Yellow bright new growth

herbalistsswordstarted grow question 5y ago

New leaves on the Candy Kush plant #1 are bright green/yellow. This seems to have started when increased biogrow from 2ml/l to 3ml/l. Iron, zinc or sulphur deficiency? Only give calmag on next feed? Might have measured pH before adding nutrients so Faber wrong pH?

Yellow blemishes 1 week old seedling is starting to develop yellow blemishes on initial leaves. Soil is biobizz lightmix, PH 6.2 from bottled water with no nutes, 150w led light is at 50% and 25-30cm distance. Is it a cal-mag deficiency, light burn, genetics, or just too soon to worry?

Yellowing continues Leaf yellowing continues, is it normal as it’s already the end of the flowering for them ? Can this still be influenced? Previous advice was to raise ph and give N. Yellowing still goes, flushed them today, one yellowing plant was giving ec 1,7.

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.
