One plant out of my 7 is showing some sort of deficiency. Here are the details:
Medium: Fox Farm OF
5 gal fabric pot
Spider Farm 4000 led on 70% 18” above canopy
Feeding once weekly ph 6.5-6.8 FF Trio plus calmag/ PPM per feed is 1600 or so.
Soil runoff Ph stable at 6.75
Watering once (besides feed) a week when top 1” soil is dry (ph 6.7 water)
Week 5 of Veg
Temp 75 Rh 68%
Strain: unknown (hybrid)
Full AC infinity in line fan, two small circulating fans.
Top and bottom growth looks ok- it’s a few leaves in the middle. Plants did have a MAG deficiency but corrected and healthy since. These leaves have changed slightly since then. There is only about 4/5 leaves showing this and the photo attached is the worst one. No other plants show any similar signs (5 of my other plants are in organic dirt- this is one of the two in the FFOF, the other FFOF plants is much better- maybe a tiny bit of the same problem but not like this one).
Will upload more images if needed just didn’t want to not be able to blow this one up so you can see close up.
