one thread to rule them all. you flood the forums you push down someone who may not have gotten help.

flush and quit feeding the nutrients at that size.

just flushed them the night before...thats what they looked like the next day! sorry for so many posts tought i could upload only 2 pics per post?

Couple more questions for ya.
Is the top layers of soil dried out when you apply more water?
How much are you feeding them, nutewise?
What's the soil consist of, or what brand and make is it?

P.S. 2 pics per post, then do multiple posts in 1 thread.

Your soil is too hot (high ph), too compacted (add 1/3 perlite),root bound (transplant it to a 3 gallon pot min) and overwatered.


New soil of 1/3 perlite, 1/3 organic compost, 1/3 pro mix will do the trick. Let your babies dry out and ask for water before flooding them again..

When you add new soil, for the love of jebus, don't start pouring fertz on them.. wait till the lower leaves start to yellow or go lime colored first.


READ THE FAQ IN THIS FORUM. YOU KNOW VERY LITTLE ABOUT GROWING. and 1 post only please!

Ha, right on.
I was forming similar observations myself, CD

okay thanks for all of your advice will get stuff today...btw is there any way i can get away with using 10" pots? im growing using this setup

so it's under 4 1750 lumen cfl's and 2 2700 lumen cfl's...
so space is at a premium and everything is low stress bent!

Think you might be over watering.Wait till your plants start to drop a little before watering.Your pot should be realy light to pick up before you water allways.

that second photo looks very similar to potassium deficiency... but your plants shouldn't be having that problem so young. Have you been going nuts with overfeeding fertiliser? If you have you may have made your soil toxic so flushing helps and don't feed nutes for a while. You may also have soil PH problems which result in nute lockout. If you've been using straight tap water along with fertiliser this can happen (nb tap water from my tap comes out as 7.7... I have to use "PH Down", available from most hydroponics stores, to get it to 6.5). Get a cheap PH test kit and test the run off (or better still a PH pen... a great investment). If you really want to get technical get a CF meter to measure the nutrient content of the run off (though I suggest you ignore this step... I am just saying it's another way to measure toxicity). Some plants don't like a high nutrient content (what know as high "PPM"). As far as overwatering... yeah I agree with Dave. you could well be doing that. As Dave very wisely says... you need to learn to feel when the pot is heavy with water... and when is light (also top soil normally dries out when it gets dry which is always bit of a givaway) G'luck.

BTW.. I realise CD pretty much said all this in simpler terms. If you have cruddy soil... get some decent stuff. Biobizz Allmix, foxfarm etc etc. I do disagree about 3 gallon pots though being hte minimum (I've seen guys also grow in 2 litre coke bottles with autoflowers). I grow v happily in 1 gallon pots. Depends what size plants you want to grow. Smaller pots = smaller yields and the plants require more feeding. Cheers.

i think it could be potasium or sulfur needed
