Yeah depending on your soil and how much is in there but yeah it seems your plant is starting to get hungry. It’s normal in flowering.
Good luck 🤙

Yeah it kinda does look like the beginning stages of potassium/phosphorus def.
Your plant is probably transitioning to flower. So just start feeding some bloom nutrients at a balanced PH for your medium and it should be fine. I mean affected leaves will stay as they are but they shouldn’t get worse.
Hood luck friend your plant is looking great. 🤙

Deficiency?Hey everybody,
I’ve never really dealt with deficiencies in autos as most of my experience is with growing photos outdoors.
Does this look like a magnesium deficiency? These just appeared over night on just two of my larger growing white widow autos.
Please let me know, thanks!

Odd leaf bitten?Hi All,
Noticed the odd leaf like this that looks like something has taken a bite of it.
It is only the odd leaf. I had some fungus gnats a few weeks ago which are now gone.
Is there something else doing this and do I need to act?
Thanks

Is this light burn?I am pretty sure it is led light scald but just thought id try to verify. I have a new 650w Hortibloom light bar and have been running it between 400w and 650w at the top of the tent.
I'm guessing 650w, even at the top... is too much?
They are in soil, and I'm using gaia green

Cal/mag problem or heat issue?A few leaves have some problem spots popping up here in week 6 (see pics). No nutes, PH’d water. FFOF/HF/Perlite mix for medium under 20 hours of light. I’m guessing either got too hot from being in 90F heat for an hour or needs cal/mag? Any advice from any veterans out there?

Hey all, so my pistils have had discolored and some dry/shriviled looking tips for a few weeks now. This seems a bit premature to me. You can notice in the 7th pic this week and several the weeks before. Has anyone experienced this, otherwise any possible ideas it could be?ThanksWeek 20

Getting out of the ideas - VPD, nutrients or deficiency?I'm getting out of the ideas as the foliar symptoms proceed.
Lowered EC down to 1.8 from 2.2, pH in range.
VPD is getting problematic as the plants seem to be respirating a lot during the day and it rises tent RH sometimes up to 70% - exhaust duct fan wont keep up. Temps 22-24C

Yellowing, burnt tips and edgesHello fellow growers I noticed this happening rapidly after I top dressed. What kind of deficiency is this? Is this nutrient burn as well as a deficiency? Solely a Ph problem?. So far I’ve come up with maybe potassium deficiency and improper Ph when watering? Please help

Did I do the right thing? Pls check my update on this week!Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.
