Diagnosis please

Hi all

I wonder if someone would be so kind as to tell us what this year's problem is. :)

We started, in April, with eight plants from seed. Four were Guerillas' Gusto seeds left over from last year and four were new Amsterdam Gold seeds. All are being grown outside, here in Spain, and four males were culled leaving us with three AGs and a single GG. They were pinched out and potted up as necessary.

After their first potting on I started to feed them with half a capful (about two teaspoons) of Bachumus ecohemp-c in a gallon of water once a week and, around July, I also began to feed a teaspoon of epsom salts in a gallon of water once a week. They were given plain water as necessary when they dried out, which would be be once a week at most.

Everything was going brilliantly until about three weeks ago. I then noticed brown blotches appearing on one of the AGs so it was moved to the other side of the patio to isolate it. The blotches slowly spread up the affected plant and now seems to be starting to affect the other AGs, though the GG seems to be perfectly alright and unaffected, if a bit leggy.

I guess, as it's only affecting the AGs, it's got to be a nute problem but don't know what it is that I'm doing wrong.

Any free clues would be greatly appreciated.

TIA

looks like u have mites too on the left plant? is that loads of little white specs on the leaf? shame its not a bigger pic..

Thanks for the reply. Thanks also for that chart. That's brilliant and I hadn't seen it before.

The white spots are water marks from where the plant gets splashed when the patio gets washed down. I've just wiped them off with a cloth.

Sorry about the pic size. I wasn't sure how big to post so reduced it. Here's a full-sized one. I certainly notice the tracks on the leaves so it looks as though *something* is having a little burrow around in there. The problem started as those brown spots of the RH-most fan leaf and spread to 'burning' patches and on the leaf edges.

Cheers

well im not clued up on plant problems yet i just got the chart too, someone else shud post cause id be mad to guess.

> someone else shud post cause id be mad to guess

I was *hoping* someone could tell me. I certainly didn't want to kill them off by guessing what the problem is.

id flush em out anyway with plain water i know that much.. ive never heard of the breed.. and id get a whole bunch of different nutes n boosters anyway for wen stuff does go offkey.. like seperate N-P-K's so u can topup 1 nute without overdosing another..

I was hoping that someone would say that - as that's what I've been doing. :) Sadly, it's not making a lot of diference and things are getting worse.

The fun part of that is that we live in Spain. Looks like a browse around a garden centre with a dictionary. :) The fert we've got we bought from the local headshop. It *should* be ok.

As I said, things are definitely worsening. I've taken a pic of each of then other two plants and I'll post them up to a new thread.

Cheers

yeah well after flushing id presume they need feeding again they look pale even if they were overferted before. maybe epsom salts every week wasnt good either i duno... u dont needit if the soil is ok and its not overferted.. ?.... u best check your soil ph aswel i think? somehow! test kit, electric meter or wateva.. dont forget foliar feeding is good too but in weak doses..
