Northern Light Automatic (RQS)

Yeah you're giving her a sweet tooth brother. Definitely drop the sugar for now.

plain water for 7-10 days ( at least few watering cycles ) or just transplant her into bigger pot, then just plain watering again, but your plant will recover way faster. yes its nitrogen toxicity. but far wrom heavy or worst , only bacterias or root stimulators should be given to her , soil has plenty of goodies for such small plant still.

Take some days with water and add a little more humidity. It's abit to low at this stage, so it means that the vpd is Abit high and they take up more nutrients from the soil. But sometimes to much nitrogen extend the veg. periode. So hopefully nothing to worry about if you fix it. 🤛

Last resort , if you are brave and smart, wait till she dries out, transplant her into 3 times bigger house ( not less ) with fresh soil. Water her. No feeding for 3 weeks and she should recover. So only plain, phed water when needed !!! Not everyone will agree, but it works in soil with big screw ups.

pic #3 is an optical illusion due to grow lights, i think... the swollen interveinal areas i bet are a solid green color despite what teh pictures show? look in normal light if you can. the paling tip in from bottom up is probablay nitrogen related. as it progresses you do get those necrotic spots later on too. Pic #4 definitely shows some interveinal and dead spots, which could be Mg-def related. As others said, pH and concentration of other nutes can all impact availability, even if it is physicall present. Eliminate that stuff, then flip a coin as to how you wantn to attack it.. take notes; see what happens. Learn a bit to make the next time easier. Don't do 1 thing, flip-flop and do a different thing before you see the actual impact of the change. it'll be better for your learning curve in the long-run if you do. When you run around like a chicken with its head cutoff it's hard to figure out what was done that actually worked.

Are you keeping your pH in check?

do you have any custom ad blocking filters? if you cannot see "select as answer" while logged in and looking at one of your questions, then it is being blocked/hidden by something.
