Purple branches
cannononestarted grow question 4 years ago
Hey, many of my branches have turned purple, and a few leaves yellow.... I'm using bio grow (biobizz) since 5 days, is it calcium or magnesium deficiency? What to do? And can I start with flowering now?
Thanks

This is very common. Usually turns out to be sunburn, which is completely fine. You can diagnose this by checking the sides of the stems pointed away from the light, if they're still green on the underside, its sunburn. Nothing to worry about.
If the entire stem is red or purple, it could very well need more phosphorus. This is also a common problem.
Less common are genetics, which you should already know if that's the case, and temperature. If the temperature drops to the low 60s at night, this can cause purpling.
I think that covers every base! Good luck!!!

Yellow leaf tips and edgesYellow leaf tips and margins… what do you think? Nute burn? Light stress? Cold stress?
Will this eventually resolve if I leave it alone and let it work itself out? (Which is what I’m inclined to do)
Should I flush my plants or try some other intervention?

Hulkberry turning dry and leafs are bending upHulk berry auto flower leaves turning dry.
Hey, my Hulkberry is not doing so good, I assume this is due to overfeeding it with fertilizer. Right now I just flushed the plant with 6.1 pH water and I'm waiting to see if it helps. What more can I do?

Something bad is going on with my Hulkberry plant. I think it might be due to giving it to much fertilizer.

Living soil growingGrowing in living soil with dry amendments. It’s mid week 6 of flower and lower leaves are showing N/P deficiency. Nutrient teas don’t stop it. Really it has no effect it seems. So Is this supposed to happen at mid week 6? If not how to fix being 3 weeks from harvest?
