Third grow, second time with same problem (pics included)

If you have noticed that it's with the same strain, the same additive and you get the same results, you gotta change something up. Try dropping your ph down to 6.3, don't britta filter your water (that just takes out somethings you want to keep in the water). Ask your friends mom's boyfriend (or relay the question to him) and ask him if he has any tips. Are the plants nitrogen whores? Do they like really acidic soil? Are they temperature sensative? He should be able to give you some clues as to what that strain likes if he's grown it out a few times.

I had the same or close to it problem on my last grow. I started them from seed Last time and did SweetTooth this time I'm doing Cinderella99, 2 different strains and grow rooms same problem. I just started using the Britta filter, should i really not filter my water and use tap water?

My friend and his mom are not talking at the moment but he is growing the same Cinderella strain and I've seen no yellowing. he runs different nutes and a bigger wattage light, same soil and same pot size.
Another question do powder nutes have a shelf life? I've had these nutes for about a year and i have no idea how old they are even since i got them from a friend who moved away.
I have no problem changing my nute line if i need to but i would hate to waste the nutes i have at the moment.

looks like a Mg deficiency possibly S as well

So for a MG and or S i wanna use? CalMag?

Cal/Mg or N

epsom salt, most drug stores have it

you don't need any N just yet, your bottom leaves look green, if you get intervenial yellowing on the upper or middle leaves its often Sulfur, and sometimes mg.
mg can show itself a couple different ways.
just to be safe treat with CaMg and epsom, half strength each so you can address either deficiency.

I'll have to go some Epsom but I'll water with calmag in the morning to start with

let us know how it goes, may take a week before you see results,
It's 1 tsp or 1 tbsp per gallon for the epsom, I'm not entirely sure, If you look around you can find the right measurements.
