Can't correct my problem

Dont know strains or any of that . Random beans. 600 watt hps. 75 to 83 degrees f° and keep the room in 30 to 50 rh. Had a little fungus gnat problem that i eradicated with a 1 to 4 ratio mix of 3%peroxide and water. Took care of gnats and got the pics below 12 hours later

Thank you! And im growing in organic potting soil with peat moss. I use fox farms grow big and cal mag at the lowest reccomended ammount for my growth stage (36 days from seed) and i ph my water down to 5.5 after added nutrients. And i water every 3 or 4 days.

I don't use added nutrients, but I have seen many say that you should use 1/2 recommended dose. Not sure what exactly is in your organic soil, but between the nutrients and the soil you might be overfeeding them. Lastly, 5.5 seems low but I will leave that to others to clarify. I also water every 3-4 days

Fox farm nutes are pretty potent , iInever ran over half strength

Calmag at full strength

Keep yer pH 6.2-6.6, 6.3 is optimum if growing in soil

Good luck

Thank you both, il try cutting my grow big in half again and keep my calmag at the same level, do you guys think im overfeeding and thats why there dying off like that?

And also i meant 6.5 ph not 5.5.

Big bloom is not designed to be used on its own, it's part of a 3 bottle system with Grow big used now and tiger bloom in flower

I'd suggest getting grow big now as well
