okay~!
Third grow, this is the second time with this same or close problem.

Information on the plant:
28 days of flower temps are 75-85 and humidity is 40-50%
Clones from my friend who got them from his moms boyfriend. The strain is Cinderella(99?) from what I'm told.
These 3 clones are in Grow Pro #3 pots (3gal?) with FoxFarm Ocean forest soil. I did 2-3 weeks under a two foot duel bulb T5 6500k.
After about 3 weeks I put the clones under a 400 watt MH and after one week switched to 400 watt Hps

Soil Ph tests out at 6.6 and for veg nutes I used a spray mix of Verde (Npk of 16-1-2) once a week with Britta filtered water, I use just the filtered water every watering after it got any nutes.
During flower after about a week and a half of regular water i started with Open Sesame the FoxFarm chart says 1/4-1/2 tsp once a week
I myself started with .74tsp (1.2ml) and after about two weeks they were still looking good so i move to 1/4tsp and WHAM right before I'm about to start using Beastie Bloomz this happens.
I just added 3 Blueberries to my flower room and have yet to give it any nutes, any help to avoid this for a third time would help alot.

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.

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.

Watered with Calmag and Silica Blast along with my normal feed (Beastie Bloomz). I also went out and got the Epsom, I'll go add it to my next watering in a few days so i don't over water.

Simple - ur using a veg fert (high in N and low in P & K) for flowering which is why it looks P & K def. change fert right now and keep PH to 6.5

I'm not using a veg nute, i stated that during veg i used a high N spray and after a few days of 12/12 moved on to Open Sesame (the first of a 3 part Flower system) and since have moved on to Beastie Bloomz.

And forget the Epsom salt, the flower fert will have higher levels of Mg.

This Def didn't show up until i started using my flower nutes. it has done this 2 grow in a row.

The thing is, if you add Mg and not Ca in equal parts then one will cancel out the other.

As for the fert, you should be using veg nute on 12:12 for about 3 weeks, until buds start forming. Above you have written that you changed fert after a few days on 12:12 ??

Maybe change fert. I'm planning on switchi9ng back to Hessi but I've been using Canna.

thanks. I dosed em with Calmag yesterday and I have Epsom salt now if I need it.

Epsom salts is not the most water soluble, especially with room temp water. Take a quart jar of water and warm it in the microwave. Then mix 2 tablespoons of Epsoms salts in it and mix well until its dissolved. This is now your magnesium concentrate plus a bit of a sulphur boost plants love during flower. You can use this concentrate as an additive to your feeding program. Usually 1/4 to 1/2 teaspoon per gallon of water is all it takes...this is old school and has been used by gardeners for decades....
