Purp stalks, weak leaves.
williamrainx37started grow question 5y ago
Hey guys i noticed that my stalks were all turning purple and my leaves are curling. Is this a nute lock out ? Or is it light burn ? I started them under a pretty powerful Led but still getting new growth through the last 2 days. They look thirsty but medium is still soaked.

well, if new lights are much stonger, the wilt could be from that, but not likely the purple petioles.
the purple can be from stress but also a P-deficiency. often happens with LED, i believe. could also be genetic and perfectly fine. can try adjusting ratios a bit and see if a little extra P helps or hurts.
since soil is soaked, i bet it's the new lights making it cower a bit. they'll handle more with a bigger root system and canopy.

The red on the stems is the plant trying to protect its self from the sun. I'd say you could move that light up a bit. And they look a bit overwatered. Wait untill your medium dries out a bit more before watering again. Cheers and happy growing!

What deficiency is this ?What is happening to my plant right now ?
I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks.
Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil.

Leaf discoloration. 5 weeks oldI transplanted these girls 2 days ago and have started them on a new nutrition. I’ve noticed some discoloration on one of the leaves today almost sure it’s the nutrients. Can someone help me figure the best thing to feed my plants? Thank you (nutrition diagram on my first diary)

Anyone know what’s wrong with my plant? Has had marble Colour effect on the leaves since it was a seedling and is now wilting. I’m debating if I should remove it if it won’t flower properly. To allow the other plants more room to grow as this is only a 750x750mm tent with 4 autos
