Let me start off by saying that all I do is clones, so asking for insight can be humbling haha.
I used to run Grodan 1.5" cubes in a 10x20" tray. 72 per tray 6x12. I was having issues with leaves yellowing between the veins and the leaves shrinking with burnt tips. I thought maybe the cubes where too close together and unable to dry out properly so I switched to the Grodan 78 cell smart trays. Those also have a spacer to keep the keep the cubes off of the bottom of the tray, that was a big green light for me since the lights from the shelf below are within 1/2" of the bottom of the tray above.
Clones are coming from lush deficient free moms and go into the trays looking perfect and do look perfect for the first few days.
-Cubes are soaked in Azos (2tbs/5gal) for at least 12 hrs (these new macro plugs start to break up at 24hrs) in 5.4-5.5 water, the water is 24hr water from tap, kind of hard coming out at 7.1.
-Everything is sterile, Razors, scissors, working surfaces are bleached
-The cubes are shaken of excess water before being placed in smart trays
-When the dome is placed on new cuttings, the vents stay shut for 2 days, then open for 2 days.
Clones get watered on day 4 , then the dome comes off. The issue is if I leave the domes on, vents closed, the leaves start to turn black like there's too much humidity. But when I open the vents after day 2 they start to yellow in between the veins, get burnt tips and start to look like absolute shit. After the leaving the dome off for a couple of weeks the clones (70-80% of them) come out of it and go back to looking great.
I want them to look perfect all the way through. I understand a little yellowing when they take root but this is pretty terrible.
ENVIRONMENT ENVIRONMENT ENVIRONMENT
- Root zone temps are about 77-80
-Root zone humidity is about 30-40%
-Lighting is 2 4' nanotech single T-5s per shelf
-Feeding is a simple 1 part Dyna-Gro PH'ed at 5.7-5.9 with a Benny feeding once a week when I do my moms.
-When we water we take the domes off the younger stuff to let them breathe for 5-10 minutes but don't water them.
-We have like 10-15 different strains, some are easier than others but this issues effects even the easy stuff (C99 <3).
Any help or insight is soo much appreciated. The main help I'm looking for is within the first 7 days. Thank you.
