Flipped into flower and found this day 2. Humidity is 50%, ppfd is 400, ph is 5.8, rm temp is 78. I use Athena blended fed using trol master and Dab pump. No issues until I Flipped into flower
Growing in coco. Mother Earth with perlite. Using a drip feed system.looks like could be a couple things though what medium you growing with?
ok, not my area of greatness haha, i agree with above as light stress/burn but i feel something else is wrong too,Growing in coco. Mother Earth with perlite. Using a drip feed system.
I'm using Fluence Spydr 2i lights. Decent distance from the plants. I'll dial them back a bit. Right my meter says 400umol at roughly 2 ft from the tops. Trol master set at 25% which normally works with past grows. Thanks you for taking the time to look at this.Thats light burn, my friend
Thank youok, not my area of greatness haha, i agree with above as light stress/burn but i feel something else is wrong too,
i’ll tag @Aqua Man as he’s a master with coco and he’ll be able to get you on the right path quickly..
so wait for him to reply..
back off the lights in the mean time or set the plant/s further away..
I scope the plants weekly with a 100x Dino scope. No bugs. Inuse Athena Blended line. I mix cal mag first, bloom A the B. Ph I feed at is 5.8. Humidity is controlled using a quest unit...The drip system is set to feed every hour for 1m. I use a Dab pump with trol master controls. AquaX/hydroX. Pot size is the flora flex 2 gal pots... In veg the plants looked great. Lights were off for 24hrs, Flipped to 12/12 then almost right away this started happening. I've grown for almost 5 years and never had anything like this in the past. The room is completely sealed with no exposure to pets, people etc. I even shower before entering my room everytime.You have root issues… could be rot, ph issues, pest damage and likely watering is an issue.
As @GNick55 said back the light off because when plants are sick they tolerate less light and giving them more than they can hadle when they are not healthy will only make your issues worse faster.
Scope the media for gnats or root aphids and inspect the leaves for mites… to see russet mites you will need a scope they are very tiny and for root aphids too.
Can you explain how much of what your mixing and in what order?
List all nutrients and additives used including ph adjusters
The ph your feeding?
How often and how much you are feeding?
The pot size?
Ok need to be more specific how much volume wise is 1min and how much run off?I scope the plants weekly with a 100x Dino scope. No bugs. Inuse Athena Blended line. I mix cal mag first, bloom A the B.

Mother earth with perlite is what i use, inl use RO water and need to use ph up after mixing nutrients in my rez. I use advance nutrients ph up and down. Ppm in week one flower is 650. I use athena light feeding schedule. In past grows it has worked well with little to no tip burn. I would have measure the volume when the lights come on tonight to get you an exact amount. Small amount of run off. Volume of runoff is unknown.Ok need to be more specific how much volume wise is 1min and how much run off?
What brand of coco? Is there any perlite?
What brand of ph down?
What ppm of nutrients?
What is the ph and ppm of runoff? This will tell alot.Mother earth with perlite is what i use, inl use RO water and need to use ph up after mixing nutrients in my rez.

Thank you. I really appreciate you taking time to help me out. I will post my ppm and ph runoff tonight when the lights come back on.What is the ph and ppm of runoff? This will tell alot.
The ph sounds like it maybe unstable.
Use the PH up first then nutrients and finally ph down last. You should be establishing a stable ph using a buffer and ph up can be used as a buffer. You dont want to use a PH down with the source of acid being citric acid as that reacts with bicarbonate and off gasses as co2 cause large ph swings from whats going in to the root zone and whats coming out

Marijuana pH Levels for Growing Weed: A Basic Explanation
OK I'm going to do my best to explain PH since its something that is for the most part greatly misunderstood and can be confusing to new growers and even experienced growers alike. This will explain why we need both ppm and PH meters to give us informed information about PH This will be a...www.thcfarmer.com
