Thanks! I appreciate that. We are looking in to the DIY lights now but wanted to get a decent set up as quick as possible. I do have Epsom salts. Due to the lights being a bit stronger should i wait to mist with it until the lights are about to be going out?I think it's low on magnesium, the veins are still greenish but in N def. it's really even yellowing all over the whole leaf surface, and having your more powerful LED on them will be making them extra hungry, especially for mag. Just up their feed a bit I guess unless you have a bag of epsom salts lying around? If you have, or you get one, make a foliar spray. Probably around a tsp/gal, and spray the leaves with that like every 2nd or third time you do your misting, and add maybe a tsp/gal with your nutes until you see nice healthy leaves again.
Nice set up, good job.
I think it's fine to foliar spray in the light but you just have to try not to go too heavy so water gathers right inside the growth tips because that's where the big droplets can form and is also where the most vulnerable tissue on the whole plant is, so I think that's where the thing about "water droplets forming and burning leaves" comes from. I could be wrong though so try at your own risk.Thanks! I appreciate that. We are looking in to the DIY lights now but wanted to get a decent set up as quick as possible. I do have Epsom salts.

Now is the time to test it out so I'll let you know. I've got them on a 12-12 now by the way. Hopefully i can get some help figuring out whether or not they are females.I think it's fine to foliar spray in the light but you just have to try not to go too heavy so water gathers right inside the growth tips because that's where the big droplets can form and is also where the most vulnerable tissue on the whole plant is, so I think that's where the thing about "water droplets forming and burning leaves" comes from.

It is and I do. I'm trying everything to get the temps down. They went back up to 82 at the end of my cycle.Is that your intake at the top? Do you have a fan exhausting the air out of the tent?
Oh then that is good. I had read that between 72 and 76 was the sweet spot. I was getting worried but the plants seem fine for now. Should have my soil in and my pots in by Thursday so i will be re-potting then.LED-grown plants tend to need a higher temperature anyway, 82 is actually fine. 90 would probably even be okay. You can tell when they're getting too much heat or humidity stress by their serrations all curling upwards.
Where are you seeing this at? As I'm still inexperienced and have no idea what to look for. I do have an exhaust and an intake for my tent. My plants are on a wooden stand in my tent as well so they are not in the floor and when i water i do so in a drip tray and let them sit in it until it is finished dripping. Then I pull the tray out since i discovered it doesn't air dry well. Anything else I can do to prevent mildew?You got a powdery mildew problem maam. Most obvious reason would be lack of airflow and or standing water on your floor. Airflow and ventilation are just as important as lights and nutes. You need to get an exhaust fan and start moving air in and out. Good luck.
It is interesting you say the about magnesium and calcium as the majority of the threads I pulled up on it put the 2 together. I'm using the FF trio so i will have to check the levels on the bottles when I get home. I imagine I need to swap to the tiger bloom as I forced these into flower to determine sex. Maybe that will have the magnesium.I think what Southside's seeing is your slight interveinal chlorosis from the mag. deficiency. Also when you added epsom salts, you were only adding magnesium and sulphur, no calcium, so you may still be low on cal. if your feed doesn't have enough. It's common for new growers to conflate calcium and magnesium into one thing, because it's commonly sold in the same bottle as "calmag", but calcium and magnesium deficiencies are two different things, and though you can have both at the same time, it looks to me like you only have a mag. deficiency right now, so it is incorrect to call it a calmag def. Sorry I don't mean to sound patronising I just think it's important to know these things.
It may be wise to invest in a bottle of cal/mag supplement when you can in case you start to see some rust coloured spots on your leaves, which will likely indicate a calcium deficiency, then use that instead of the epsom salts. I think you can make a DIY organic calcium supplement with crushed eggshells and vinegar, but I can't quite remember the technique. You may want to search for it on the "Rusted Garden" youtube channel.

You are an incredibly well-mannered person. Even in the South I'm not called ma'am that often. Not picking, just observing that politeness is rare now-a-days. And at that time I was misting my plants so they had a light haze to them in all the pictures. I didn't have a tent and my humidity level was low. Thank you for the observation.
