Brown Spots

**johnny1234** · 05-30-2007, 05:37 AM

Of the four leaves on my plant, two have like crispy, shriveled leaves with yellow faded splotches and definate yellow tips. i havent used any fertilizer (apart from slow release fertilizer already in soil) yet because they've only been growing for a week and they are small pots. i have HPS lamp 30cm from the plants which seems to heat up the room a bit. but the other two plants in the room seem fine. PLEASE HELP!! thankyou

The slow release ferts are probably the problem.Repot today in a good soil with no ferts!

but the slow realese ferts come with the soil, i think they must be very weak. whats wrong with a bit of nutrients?? I'm confused

Its the ferts in your soil..Repot more grows have been ruined by using this type of soil. If you do some reading on here you will see that others also say do not use soil with slow release ferts!

I have had problems with brown spots looking like rust all over some leaves. They normall start off as light green/yellow spots which turn brown. I have found that it seems to be mg and adding some epsom salts to a water prevents them getting worse but they never recover. I am about 1-1.5 weeks from harvest and it doesn't seem to have caused any major problems from what I can see.

Ok, thanks for your help. I'll go get some soil with no slow release ferts now. should i use normal fert straight away or wait abit?

Don't use any ferts yet. They should be about 4 weeks before you need to use some else you will burn them.

Over-watering, causing a lock up of nutes

Fox Farm nutes are good, spiders are bad, use neem oil.
