NEW GROWER, PLEASE HELP!!

[darwinsbulldog]

hey all, i'm having issues with nute burn at the moment. i'll add photos below to show you what's up. anyway obviously i've given these plants too much nutes and have flushed them both extensively with about 3x as much water as there is soil per pot. is that all i need to do and just give it water for a week then 1/4 dosage of THC A and B Fertiliser?

also to note i water them with water/white vinegar solution to drop the ph to between 5.5-6.5ish as it's normally at around 7. (currently at about 6 for each plant).

they're under cfl lights at the moment (2 x warm white, 2 x cool white) approx 4"+ above the plants, and the temps about 25C-28C. there's plenty of ventilation too with a fan on 24/7.

soil for the power plant on the left is mainly coconut husk (hence adding the nutes, those this plant doesn't seem to have any huge issues) and the other one is organic mixture with blood and bone and some pot ash in there too. also there were white crystals forming on the soil surface of this pot (my mate used a sprayer for the nutes and yeah i think it's been way too strong). anyway if you need more info in order to help me please just ask. thanks heaps for your time guys!


oh ps. while i'm here i might as well ask. i took clones from these today (1 top cut off and 2 low stem cut offs) i've got them in some chinese food containers to try and keep humidity up, and have sprayed them a number of times with fresh water. i used gel, cut the bottom of the stem in half (from jorge cevantes book) and placed them in rook wool. is this going to be ok? or do i need to change any methods here. thanks again.

View attachment 52255 - this power plant looks ok, just has a few of these white markings on a few leaves.

View attachment 52253 - these are the clones (has another chinese food container over top too)

View attachment 52256 - this is the not so healthy nute burnt (i believe) white widow.

View attachment 52254 - white widow on the right, power plant on the left.

DBD a warm welcome to you...sorry to hear of your problems. Those don't look to bad...what I mean is I think you have it under control and given a little time they will recover nicely...we hope. Do you have a way to check your PH? DD

darwinsbulldog, welcome to icmag!
You're plants don't look too bad so don't fret.
I'm gonna move this thread to the infirmary, more help will be found their. Also. look thru the stickies in the infirmary, 'stitch has great picks that you can compare your plant to.
One thing, in cloning you generally take side shoots, not the actual plant top. Though, I'm betting the top will root as well...
your clones look good so far.

hey doobie, yeah i have a soil ph tester at the moment and soil's normall around 6.8 when i test it before watering each day with a little water/white vinegar, then it drops to around 6 give or take. i'm getting a water ph tester too soon so hopefully it'll help me out with having the water at the right ph all the time. have you any suggestions at how high or low the ph of watering water should be etc and the best ways to control it? cheers again guys!

evlme2 thanks heaps for that. i was looking for the sick plant forum but couldn't find it so thanks for moving it there. umm yeah well with the cloning 2 of them are side shoots and i heard they're the best hormone wise compared with the top which is the worst place to get them from but being new to it i just wanted to try with all the trimmings we took today as we were going to top the plants anyway. just for the added experience so if we get it to root or not either way we'll be learning something. cheers again guys!

you should keep the pH of the one in coco at 5.8 - 6.2

I'd keep soil at 6.2 - 6.5

High pH can cause excessive Calcium to present and it will precipitate with Phosphorous and tie it up. You are showing P def signs with those necrotic patches. You need to get some pH down. The alkalinity in your water will buffer it back up in a short time using vinegar.

thanks for that mate, i went out this morning and got some sulphate ion stuff that is a soil acidifier and watered a little bit in until it ph was around 6.1-6.2 i hope this fixes it. here're some photos from this morning of how sick she looks.

i hope she's not wilting because i'm watering too much, there's plenty of space at the bottom for excess water to drain out.

Darwinsbulldog,

I'd have to agree with your previous help and add that old leaves are "old news". They probably won't recover. But your new growth is looking good and that "new news" looks good for the future health of your plant.

Good luck and stay safe, mate.

Hi Dawin', I have to disagree with the PH for your soil, I would be trying for 6.8 to 7.0, you may have good results as low as 6.5 but no lower!
Your coco is good at 6.0 but the vinegar needs to go, it is too unstable and leaves goodness knows what? in your medium.
With PH down you will not need to adjust quite so often, your plants will thank you for it.

 

[statusxqs]

Yes im grow on cocos ph6.0.

Grtz

hey wanderer, yeah hopefully it all sorts out i'm not too fussed about the leaves as long as the new growth and future health of the plant is ok. the ph is currently at about 6.5-6.7 and the coco one is about 6.2. i think i've overwatered the white widow as it's now droopy as, but i'll leave it for tomorrow with this adjusted ph and hopefully it picks up a little. the power plant though is still going nuts and looks very healthy. thanks again everyone for your input. i'll upload some more photos tomorrow, tell me if you think it's improved or got worse. cheers again!

cheers for the reply hazy lady, i'll ditch the vinegar and yeah am using ion sulphate acidifier at the moment which is watered into the soil and drops the ph. if this doesn't work well in the coming week i'll go find some decent ph down. hopefully it's ok though

ok so i did a little more research into this issue with my plant and it's apparent issues. according to this vid it said nutrient deficiency can be a side affect of overwatering and i think due to my thinking it was nute burn and then flushing the plant, then trying to fiddle with ph and giving it more acidified water that i've over watered the crap out of it. this vid said to replant them if they've suffering from nute def because often at the bottom of the pot it's like mud and is holding too much water. (i thought all excess water would drain out, obviously i was wrong) anyway here's the link - http://www.youtube.com/watch?v=jJyZzL2sj8k

so i did what they said, mixed up new soil with vermiculite, organic potting soil and seedling mix and replanted it in there. low and behold as i pull the plant out the roots haven't taken and pretty much crumble away with the muddy dirt at the bottom, so i removed all the mud/water logged roots in that mud too and planted the root base in the new soil. hopefully i've done this in time and can save this plant as she looked amazing only a few days ago! : ( i also put a few slow release nute pellets in (a pinch) and gave it only a few squirts of acidified water on the surface with those pellets. hopefully i haven't made things worse here... if i have, at least i'll learn from it all i guess haha

here's are some pics... the power plant on the right looks tits so i must be doing something right with that one at least.
