that'd be rare. So, check pH of soil. I bet it is low or high. make sure you stick to good watering habits too. Get it to 6.5-6.8. pH up or down anything you put into soil to that range. Next irrigation give it a good run through make sure oyu get >20% runoff - toss it out or outside somewhere useful. Always water until 20% runs out bottom. Always wait for top 1" to dry - or get familiar with the weight of 'dry.'

Cal-Mag and N Deficiency in Flower? Thanks!I'm guessing the yellowing and brown spots (in Wk 8 pics) are related to Cal/Mag and maybe a lack of N? Would love some advice from someone who's seen this before Thanks! I'm seeing this in all my grows to some degree- using FF trio and FFOF but not for much longer

Leave's tips color turning yellow Hey everyone, for the past 2 days I've noticed that the tips of the leaves are turning yellow. I thought about moving the light away from the girls, even though I'm using an LED (marshydro ts1000). Can you tell me what I'm doing wrong? Should I also adjust the amount of nutrients?

Help calcium deficiency I think I have a bad case of calcium deficiency? This started shortly after switched to 12/12. I added 1/4 tsp to a liter of water 2 days ago. I’m not seeing improvement. Am I right ? Will the leaves turn back green (how long)? Is it something else? Will it die?

Auto flowering, PH is 5.8 to 6.1 every day. Hydro set up. Botanicare grow, calmag, and hydroguard all given half the regular amount.Finishing up second transition week. The bottom leaves started turning a little yellow but are now turning a lot more yellow. Assuming this is the plant just using it's own nutrients stored in the lower leaves. Any input? It's a hydro set up. Thank you everyone.
