Hey guys just wondering but i think i have a calcium deficiency and i dosed up on epsom salt to correct but it hasnt helped much and the yellowing in the leaves are still happening so could this be a nitrogen deffeciency, even though ive been using 2.5 teaspoon grow big and 2 tablespoon big bloom? Or should i just switxh to cal mag? If switching to cal mag is best the bottle says 3-5 ml per gallon but should i start off with less? Also, i had an issue with mildew so i picked up some garden safe fungicide and mixed 3 teaspoons in a gallon of water and put it in a sprayer but my question is, ive been running my lights 24 hours and ive read that you only want to spray when the lights are off, so would it stress the plants to turn the lights to 18 on 6 off for today and then put them back to 24 hours on for the last two weeks of veg? And my humidity temps are now at 50 percent, they were at 70-75 when i got mildew
Thanks!

epsom salt changes the PH of the water so did you check the PH before you watered?

you are loving your plants to death, To young for all those nutes, your soil should be enough for 3-4 weeks. WHY are you using cal-mag and epsom salts? epsom is Mag. not calcium for one. You probably aren't checking the ph of anything and probably are using ocean forest. SO, all kinds of issues here. TRY, just giving her some nice ph'ed water a few times and see what happens. LESS IS MORE.

I would say the epsom salt droped the PH way too low so when you watered it the plant couldn't uptake the nutes. whan you get your kit do a test with the same amount of epsom salt and water and see what you get.

Shoot for a bit lower, somewhere in the 6-6.5 range. The leaves pointing up like that is a good thing. It's called praying. They must like the new light. Don't over feed and they will do just fine.

Hey guys so i got the test kit today and my ph is neutral 7.0, nitrogen low 6.0, phosphorus low 6.0, and my potash or potasium didnt turn brown when mixing? Also just wondering but i read thay ph up and down will not work in a soil grow? If thay is the case is there home remedies like baking soda and distilled white vinegar that is safe that i.can use? Or should i just buy dormilite lime for ph up right? Then what for down?
