Sup everybody, my plants are showing off some symptoms which to me look like a serious deficency, im in the last day of week four of flowering and everything was going well untill now that the yellowing on the lower leaves is going pretty fast in two of my plants.
Im not sure if is a N, P or Mg deficency so im asking for any experienced growers for more opinions, thanks in advance, here are some pics:
Plant 1) this one barely ia showing signs in one of the leaves so the problem in this one is not so bad, all the other leaves in this plant are green as they can get, but not the lower leaf, I noticed that the yellowing is coming from the sides also, this one doesn't get me too worriedworried because is going slower than the other two plants but here's a pic:
Plant 2) this one was going really well and since two days to now the yellowing took over a few lower leaves and this one has some brown spots like drying in between the leaves:
Picture of another leave same plant
Plant 3) this one was the first to show signs of the deficiency which at the beginning I though it was Nitrogen def, but then I thought I give her some fert with N but still turning yellow in the lower leaves:
Ohh btw, the plants are green and lush on the top leaves but plant 2 & 3 the yellowing is going faster.
Thanks for any advice.
