Anybody know what deficiency I’m having. 7th week flowering.

[Hawse99]

Blue cookies strand. Haven’t teally changed much. Cal mag hydro guard and fox farm nutrients.

 

[Cwmoore577]

how often are you feeding and what strength?
They look tox to me.. clawed, dark green, tip burn

 

[WinterSoldier89]

Looks like you overfed on the nitrogen leading to a lockout, and now you have a potassium deficiency.

Start of week 5, Phosphorous needs go up. If your not Locked Up, you can increases your Bloom food.

They are almost done and over-fed. I wouldn't feed them anything anymore and ride it out.

 

[Hawse99]

I feed them below the recommended amount. But I can say I don’t water with just ph water. I’ll try and ride it out like he said and just ph my water. It has really took over my plant now. They also look pretty small. This is my second grow. I thought it was cal/mag problem cuz I use ro water.

Overfeeding can lock calmag and other nutrients out. I’d give them just water for the next few watering.. if you have some that look like they’re taking a turn for the worse I’d consider flushing them.

Also the “normal recommended dose” for nutrients is always way too much. Usually go 1/2 to 1/4 depending on the strains need and even then I’d stay on a feed-feed-water schedule. Wouldn’t feed every time unless in coco/hydro

Update pic from last night. It is a hydro grow. I will water tonite and see how that goes...

Next grow if you stay with hydro I would switch to something like General Hydroponics 3 part Grow, bloom and micro.

Overfed.

To use a decent EC metre really solves problems like this in hydro. Try a good branded one.

And I have one. Got lazy and stop using it.

 

[WinterSoldier89]

I use RO water, i replace what i took out using cal/mag, GA extra traces.

I like your name pick. Especially if you only grow in the winter Bucky.

This was a random name xbox generated for me, i'm glad you like.

i second that, thats very good advice, cal/mag supplement at start of flower next time and remember nutrients are salts and dehydrate plants and can lock out cal/magnesium fast.
If in doubt run with water if hydro lower EC/CF . the most common deficiency is calcium and magnesium starts showing early/ mid flower

Bull Shirt... Most people except in coco reduce calcium in flower... One more time, Phosphorus issue.
