hi all, got a few seedlings which are almost 3 weeks old,growing in soil/perlite mix and under 3x 24w "natural light" fluoros,6 inches from the tops. Have grown seedlings like this before. anyway, one of my M60 seedlings just stopped growing at the first set of 3 fingered leaves (10 days ago) and the leaves curled under themselves in a really tight roll! tried raising the light a bit, have flushed a few times but still no change. looking thru a magnifying glass at where the new shoots should be i can just see some white bump/node things, almost like immature pre flowers! but these arent growing either? all the others are really happy but dont wanna lose this one as i…

This I hope is good enough to show the malformaed leaves. It is AK - "a gratious gift" She is lookling just fine. OD'ed on nutes slightly for aa short time but is ok now in that regard. I suspect a high PH may be the cause but will want your opinions. When inspecting the leaf formation I first thought a bug eating them. I could not find any and thought it could be thee result of too high PH. On recall I think I have been feeding at EC 1.8 & PH 6.2 - 6.3 - could this be a simple problem like PH ? Thanks for your opinions peeps.

I have a run2waste system with a 200ltre barrel. I use: - Advanced Nutrients (recomended ph of 5.6) - au60 root repair - fulvic acid - silica majik - nutriboost - advanced nute big bud (powder) I set the PH at 5.6. But when i check back couple of days later it's up to 6.2 -6.3 Whats with that? The Advanced nutes website recommends using nitric acid to bring PH down as the stuff most ppl are using reacts with some of the nutes. I might try it out as i'm putting quite a lot in to a 200ltr barrel, and I'am interested if anyone has experience in this

Hey there. I have 6 plants in coco fibre using GT nutes. Two of the plants are blueberry and the tips of the leaves are pointing downwards. It's only recently that they've been doing that. Maybe a week or so. Can anyone help?

Hey everyone, I am at the end of week 4 flowering & have been battling fungus gnat for a little while now, which seems to have taken most of my attention as I failed to notice some small male flowers(only single ones by themselves at nodes usually just under forming buds, there was none on branches) - some of which have opened!! I searched & carefully cut them off, then gave them a good spray of La Femme and moved my light further away as not to burn them. Then I smoked the male flowers!!!!! Its really easy for me to get stoned atm!! So what else should I do - keep cutting off male flowers as I find them?? Cull the plans now & start again?? Or is there …

If the leafs are curling up at there ends, does this mean too many nutes?. Or lack of water. I dleiberatly havn't watered them for 3 days to stimulate root growth etc. Making sure there's a dry period in between.

Hi, I germinated some seeds, potted them in some coco, then about 5days later the stem on the babies choked, shriveled up. Died. This is something i noticed a while ago when my cuttings died the same way. It seemed pythium+root rot was the cause. So this time i pulled it apart and didnt see much wrong with the roots, although a bit yellow. No sign of rot. So i tested the ppm/EC of the coir it was 1.5-1.6 EC diluted!!! with 100mls of pure water so potencially a good 1.9 - 2.0 EC @ root level. Damn i forgot to flush the coco coir clear before using it. Because Im a bit rusty,what is the shrivelling up of the stem is due to? Could it be something else as well?
