I need help diagnosing this problem. TIA

Idk why I put the tsl2000. It's a tsw2000 hahaha

No biggy bro,you running a tight ship so that's the only area I can see that you left any room for error good job bro

Much obliged! My buddy helped me get going with some knowledge. Once I started, I watched/read probably 200 hours of growing tips/research. So I know what I need to do, but the execution is a bit upside down if you will

Looks like a watering issue. My best guess is either you’re not pushing enough runoff which is distorting your pH in the soil or you’re just not feeding them enough which, again, is up in your pH nevertheless, you have a PH problem. Your solution I say is to feed more with more PP.M. Essentially you want to reset those ions in the soil for proper ion exchange. Pretty much next time you water water with more runoff height high ppm. I think you just need to feed your plant more. You can try to EC stack for the next three days.

Issue: weak and pale looking new growth. Mag def looking old growth. Cupping under on some growth scattered all over. Some low some high. Thought cupping maybe wind burn but adjusted wind and still happening. So I have noticed signs of mag deficiency which is strange to me, as my runoff ph is sitting around 6.5. Which is a bit higher than my last grow. I'm attaching pics.
I adjust my water ph to 6.2-6.3 religiously. I usually only flush my plants if they ask me to.
I'm growing 2x blue dream photos In 5 gal fabric pots. Week 7 of veg was gonna flip at 8. But not if I can't fix my problem.
Light: 2x 300w mars hydro lights (1 e3000 1 tsl2000 side by side for bigger footprint) about 23" above canopy.
Soil: roots organics original
Nutes: gh flora trio and cal mag
Dechlorinated tap water.
I have both pots elevated. Where air can get all around.
Temps at around 75 at night, 79 to 80 during the day. Humidity stays at 50%. Lemme know if you need any other info.

What percent is your light at?

What is a good ppm to water at in veg? I check my ppm it was around 700 this feed.

I got them both running about 500-550 ppfd. At about 55%

Is different for every cultivar. But looking back at your original post, I can see your problem. Your VPD is just way too high and those plants are water stressed. The plants are not able to properly take nutrients you need to your humidity. You wanna keep a VPD of .9 to 1.2 in late veg. I will keep your temperatures the same but up your humidity to match the corresponding VPD

The plants are not able to properly take nutrients you need to your humidity. You wanna keep a VPD of .9 to 1.2 and late veg. I will keep your temperature is the same but up your humidity to match the corresponding VPD

During the day you have a VPDof 1.75! That is simply just way too high! After around 1.6 the stomata start to close due to rapid water loss. You need up your humidity to at least 65% and you should start seeing improvements.
Late veg/ early flower VPD (.9-1.2)
Mid flower (1.2 - 1.4: I would keep it around 1.2 through most of flower, but just try to stay within the range)
Late flower (1.4-1.6)

Summary: so pretty much your plants are completely water stressed and because of of this, the plant has to slow down water uptake to prevent excessive water loss. Thus you have a nutrient deficiency.

What do you use? If you don't mind me asking. I'm looking to expand past what I started with. I only use flora series because it's readily available to me in a town where I have like nothing but a Walmart

Hmm there is a good spot buildasoil.com that has learning resources AND good products. He also has a youtube channel. Gaia green is a lot easier, I highly reccomend looking into that and then hang around the farm so we can answer your questions

I absolutely will! I love this place

I'm watering til about 20% runoff. Comes out to about little more than half a gal. Sometimes maybe ¾. I water usually every 72 hours. Going by my lift test.

The speedbumps and pronounced venules look like over-watering to me. Your watering volume is lower than I'd expect to create 20% runoff, and your watering frequency is higher than I'd like in soil. You might try slowing down the process of your watering to see if you can get more into the pots. That might let you give them a longer dryback. In 5 gals of soil, I'd expect to be able to get between 1.25 and 1.5 gals of water in before reaching saturation. I haven't run your media, so this is just something to consider.
