any tips are much appreciated!!

I have 3 plants that I started from seeds in starter plugs and transplanted into these 1/2 gal containers. I used some high quality potting soil from the hydro store with little nutrients in it. I started feeding it with some GH flora series at about 2ml of flora grow and flora micro per gal and haven't really seen a change.

I don't have a humidity meter but could this be caused by low humidity?

Soil is VermiSoil Premium Potting Soil 0.8 - 0.5 - 0.3
I feed once a week with GH flora series and water once between feedings with straight RO water

almost looks like a toxicity but the leaves arent really dark green.....hmmmm..

more details on your soil and feeding schedule would be of great help

PH
how often are you feeding
soil brand

humidity isnt going to cause leaf problems like that, high humidity will invite mold....what strain? could be a ultra nutrient sensitive strain. really hard to tell what the exact issue is without more details.

I hadn't been able to check the ph of the runoff so I had just been PHing the nutrient solution to 6.5.
It took 12 days to germinate and sprout the seeds in starter plugs feeding only with water.
I have been feeding once a week and watering once in between feedings with RO water
Soil is Vermicrop Premium potting soil 0.8 - 0.5 - 0.3

this is what I thought too, but this happened before I ever starting giving it nutes. I transplanted my starter plugs from seed into the 1/2 gal containers when they were 10 days old and only fed it tap water until they were about 18 days old. Then I started feeding with the GH flora nutes for 2 weeks and they grew very little and the symptoms continued.

They are now 34 days old, not looking very big for that length of time. Just trying to get one big enough to take 4 healthy clones since each bucket is a diff strain.

my grow journal is here https://www.rollitup.org/grow-journals/615218-led-closet-grow-blue-cheese.html
