I havn't watered since Tuesday and I'm Promix HP which is supposed to have fabulous drainage! Bottom of the pots are still a little wet though. Lights are up at 24" from canopy. The TO Cookies plant was very droopy yesterday. I recognized the symptoms from the first time I let them all dry out after transplant so I did give it 1L of water, just enough for some surface moisture but not enough to get to the bottom where it was still wet and it perked right up an hour later.
On the upside all the leaves seem to look healthier in colour as in a no more light green or magnesium deficiency signs since adding Calmag. Growth is starting to pick back up again I just need to sort out watering. I don't think they have the root systems yet to really drink up a full pot worth of watering so when I fully water everytime the bottoms are just constantly soaking wet.
After reading some of Emily's stuff I think I need to flush to start fresh and then lightly water the tops like I did yesterday intermediately until the bottom of the pots dry out and then fully water. until the roots grow enough to return to only full watering. Also going to cut nutes in half.
Attached before and after 1L of water for TO Cookies.
