Newbie advice urgently needed!!!!!!!!!!

[dubstepbandicoot]

so my random bagseed is 28 days into flowering and a few of the leaves have started turning gammy. started with the bottom leaves turning yellow and crispy. now there are dark patches on other leaves further up the plant.i am using a 250 watt hps bulb and its planted in a coco/soil mix. nutrient wise im using biobizz biogrow (NPK: 4 - 3 - 6) 1ml to every litre of water, biobizz biobloom (NPK 2 - 7 - 4) 2ml to every liter of water and biobizz topmax (NPK 0.1 - 0.01 - 0.1) 1ml to every litre of water. feeding every 3 waters. any ideas whats up?? cheers in advance guys. heres some pics . . .

What is your PH???

 

[RIKNSTEIN]

Looks like you have a toxicity going on, (nute lock out) "I would" flush with 1/4 strength nutes and transplant into a 5gal pot...flush is 3x the water as pot size....1gal pot=3gal flush w/mild nutes, and I would stick to 1-1-1 nute solution..I'm 4 weeks into flower and I'm using a 10-14-14 at almost double strength, and when you water her let some runoff come out, that way you push out the old and let the new do it's job...good luck

Ph/nute lockout/saltbuild up. Flush an fix ur ph ide say n give very light nutes next watering

 

[xGrimace]

Seems everytime i read about coco soil mix plants look like this. Coincidence? Or just leave it to the pros.
Looks like a combination of things, and trying to figure it out will only confuse you more, best to just flush it with some ph balances water with VERY mild nutes.

Yep, that and hydro.

 

[fattiemcnuggins]

What soil the coco mixed with? Maybe some underwatering going on as well? Just looks a little limp

cheers for getting back so quick guys!!

Budsworth - i think my ph is around 7. i cant really get an accurate reading as im using litmus paper and cant afford a proper ph meter. thats slightly high isnt it?? any way of dropping it a touch with household goods??

RIKNSTEIN/Noob grower 1 - okay so im gonna go get a bigger plant pot n transplant it . . . hopefully i haven't done to much damage!

fattiemcnuggins - i think its just ordinary soil man brought it from my local garden centre.

all of the leaves that are looking bad should i just leave them on the plant or should i pull em off? some are looking like they're about to fall anyway

If you are going to use a soiless mix, you need a PH meter. Your nutrients should be PH'd to ~6.2. This is pretty important and if it is too high you will lock out your Phosphorus and your bud development will be reduced. You can see this in pic 10 with the dark blotch.

iv transplanted it this mornin n flushed it alot! is the damage reversible?? will it get better or are the leaves fucked now??

Sorry no, the leaves will not heal, and no don't pull them, they still have a purpose, to hold water and nutrients for the plant. Just let her be for a couple days, you will not notice any improvement for at least 3-4 days, look to the new growth for healthy leaves and when you nute agian start small and work up to full...good luck buddy

 

[dubstepbandicoot]

thats a shame . . . okay il leave the leaves on cheers man

 

[Sand4x105]

Those leaves are yes: "fucked now"

They are dying... and almost dead...a dead leaf does no good for plant...

You can pull them, or take trimmers and trim the old burnt bad leaf off....

Take care, and good luck....

 

[RIKNSTEIN]

Yep if it's dead it's dead and no help to the plant, but if it still has green on it, IMO, I'd leaf it..lol..

looks like simple Nitrogen deficiency to me.
You should be feeding it a "Veg" food for the first 2-3 weeks of flower. Hit it with a higher N food now to stop the spread of yellow.

[dubstepbandicoot]

Sand4x105/RIKNSTEIN - okay so im thinkin the leaves that are dry and crusty trim off and the ones that are showin slight signs of life leave on

Dr Gruber - interesting read man defo sounds like what i've done . . . when it dries from the flush im gonna feed it minimum nutes then in a few weeks keep it on a watered down amount of my bloom ferts

thanks for the advice people!

 

[dubstepbandicoot]

whoah there homie.

first, your probably overwatering, coco holsdfs TONS of water and nutes and turn in to a swamp while still looking dry on top.

your plant is stretchy and thin, so it needs LOTS more light, i mean LOTS, and if you pull her out of the pot i bet everything under 3-4 inches down is soggy slimey and messy as a motherfucker.

if so,
put that plant in a MUCH BIGGER pot with fresh dry coco and soil mix all around youre current rootball, then dont water or nothin until the whole pot seems light.

when you DO water, watch how much the coco soaks up. youll be amazed at how much that shit holds and how long it takes for your scrawny underweight reedy plkant to use the water provided.

TLDR; your overwatering and need lots more light.

With 30 days left in your flower cycle are you sure your plants aren't simply beginning to use up nutes from their bottom leaves? I've got leaves that look 10x worse on extremely happy flowering girls (within their last 2-3 weeks). So... Yea? No? Doesn't look like a huge problem to me.
