My 2nd plant


Thanks

Are you using a soil-less mix?...cause if not your plants are nute burned i'd say. Your plants should never really be fed untill they're about 3-4 weeks old.

but it hasnt happened to the 2nd plant and that has been in the same conditions and feed the same as the other.??

whats your humidity and ph.

i dont monitor my ph and my humidity is 40%. any help?

it looks to me like your ph is off and your getting stuff locked out,it may even be heat related.

in those small pots it easy to get salt build up.

i dnt think its heat related because my place ive got them in is very well ventilated and they are being grown under a 125w envirolite blue, and a 4000k 250 mh.

how much are you feeding them and how often?? it dosent look like burn at all. it looks like they need more nutes if anything.

i feed every 4 days natural bottled water mixed with 2ml of bio bizz per liter (recommended 4ml per liter)

what are you using for growing medium?? Soil, Hydro, coco??? What kind of nutes are in the soil?? I say feed every other watering they are just about ready for full streangth nutes now.

ive never used bio bizz,but it cant be salt buildup if your useing bottled water,check the nutes in biobizz,maybe it is lacking one of the micro nutrients,is bio bizz a stand alone feeding nute,i would use some pure blend guano for veg but be carefull it really plays with your ph.but then again bio bizz might be all you need just more of it,i dont see any nute burn but that stuff shows later so be carefull.

hi, thanks very much for all the replies. I need to know what i can do at this point to help my plant. Its northen Lights / Shiva from nirvana i really want to see it happy.

I am using normal soil mix from walmart(AsdaUk) with vermiculite. When i move to new pots 2moro i will mix with perlite and vermiculite, i also have pebbles(any use with soil
?). what can i do ????

Feed them a little more! not alot a little see if the yellowing stops. The leaves that have yellowed will not turn back green but it wont get any worse. Do you find that your plants have slowed in growth in the past week, if so get feeding them more. Some strain are very heavy eaters some not. You will find a sweet spot with some practice and when you get to know your plants a little better. I am still sticken with you need more nutes in them

so what should i do now, get the bottled water, add the recommended amount or more or less?. because ive been adding 2ml /L should i add 4ml(recommended) or more than that?. Im confused. The other plant has had the same doses and it dnt look lyk that.

Next time you water, feed them the reccomended dose or a tiny bit less. Start feeding more often, try every other watering. I am possitive your plants will start growing faster and the yellowing will stop. Now if you notice brown spot on leaves thats a sign of too much. but if you follow the instructions on the back of the bottle you should be just fine! good luck. I am glad to answer any of your ?'s

you might want to put some dolemite in your soil mix to to stabalise the ph.

get them some nitrogen boost!

Agreed at least get a Cheap soil PH meter. it will give you rough idea what your looking at

I would actually flush your plants first before adding any more nutes or anything for that matter. Leech your soil of all possible salt build up and start over with the biobizz. The rason i say this is more times then not people add more food...and sometimes it's not that at all. Just a tip before trying to fix any problem at all...flush...then assess.

Does your soil contain any time release food in it?

Try going to one of your local garden shops and look at getting soil-less soil...i think it's the best to start any plant off in...that way you have control of what food is going in there from the beginning.
