I have a single irregular shaped yellow spot on just one leaf on one 15 day old plant. I want to assume that somehow I may have dripped some water on the leaf, but I have not done any foliar spraying yet. This is my first grow and they are due for a feeding of some grow big in their next watering. anyone have any input as to what the yellow spot could be?
My hygrometer/thermometer reads the daytime temps hitting 77-79F(for the past few days it has only gotten to 77.) and the rh is 43-53% It seems to be it's lowest during the on cycle, I am not awake during the off cycle, so I assume that is when the humidity is higher.
My plants are a Short Stuff mix that are 12 to 13 days old. My plants are in a 4x4x6.5 foot grow tent with a 240cfm fan pulling air out through the light. The light is an air cooled 400w HPS 30" above the soil so about 27" above the canopy.. They were all watered 9 days ago with some water at 6.8, the runoff was 6.3 soil = 5.9? This is the only plant doing this to the extreme. There are 2 desk fans circulating air inside The planters feel good for weight (4gallon) the soil is ProMix BX. I have not fed any nutes yet, but I have Fox Farm Trio on hand. I have city water and it always sits for at least 24hrs uncovered with an airstone in it. The last time they were fed the water had been bubbling for over a week. I have a digital pH tester with calibration fluid. The first time I fed them I used distilled white vinegar to reduce the pH, the last time I used pH down from the hydro store. I have never sprayed the plants with pH water.
If you need any more info please don't hesitate to ask
Thanks for the help!
Sorry about copying and pasting the info from a previous thread. The info is still relevant as to the description of my grow area and such. Their age today is 15 days.
