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.'

Yellowing on GT and clawing on CB I'm seeing an issue with Ghost Toof. The lower leaves are burning it seems. It looks like it could be a K(Potassium) issue, or possibly nutrient burn. Also, Chem Bear seems to claw quite a bit. I don't think I'm overwatering... so maybe a Nitrogen issue?

Deficiency or Nute Lock?I was a told a week prior I was feeling too much. So I stopped. I left town for 4 days and came home to the current photos. One looks like nitrogen deficiency, the other looks like calcium deficiency except I've fed 1tsp of tiger bloom, .5tsp of Cal-Mag and big bloom last week.

Help, what are those weird yellow spots in late veg?Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid. Checked the whole bud, but no insects. My other ideas are mold or stress from the light?

Plant seems to be dying, should I flush? And if so, any tips?Yellowing & wilting, I suspect the problem is too much silica boost .5ml every other water, combined w/ hot soil (FFOC) & a few feedings, & maybe underwatering(?) as I never have runoff, watered a cup or so every ~48hrs, when soil had dried. LST, no wild temps/hum, great airflow.
