started grow question 6y ago
Nute burn? Thrips? Some of those leaves where tucked aggressively at one point. I'm leaning towards nute burn. Think I over did it a little.

Same spot on an outdoor plant I have but I know that mine was caused by the temp dropping down to 0 the other night. Fricking middle of june and weather going down to frickin freezing. Global chilling. That will be the new tax grab...

Yellowing of top fan leaves
What is causing yellowing of the top fan leaves? Started to happen to a plant that I broke by accident during LST. However around the same time I upped to 2ml/l and moved the light a little closer. My ph has also been high (fine now). No idea which one could be the culprit

Lock out or lack of nutrients ?
I am having trouble identifying if this is a lockout or lack of nutrients. I was told to stop flora micro. I have been giving 50% strength of what the bottle suggests. My other plant same tent just had a lockout and I flushed.

Leaves losing "color"/turning yellow-ish. (autopot without nutes)
I've been using autopot system wihtout nutrients, plants now went to bloom. Could the smallest of the bunch (NorthenLight left down corner) have some defiency? As others are not "complaining", at least yet. Should purchase nutes that work with my autopot, only biobizz left now.

Soft hanging yellow leaves, some with brown spots in the middle. Deficiency, Nutrient Burn or what could cause this ?
Hey guys, I got a problem with two of my 4 plants. They started to develop yellow droopy and soft leaves that start to fall off on their own. I’m not sure if it’s a nutrient deficiency or blockout from ph or something else. I watered them only with water ph 6.5.

Yellow Leaf Tips with Brown Spots – What Could This Be?
One of my plants has yellowing tips on some of its leaves, and there are also brown spots forming on these yellow areas. Any ideas on what could be causing this? Could it be a nutrient issue, or is it maybe related to pests or environmental factors?
