answered grow question 6y ago
Hi Mate, It seems to me an initial K deficiency. Also I have noticed the edges of the serrated leaves begin to curl up as heat/overwater stress. I think that only little corrections are needed, she is quite healthy. IMO 🤞

Plants react to darkness in different way
During the night, I have noticed that 2 plants out of 3 stand with normal leaves straight, while 1 has leaves going down during the darkness and when the sun rises, it gets back to normal. They are all same strain, grown in same way, why?

Can you get two plants from one seed?
What is this little surprise? Do I have another viable plant or is this just a cotyledon? Also, when transplanting, do I bury the existing cotyledon on the stalk? Thanks!

I am looking for some advice on the yellow spots on the first set of real leaves. I just raised the light to 30 inches and turned it down from a quarter to an 1/8th Mars Hydro TSW 2000. Thank you for looking.

Will plants with Nitrogen toxicity go back to normal green color after they recover.
Will plants that have turned dark green with clawed leaves from nitrogen toxicity turn back to a normal green color and the leaves straighten out or will it stay like this? I flushed her Jan 2 and watered her again on 1/9. She hasn't started growing yet and still dark clawed

The ladies are telling me something but I'm no weed-whisperer yet so I'm gonna need help. They are now 3 weeks since germination and I've only been watering them once a day with a spray. No nutrients yet. I have a 3-2-5 nutrient for Herbs & Tomatos but maybe only while flowering?

Red Stems on the fan-leaves!!
What is causing the RED stems on the fan-leaves of my plant. The Blue God is in week 3 of Flower. 2 other plants are getting the same diet and light and the B.G. is the only plant with red stems. How do you tell if it’s a deficiency or over-feeding? How can I turn this around?
