Is this the first sign of overfeeding or something else, whitewidow x northern light cross (crystal nirvana seeds)

2ml bio grow
1ml bio bloom
just entered the 3rd week of 12/12

Only on 2 plants out of 5 but want to nip it in the bud.

only a guess, but, is it only on the leaves closest to the b/w? is it possible its a hotspot? The plant look in good health mate, The first sign of overfeeding is the leaf tips start to burn first
E2a i've just noticed the tips in the bottom right of the second photo, that could be due to nute burn

What nutes are you using mate?

[DrWho]

Nutes are bio bizz,

sorry whats b/w??

tips in the second photo are of another plant (same strain) thats 10 week into flower that showed the same signs as the plant above only much worse, leaves never recovered even after over a week of just plain water feed. pic attached

, all i can give is my opinion mate, sorry!

I could be wrong, it just looks to me as if those plants need some more nutrients.

Its all trial and error!

[DrWho]

not your fault mate, i'm just looking for some clarity.

If it over feeding what are they getting too much of: N, P or K

same question if its under, then i can adjust the ratio of grow to bloom rather then increase total nutes.

[Floyd]

If you want a definitive answer mate, I would list everything about your grow, feed, environment, where the def stated and how it spreads.

[Stonehenge]

Too much grow mate. N toxicity can cause the 'ramshorn' type curl.

With Biobizz I used to be feeding around 1ml grow and 2ml bloom at the stage you're at.
With the one at ten weeks what dose did you feed that one?

The one at three weeks doesn't look too bad though dude..

Good luck!

[DrWho]

grow is in a tent in an uninsulated attic
250w light
bio bizz soil and nutes
temp ranges 18-24 at the top of the pots and at the side just below canopy level
under the lights at canopy it gets to about 34.

The lights off temp is maintained by a thermostat controlled heater fan sat at the bottom of the tent pointing upwards

On the younger plant it has only just started, the last feed was
2ml grow
1ml bloom

The feed schedule i'm following states to feed only bloom from next week at 3-5 ml.

If theres anything i've missed just let me know.

[yosser hughes]

to much N flush then feed an alrounder. they r sick.

[DrWho]

Thank you Stonehenge and yosser, only just seen your posts. I will drop the dose of bio grow to 1 ml this week then cut it out all together from next.

The older one had a lot of issues, was feeding 1.5 ml grow + 1.5 ml bloom but then i was advised they looked under fed so i bumped it up and that's when it started to curl, didn't notice it as quickly though. Also i think it revegged after starting to flower which is why its still not ready, at least 2 more weeks i think.

[sensiblue]

They don't look that bad mate, why don't you cut out the grow now and just try them on bloom.
