View attachment 2733566I'm growing World of Seeds afghan kush indoors under some CFL's. This is my first time growing indoors. I usually grow outdoors. It is 10 days old from seed today and is in sub cool's super soil blend with fox farms happy frog as the base soil. My question is it normal for the bottoms of the leaves to be this purple? Is it the strain? Will the buds end up being purple? These are my questions. Just curious that's all. Thank you
Purple Stems could be a result of genetics, if this is the reason, you are to expect a purple stem throughout the life of the plant. It must be noted that purple stems arent a dominant trait, and are rarely genetically induced.
A baby sprout with a purple stem is almost always 100% natural. Young seedlings are still adjusting to their environment and may be slightly lacking in a Nutrient. If this is the case, healthy plants will regain their green/greenish-brown color within a few days to a week or two.
If you have ruled out the possibilities of genetics and the seedlings adjustments to life, you should begin looking for a nutrient deficiency. Purple stems are commonly caused by a Phosphorous (P) or Magnesium deficiency, if there is a P deficiency you may also notice symptoms such as brittle leaves or greyish spots. To assist the uptake of Phosphorous you should ensure the pH is slightly acidic-- 6.0 will suffice.
