Need Help Identifying Deficiency

[huma]

week 6 of flower and my plants have turned lime green / bright green since week 4. I'm not sure if this is a potassium deficiency or something else. I'm using 18ml botanicare pro bloom, 5 ml cal-mag plus, 15ml hi-brix molasses. Please help!

Looks ripe to me, Id say you shoulda stopped feeding them by now, especially the molasses. Flush them as long as you can and chop chop

Looks to be pretty bad nitrogen dificiency... the way you can tell is how consistently pale the leaves are as the dificiency moves up the plant. With the most effected leaves being at the base. Week six and they're supposed to be done I'm assuming 8?

 

[Lbgrower]

What medium are you in and do you PH your water if so what to. Also what's your feeding frequency. These things matter I would need some more info.

I'd agree with lbgrower do you keep
Feeding veg Bute's for first couple weeks of flower?

 

[Funk junky]

Veg nutes

 

[Funk junky]

What medium are you growing in too

 

[huma]

Pro-mix soil. I fed pro blend grow veg nutes for the first 2 weeks of flower. I started ph'ing the water down to 5.5 a little over a week ago with no change in the plants. Tap water is neutral at 7 so I haven't brought the ph down prior to last week

 

[Lbgrower]

That's too low for ph

 

[huma]

Feeding nutes is once per week. Mid week, I feed once with just water.

 

[Lbgrower]

There's your problem you should have a ph probably 6.5 and for sure no lower than 6

 

[huma]

I'll try upper the ph a little and see if that helps.

 

[Lbgrower]

Once a week is good for feeding the issue you're having here is lockout from that ph being too low. Mix your nutrients and correct that PH give them a moderate watering to make sure you know out that stuff that's in the pro mix. I would say give 30 percent run off with your new solution. Then just make sure to keep the ph higher till the end.

 

[Lbgrower]

Switching that soil ph too quick is gonna really shock the plant. From here on out if I were you would keep the ph between 6 and 6.5 when the mixture is going in. Make sure it's somewhere in that range when you apply nutrients.

 

[Lbgrower]

If your tap water is at seven it should be good for flushing with. But you don't look like your there yet so hopefully those leaves will green up for you after this PH issue is cleared up. :)

I had one that looked like that and it was a root problem check it out when you cut it down

 

[Lbgrower]

Must remember as well that yellowing is a normal part of the plant finish. So this may have been a hiccup for you in this grow. May not recover or maybe you just continue flushing. That's all up to you. What I do know is week six they shouldn't be that yellow I also believe it happened pre maturely because that ph was too Low...

I had one that looked like that and it was a root problem check it out when you cut it down

I'm not seeing the totally dead leaves that would appear more like ROOT ROT..

 

[Lbgrower]

looks like macros are locked out ...makes sense

 

[DrMcSkunkins]

Looks too late into flower to do anything about it, giving it nitrogen and such will just cause more problems, Id flush for a week and chop it.
