Purple branches
cannononestarted grow question 6y 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!!!

Im getting what looks like a Nitrogen deficency but I have put nutrients on my plants and still the same. What other thing can cause this? PH? All strains are 4 to 5 weeks old and already flowering. Yellowing started to show very early, since week 3 and leaves fall off.

Yellowing, curling tips?I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistake3y ago

Yellow blemishes1 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?

Any ideas to what might be causing these leaves to yellow/die? Only reasons I can think of are nutrient lockout, having the lights too close (although I've heard with CFLs theres pretty much no such thing as too close) or possible having the heater running, or constant fan airWeek 3
