Full top canopy of plant(s) turning yellow

justazedstarted grow question 4y ago
Does anyone know what might make fan leaves turn yellow while having dead/burnt tips? the two at the front are the same plants (i think) and they have stark differences in colour, maybe light bleaching since the lower canopy is still much greener?

As your diary is only one week it's hard to judge where you may have gone wrong. My judgement is on the pictures really, and I would say they need a little more magnesium. If you was using a cal mag product leading up to the problem and stopped using it before problem started then I would be tempted to start using it again. If not either use one or look at your flowering products and increase the product with the most magnesium in.

Chlorophyll degrades below 67 I think, but roots will no longer uptake manganese below 64 and will hinder bud growth, Night temp should not dip below 67 otherwise it slows growth in general, generally applied later in flowering the cold triggers hormonal ripening. very little information is filled out on your grow which makes it hard to diagnose, where are you measuring temperature in your tent? make sure top of canopy does not exceed 86 with lights on as trichomes degrade above 86.
