So i have been working on my first ever grow. Am growing her in a 2x2x4 MarsHydro tent with a ts1000 LED and started to notice she is turning yellow and has a lot of red in her stems. Am using Fox Farms nutes Dirty Dozen box set. Have started feeding using week 2 schedule as she had already been topped a couple times and started LST. But I started noticing she is very droopy and turning very yellow. Had lights at 100% about 26" from light in total in a 3gal pot. not sure what i need to do to help bounce her back from here. Any help is appreciated.

Welcome to the community ! What kind of soil are you using ? leaf droop can Can occur from overwatering or underwater. Also lights on to lights off. Have you checked PPM runoff ?
So I have only watered max 1/4 gal every third day. Maybe a little sooner. Drive finger in two knuckles to feel for moisture am using ocean Forrest soil with an extra 3 cups of perlite added for better drainage and a lite layer of gravel on bottom of pot as well to avoid root rot. Ph of run off was about 6.8 last check and clean water ph is 6.02 with epsom salt added. Feeding ph is at 6.02 as well with yes of 1580 and ec of 2.28. Which are both in zone per feeding schedule sent with fox farms.

Also lighting schedule is 18/6 was running at 100% after topping and LST started but turned back to 75% due to coloring hoping was light issue not nutes. Photo I added to last post is from last Wednesday when I topped her and started LST.

Last picture overall she looks good , plant color much better than the 1st picture. Ocean forest soil is pretty good to carry a plant 6 to 7 weeks before feeding.

75% on light should be good through veg stage. Reddish purplish stems that is normal with a lot of strains .Keep us posted she will start filling out soon.

so did her first watering since feed and her soil run off PH is 7.34. also out of tent lights she had a much darker green to her than in photos and so hoping it was just a lot of stress from topping two branches and starting LST. fingers crossed…

First pic is her natural light right as lights turned off for night. . Next 3 pics are my reads after flushing her today and last pic is her last night at lights on when i watered her and her run off tested at 7.43. so like i said i ended up flushing her because i felt that her run off at 7.43 was going to hurt more in the long run so after turning light down before they came on yesterday and to today her color got a bit better but felt she was locked out. Was curious though on these reads for her run off after flushing using 5.8 ph water to flush with. Normal waterings are about 1/4/-1/3 gal so mixed a gal of water at 5.8ph and fed it through until gone. Caught tail ends of run off into a new solo cup and these were the reads i received.
