leaf problem AN nutrients

Strain.....London lemon
Medium... dwc
Water temp....16degs
No root issues

Temps... 25 degs light on.....17 degs light off constant....

Lights....A/C reflector...600w 400v digital lumatek pro ballast and 600w 400v bulb

Air flow great ....

Ph set at 5.8 raises to 6.3 after 1 day reset to 5.8

Ec dropping every day (plants eating)

Water consumed every day...

Period....7 days into 12/12

Nutes used..... AN rhino skin..AN sensi bloom A+B....AN bud blood...turpinator....canna boost....elixir steriods....algamic (kelp booster).....

I am not using ro water currently and the water I am using has a starting ph of 8 and a starting ec of 0.8!!!!

This is only effecting this strain.....

I am tinkering with feeds and using additions like bud blood very very minimally.....as I wish to go back to using just npk as research has told me it's better however I am scared to run just npk right now so am monitoring end product as I wind down The feeds..

Please all suggestions welcome....

I feel it's either

...random government added shit to water....

Poss over fed (the lower nute ratios in my buckets are causing faster nute uptake?)


Poss calcium diff....

I have another in late flower (this one's mum) doing the same....poss infection or disease. ...

Please help skillfull minds

The one above mother. ...later in flower....leafs started same as above turn yellow crisp up curl up and die...

Please take a picture from the whole plant.

The color of those spots is telling me that your tap water may have a high sodium content. Not sure though.

I will take some later when I'm there see you in a few hours

This is the mum.....week 5 flower bud development is slow then norm but buds are filling out..


This one's how it started off......




And this one cause she's purddeyy even tho she's a ruff looking slapper.... lol

here's your problem:
"Nutes used..... AN rhino skin..AN sensi bloom A+B....AN bud blood...turpinator....canna boost....elixir steriods....algamic (kelp booster)....."

Over Fert.

Looks fine, continue doing what you are doing , remove yellow and dead leaves.

The only products with npk are bud blood and sensi bloom....the rest are boosters / growth enhancers....and only added in tiny amounts.....

Thanks though....

Thank you man but there is defo a problem here .....

I already told you, 7.5 is a way-too-high pH. 5.8-6.8 in soil, 5.2-5.8 in hydro.

Unless this is a different crop.

Water should not be used every day either.

It's not a different crop. You're overwatering, and your pH you said originally was 7.5 in the last thread, and hence the red veins/phosphorus deficiency, along with the other deficiencies.

Olivedrab, where are you seeing the pH is 7.5?
Lemon, you have dark green leaves with leaf tip death and you are putting quite a lot of stuff in them (even if it is small amounts). Over fert, I'm telling you. Give a plain water flush and let them finish without more ferts. That's what I would do.

It was in his original thread he posted earlier with the same plants.

Olive fuck knows wot planet you are on I grow dwc.....over watering. ... I hope not.....

Hmmmmmmm.....the only thing making me say nay is that I have ran this strain..... nay... cut at least 15times and never had this happen......

I have put them on a basic low ec npk feed....we shall see...


I hate having a prob and not knowing what it is causing it....how will I fix it if theres a next time...



Still growing....

You had said in the last post that you had a pH at 7.5. That's still too high, isn't it? I don't know shit about Deep Water Culture, but I though hydro was 5.2-5.8.

Olive no offence but if you was to read the very first post fully and properly you will see whats going on....thank you for taking the time to read it....

Which brings me to point number 2.....please stop offering advice if your not going to read the op.....

Sum sillya then me could take your advise and you could make things much much worse or potentially kill sum1s babies...

Not cool dude.....

Not cool

Did the problem start in lower older growth or upper newer growth when you first noticed it?
