recent ph problem, but more yellowing?
I had recently put my 2 barneys farm lsds and 2 g13s outdoor after having them grow on 24 hour light indoor. Everything has been fine and they are looking good except one of the g13s. I had a slight ph problem, but fixed it with lime and new growth was fine a week before I brought them outside.. now the g13 has yellowing on its big fan leaves.
If anyone can tell me what kind of deficiency that looks like Id much appreciate it=0
Are they dr greenthumbs g13?
Well it looks like heat stress or light bleaching. How close are the lights and what are the temps?
Try this on for size.
Nitrogen or Sulphur.
Also yea maybe heat stress.
No light bleach.
They were under a 600watt mh for about a month, but last week I moved them outdoor, I let the soil dry out(maybe a little bit too long) but watered yesterday early in the morning. It got up to 95 degrees so maybe its heat stress? if so why is this one plant the only one doing this when I have 3 others out with it. they have all been in the same environments since they sprouted
they are also still in 1 gallon pots but I am transferring tomorrow to a 50/50 promix and ffof mixture and planting in ground.they are currently in a 60% coir and 40% ffof mix.
wouldn't the ffof cover the sulpher needed? and I am also using fox farm nutes
and Nice ol bud..... what month of growth were those plants in your picture in? cuz I'm hoping to have mine get as big as that!!
They aren't mine
