I found a few of these on the bottom of the plant today. They’re on the very bottom secondary shoots, pretty small leaves, maybe 2 inches across at most. I think there have been a few more over the past couple weeks, they’ll end up losing their color. Not sure if I should up the advanced nutrients calmag plus…they just had a full strength dose(had been increasing gradually since mid January) yesterday so I’m not doing anything right away. Curious to see what you guys think. It should be easier to diagnose now that most of the notes are on this page.
Soil in pots, Hydroponic, or Coco?
Soil, ffof/happy frog to start(1 gal), then transplanted to 2 gallon with MG organic(mistake, had problems) so transplanted again to 3 gallon smart pot with promix bx, and one more time to a 7 gal fabric pot with bx.
With great white myco.
PH of runoff or solution in reservoir?
*The recent deficiency/stunt- I think due to soil ph. Hadn’t checked runoff for a while and it was really low, around 5, maybe even 4.8. So I flushed with ph 7.5 and added organic powdered eggshells to soil. I have always used rain, melted snow, and distilled phd to 6.5. Idk how the soil ph became so low. I was able to get the runoff to 6.5, and the new growth looks better, and the discoloration has stopped, maybe even recovered a bit.
*recent(February 1st)ph was high. It should be all set now.
What is strength of nutrient mix? EC, or TDS
Unfortunately I don’t know the ec or tds, always used 1/4-1/2 strength 5-1-1 fish, earth juice catalyst, 8-2-1 guano tea, and 0-10-0 guano I recently added to the tea, and a little in the soil
- flower: using advanced nutrients calmag plus, and big bud, soon to be using some compost tea, and bs molasses
Indoor or Outdoor
Light system, size?
Started with cfl, added 300w led, and another 300w led
Temps; Day, Night
In flower:72-75, 62-65
Humidity; Day, Night
In flower:D 40-50,N 60-70
Ventilation system; Yes, No, Size
Small fan on top vent hole, pulling air up through the vents
AC, Humidifier, De-humidifier,
Co2; Yes, No
A little, I use 3 separate gallon jugs with yeast/sugar, two other bottles to monitor CO2 output, which is usually 5 bubbles/second. I think output is good, but it’s probably sucked out when I have fan on. Sometimes I seal it up so the CO2 get down to the plant.
