Hello new member here, wish there was a forum to go to 40 years ago like this, back then had to rely on trial and error , even now always something new to learn. Running godfather and Chiquita banana, running into some yellowing of lower fan under 300w led full spec , thought maybe running the light at 80% during veg was to much so cut to 50% and plants responded but in 3 week of flower and happening again, did raise to 70% after a week of 12/12 , any thoughts ? Thanks
