Fast Buds - Indoor grow 3

n1mbu5 Ok guys 13.05 this is their second watering 200-250ml So 12.05 they were switched to 20 hours on 4 hours off (they were 24 on before). Light is on 75% using with the sunrise/sunset mode they are getting about 21 DLI. They seem to like it we will see how it goes. First watering since germination was 10.05, roughly 300-350 ml each as was getting the soil nicely damp, they are in larger pots and they didn't show any signs of over watering

n1mbu5 Ok they seem to be doing fantastic 💚 19.05 just a couple of hours after lights on watered plain water 400-500ml per plant 17.05 they had a little feed 300-400ml per plant Ok guys wish me luck and hopefully they will carry on like this🌱🤞 Ok just adding in here 21.05 watered with calmag and bionova auto flowering supermix, 350-400ml water each Light raised to 90cm, heat reduced to 27 hottest and relative humidity is at 50-60 I am going to put in my new Mars hydro humidifier today and I am going to look into getting something to better control the heat. I've added on some extra pics to show the leaf symptoms. Shout-out to everyone who answered my question I'm going with the calcium deficiency and heat stress suggestions for now and will adjust anything I have to then select the answer to my grow question. Hopefully it will be a small issue this time and we will be able to resolve it🤞

n1mbu5 Ok guys they seem to be better the signs of heat stress have gone. I have them a few light feeds with bionova and calmag and so far so good. They have just had some plain water 26.05 we are up to 600-700ml water per plant every 2-3 days Thanks to everyone who answered my grow question I am still observing the results so will give them a bit more time before I select the answer but so far it seems to have been a definite heat stress issue with maybe a calcium deficiency. Well that's it for now hope these girls keep growing we got some nice branching going on🌿
