All newborn leaves are turning too much yellow

eduard_shevardnadzestarted grow question 4y ago

All newborn leaves are too much yellow. Do you have any idea what problem could be? 7-10 days ago turned to 12/12 for bloom phase. I think its light burn, BUT even lower newborn leaves are yellow.

Your ph is out check your runoff. Your plant could be stressed. Also looks like you have an iron deficiency. If it was light burn your lower new growth wouldn't be yellow also.

Early stage magnesium defficiency. Iron defficiency can also cause new growth to yellow. You need to find out if it is defficiency or caused by lockout of either incorrect ph or to high ec. If both these are proper then it would be defficiency. Cheers

Leave spotting Nute burn? Thrips? Some of those leaves where tucked aggressively at one point. I'm leaning towards nute burn. Think I over did it a little.

Strange Bud Formation A Girl Scout Cookie has normal growing dense buds but also has deformed buds on two branches where they are stacking weird and are light and wispy. What is this? Could it be from having nitrogen toxicity in the flowering period?

Time to flush?If I want to flush for 5-6 days (coco), and rn I have 90-100% cloudy on the buds, 90% cloudy 10% amber on sugar leaves, and some foxtailing on tops of some colas, should I start flushing right now or wait a few days? (I'd like to harvest with amber 0-10% on buds).
