Yellow leaves in flower

Hey,

I’ve got 3 blue dream plants in flower right now that have started to turn yellow. I believe it to be a nitrogen deficiency but maybe I’m wrong since I have not been able to remedy it…Am I correct, or totally wrong and need to try something else? The front left one looks fine and seems to be chillin, the front right one is the worst of them all, the back one seems to be suffering a little but not nearly as bad. I have a fan close to the worst one to move air through the plants, could that be the problem? (maybe it’s drying to fast or something.)

Grow environment:
Fox farm nutes dirty dozen+calmag from botnicare
75 degrees/45-50% humidity
4x4 tent
3 blue dream plants, 2 in front 1 in back
roots organic soil
always PH everything to 6.5
calmag every water, plants had some problems before i started doing this

Probably forgot some things, lmk if any other info is needed. Here are the pictures:

Beautiful BDs! I’m assuming you’re in soil with the 6.5 PH mentioned? Do you have run off PH and PPMs :love_you_gesture:

Thank you :slight_smile: Yes I’m in soil with 6.5. The runoff is around 6.3-6.5 depending on plant. My PPM meter stopped working last grow, and have not bought a new one :sweat_smile: I will order one and see.

I’m thinking about flushing with sledge and seeing if that helps, but was hoping someone might know what was going on before I do that

Bump? Help would be appreciated, I don’t want it to progress to a point of no return :sweat_smile:

How far into flower are you?

The way they’re losing color I want to say magnesium

They are about 4 weeks into flower

I can give it a shot. I currently give them a tsp of cal-mag every time they get watered and/or with nutrients. Do you think 2 tsp would help then?

Maybe try bumping up the big bloom.
I am giving two shots [shot glass] big bloom 3/4 to 1 shot tiger bloom and a 1/4 shot grow big to 4 or 4 and a half gallons water 6.8 ph
Don’t know your mix hope this helps
Also every once in a while some micros
And cal mag every other time just a cap full from a pint bottle.

I would try epsom salt once a week

I will try giving a bit more big bloom. I generally just use the soil feeding schedule they have on their website but obviously that’s not working

Do I need to do any research on kinds of epson salt or can I just pick up any bag of it at home depot in the garden section and be good to go. I’m unfamiliar with it

That should work

It would really help to know what you are feeding how much of what to how much water is in the mix before you noticed the problem and what you changed it to after problem came.

What is your ph after adding nutes? I made a stupid mistake as far as not checking ph after adding nutes and it yellowed my leaves and slowed growth tremendously. Ive got her back on track now, but shes getting there… my average ph was 5.4…

That looks like a nitrogen deficiency

I’ll add magnesium to that @ChittyChittyBangin , what’s your run off PH now? That could be the issue with nutrient uptake :love_you_gesture:

@OGIncognito my start runoff was 5.4… i flushed and then got it raised up to 6.7 or so for nutrients… they havent progressed any worse and the flowers are fattening up

Perfect, keep an eye on the new growth and if you’re not adding epson Salt to your feeding routine it’s a great source for magnesium and sulfur. 1/2 teaspoon a gallon :love_you_gesture:
