Plants Wilting / Red Stem (HELP ME)

[KeytheCaregiver]

More plant problems!

Just transitioned plants from their veg room (considerably smaller than flower rooms) to their flower rooms. They went from being under T5’ to Gavita 1930e Full Spectrum LEDs. This is the second time we’ve transitioned since these lights were installed and the first time we burnt our plants. Trying to avoid this, we turned lights to 50% and are keeping them in their veg cycle (18/6) until their condition improves.

Room conditions

Course of events
Day1. Plants are moved onto their respected tables roughly 2’ from the ground, and 8-9’ from the lights.
All plants are dark green.

Day2. Plants are watered with 6.0 pH water , mosquito bites, and powerSi (low dose, preventative for fungus gnats as we live in a forested area that promotes their growth)
Plants are still green.

Day3. Plant’s stems start turning red. Some start to show signs of wilting.
RH was low (40-42%)
Added a humidifier to room (doesn’t do much though)

Day4. Plants are dry again, watered with 6.0pH
Red stems become more consistent throughout rooms. Select few plants wilting. Pictures below

Day5. Off day

Day6. All plants that were under T5 lights during veg have red stems and select few are wilting. Pictures below

We have not fed these plants due their EC being at 1.9 during our latest runoff test.

Light stress for sure when you go from a T5 to LED at 10inches that'll happen.. That probably coupled with rootbound and something else. How big is your room? What Medium?

Rooms are roughly 500sq ft

Grow Medium
Happy Frog soil, during Veg then we transplant to a Soil/Coco/Perlite mix

geez why would you set up such a large grow and can’t get through the basics, and IM NOT BEING MEAN..
just saying.. few things going on, firstly lots of those need to be transplanted,..

Wait so when was the last time u transplanted? And what was the pots that you used

We can get through the basics my man, not going to transplant dying plants.

We use 9"x 9" plastic pots, and we normally transplant before we move them into their flower room but these ladies needed to be hardened off to the Gavita 1930e'. We veg under these for a while until we see them come out of light shock then transplant.


Unfortunately we have figured out the root cause of this problem and it is ROOT APHIDS.
