Newbie in need of help.

stonerpaddy · Jun 26, 2012

Hi all, hoping for some help with my grow. Im 4 weeks into flower with Toxic Blue and all went well so far but now all of them are are showing yellowing from the bottom up on the fan leaves. I have read through the forms and am fairly certain its nute burn. The tips of the leaves are showing signs of burn but on some of the threads yellowing of leaves is said to be a Mg deficiency. I am using 5 gallon pots with Biobizz nutes 600w Hps at about 18" from the tops. I know people are probably sick of answering the same questions but any help is appreciated.

if its just the bottom then there most likely not getting enough light down there

Looks like nute lockout.Most likely due to an acidic substrate.flush with some 8.0 water to pull the 6.0 or lower grow medium up into the 6.4-6.8 range.Basically flush with slightly alkaline water until the runoff is 6.8 or so.

Either way a flush cures over feeding and puts you back at square one.Add weak nutes a few days after the flush.Weak is better than strong.you can always go a little stronger on the next feeding.Allow the plant to tell you what it needs.

It started at the bottom and I did think it was just old leaves dying off but now its moving up along the plants jman23.
maulcoy, I'll give them a flush so. At this stage its better to do something rather than nothing and thanks to both of you for the replies

@sick of answering the same questions

rolf

yea I guess they are .. Im sure as sick as I am reading "plant problems" threads and leave problem guides .. googleing for answers aso.

seems like evry problem could be cursed by .... well evrything .... curl bud leaves and yellowing fan leaves at the bottom as I have (3th week in to flowering)

could be Bc. of to many nuts .. to few nuts .. to much N. ... or overwatering .. or to littel water .. or MG Def. or or or !!!!!

wish I could talk leavish so I could ask them leaves what exatly the problem is ...

stop feeding......stop watering.........dry out.........re-assess
imo

stonerpaddy · Jun 26, 2012

Slipon, I feel your pain. Sometimes the net has wayyy to many answers. Guess its going to be down to figureing it out as we go along!

stonerpaddy · Jun 26, 2012

scroglodyte, was thinkin about doing this after a flush as mentioned maulcoy. Figure check the pH runoff after the flush and adjust as needed. let them dry out and start with fewer nutes. This is the only road at the moment as far as I can see. Thanks for the ideas again lads

yea I also came to that conclusion .. and in then end it is also just up to one person ..

btw
I gave mine Epson salt (English salt/Magnesium sulphate)

12$ at the wellness store .. did wonders for my light greenish coulor I had at the top of my plants .. look realy helthy now .. tho did`t do much for my small bud leaves .. still curling .. tho now a more dark greenish ..

could maybe be a idea for you to try ? dont think it can hurt .. 1 tespoon per gallon (use a cup of boiling water to dissolve the Epsom slat before adding it to your water .. use a light feeding/nutriens as Epson salt also effect ECC .. or add it when you only use pure water ..

stonerpaddy · Jun 27, 2012

Have the Epsom salt got already. Flushed 3 of the girls last night and gave Epsom to another. one seems alright so I let it be and found one is a hermie, so bye bye to him/her. Waiting now to see what way they react and will check soil pH over the weekend. After that its just wait and see I guess

Slipon · Jun 27, 2012

yea best of luck ...

Im fighting PH isues now (a bit low) runn off is 5-5,5 insted of my normal 6 (use 6,5 to water with)

guess that also could be the reason for them small bud leaves curling ?

some did suggest me to repot .. but mehhh in 7 gallon pots .. 5 feet tall in total .. cant even remove em from my grow room with out takeing down my zipper dooor Im sure

but got a idea last night (did it around midnight .. did take a hour and I had to get up for work at 5 !)

my very own 2 pot soil grow system

did just use a old 4 gallon pot .. filld it with the rest of my light mix .. gave it some light nutriens (P/K and micros and a tespoon of epsom salt)
and cut a 4x4 hole in the big pot and put it in .. was about to tape em together .. but did remeber sumthing about air .. and ther is`t much/any light getting in ther ..

lets see .. only did it to one of em .. the most bad looking one ...

also got some Maerl to day (Coral Reef lime) to get the PH up in the other one so I dont have to do that agin ..

Maerl:

sorry to hear about the ****ing guy ... is it Femi seeds ? or did it just hearmy "natrual" ?

best of luck with the rest .. keep me/us updated and I will do the same .. maybe together we can learn

just transplant, and lime the soil while yer at it. 2 birds.......1 stone.

Dont worry man shes gonna be okay

just trim the bottom leaves there really not that important at the point your at anyways

stonerpaddy · Jun 27, 2012

Just had a look there anyway and the ones I flushed last night seem to have improved a bit. More than the one I gave the Epsom to anyway. Thinking about it, it makes sense cause I upped the nutes from 2ml to 4ml two weeks ago. Extra nutes probably swung the pH. Hopefully know for sure Sunday/Monday. I have the lime aswell to raise the pH so should have this sorted.
Nice to see you were struggling with plants last night too. Moving 3 plants down a stairs and through the house to flush them out was not as easy as I thought it would be! They get heavy after being soaked!
I remember seeing something resembling you solution with the extra pot. Cant remember it exactly but the idea was that the roots grew in to the newer soil. Cant hurt to experiment anyway, thats how we learn.
Couldnt get the seeds in fem. It was taller than the others and closer to the light so I think just stress
Probably gonna trim the leaves as well. Some are too far gone to help now.
