What deficiency is this ?

LetsGrooowstarted grow question 4y ago

Anyone know what deficiency this is? All 3 plants that are flowering have the same issue. Seems to be interveinal chlorosis that is starting from new leaves at top going down. They are 40 days old.

They say that when you get a deficiency at the beginning of flower, it could be a potassium deficiency. That usually affects older leaves first though. Is your light too close? Cuz yellowing tips can be light burn. Light burn and potassium deficiency look a lot alike. Hope that helped.

They may need extra cal-mag from now on. I noticed mine had the same issue when started to flower. Also in early flower you can still feed them with grow nutrients to make sure they still have nitrogen to develop.

You may have cut out the nitrogen to quickly. They still need some at the start of flower.

Yellow streaks between leaf veins All three of my plants have light green/yellow streaks in between the veins on the leaves that have been present since about week one (week 3 currently). Could this be a magnesium nutrient deficiency, PH issue, or perhaps just overwatering?

Please help identify the cause, interveinal chlorosis since 2 weeks old, no necrosis so far. These two plants are 26 days old. Do they look stunned?Is this magnesium def since it's going from the bottom? Is it possible the first signs started to show when they were just 2 weeks old? Or is this iron? Or is it smth else? Calmag given two days ago. Pistils show already. I water with ph6.2 but no runoff yet to know the soil ph.

Leaf issue What seems to be the issue with older and new leaf growth here? It looks like cal-mag or potassium deficiency in my opinion, but I’m not really sure.

Leaves growing differently, some of them with more difficulty Why some of the largest leaves look like they laterally grow smaller and with some different shades of green? There's a lighter shade between the veins and darker spots, meaning that they are actually still growing? thank you in advance :)

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flower The odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

Leaf fade vs. deficiency Hey everyone, does this look like a deficiency? I’m in week 6 of flower, I had half a week of high temperatures and I’m sure she was affected just a bit and noticed Bud growth slowed slightly. Not sure that influenced this and if it’s a deficiency(magnesium?) or normal leaf fade.
