Plants will droop naturally through the grow. They don’t look light stressed at all from what I can see.
Just make sure you’re giving them a good wet/dry cycle so they get enough oxygen. And they’re probably getting close to needing more nutes. Happy frog will carry the plants into about week 4ish but then you gotta feed them.
They look like they’re entering flower??? So they’re gonna want a lot more P and K here. Pump those lights and feed them and you’re set buddy. Looks good.

Sounds good. I am in the wet/dry cycle. I did give them 1 gram MC to 1 gallon of water about 7 days ago. the last watering about 3 days ago was just ph water. I am watering tomorrow, so I will add MC this time.

Not to windy on plants though?

No signs of light stress, I would recommend a good drench on those ladies. I’m a Mega Crop user as well, are you using the 1 part or 2? Make sure you follow a drench to drought routine with liberal run off when using synthetic fertilizer Grow Bro, check your run off numbers on the drench days to monitor the mediums PPMs and PH

Overall plants look good, a watering or feed, the soil looks a little dry. Plants being auto’s, if you’re going to top that should happen pretty Soon. good luck

Whats your soil PH? Test any runoff PH. How close are your lights? How many watts is each light? How heavy are you feeding them? Are they getting enough air/Co2? I like to use the mushroom bags for Co2. Sometimes a fan on too high, directly on them will stress em. Same w the lights. I set my lights at 18” and I use a 1100w MH/HPS w a dimmer. So as they grow, I turn it up from 600w to 800w then full blast when it starts to flower. Airflow is key. I exhaust my tent outside, have a beast AC for the room to cool the light, equipment and intake for the tent. I use 2 small fans in a 5x5 to keep it circulating. One fan up high on low, and one on the bottom on low. So the air swirls. I also leave a top vent open on the tent so heat can escape.

Gave them all a good watering with Mega Crop nutes. Looking good so far. Put my light from 75% to 100%.
Thank you to everyone that helped out!

The brown spots in the leaves in the first picture are from a nutrient deficiency (usually calcium or magnesium if you use soft water).

@randylilgnome Tx man! I do use soft water. I was going easy on the nutes since last time I did autos I had used too much. Then again, I was using Ocean Forest and added too much nutes on to of it. Tx for taking a look at those leaves. I was wondering what the discoloration was from. This will be my fourth grow, second with autos, so all the help I can get
Cannabis plants are greedy feeders and can take a lot more nutrients than most plants, so it’s pretty hard to overfeed them. If you ever spots or faded leaves, it’s usually a nutrient deficiency and adding a liquid fertilizer a little more often usually helps.
If you use reverse osmosis or rain water water, or have soft tap water, then you need to add calcium and magnesium to compensate for the low mineral content in the water.

On the shorter side. Runoff has been good. PH between 5.9-6. PPM between 900-1050. Think I stunted them a bit early on. Seems like I will get some decent buds. Nothing against autoflowers, but I think I am more geared to the photos. I definitely need more recovery time during vegetative stage.
