We started out doing great. High humidity (75-80%) temperature around 75. Plants loved it.
Turned on carbon filter exhaust fan setup and humidity dropped to 40% and my plants started wilting. Got a humidifier so for the past week it's been 75% humidity around 75 degrees. Plants won't come...
Here's the problem:
My plants were doing GREAT at a high humidity (80%) on accident it lowered to about 50%-60% and now my plants either had a deficiency before this and it's just making it worse or Im not sure. All the plants (2 strains) are exhibiting yellowing on all/most the lower leaves...
Is this a phosphorous deficiency? That's what I'm thinking based on charts? Transplanted a few days ago and overall plant looks fine and is growing like crazy. Anything I need to do?
Also last pic I think is normal plant growth, my husband thinks it looks yellow. Thoughts?
New to all this so...
