Going into week 9 with a 5×5 with 6 autoflowers from Royal Queen seeds and am noticing leave discoloration. 2 plants 2 different discoloration at first I thought potassium then I thought well this one looks like nitrogen but I was in flower, lol idk for sure, first experience with autoflowers but it’s been pretty chill. I keep temps 77-82f humidity 50-60%. For night temps I add a heater bc when light goes out will keep 70-72 with heater while allowing to also lower humidity down to around 45% at night. If I don’t use the heater at night tent get down to upper 50s low60s and my humidity will sky rocket to like 70% even running my exhaust low speeds and having my intake placed in front of the heater did nothing also really. Anyways let’s get back to topic here 3 plant leaves started from bottom up lighter green with speckles of brown. I thought potassium so did my friend who works as a cultivator at revolution. The leaves continued to get lighter and lighter until yellow and fell. Now I did leave em dry back for about 6 hours and they’re in flower which I heard isn’t great now but i thought I was doing no harm. but thought okay it’s gotta be starving then bc it’s getting underwatered and lacking nutes so at least now I need to be on point of pH water and temp of water I should be able to correct. So far it just continues not spreading to but the leaves that already started just continue where I can pull em off easy. I am also having a plant that yellowing but with brown splotches also dying. One plant it’s been doing this for 2 weeks still hasn’t made it to the top but one that short n stocky it just started 3 days ago and already to top leaves being affected. Kinda thought was wild. I put these seeds directly into soil 12/8/2023 and popped 12/11/23. They’re under a roie720.
