I found these today, they only seem to be on very few leaves and these two leaves were the only ones with lots of them on them. Do these pose a problem to my harvest, how should I get rid of them? Peace F D L

Hi! This baby is my little guinea pig so i'm not to worried about her but still it would be nice if she reached maturity. Initially i think i gave her a bit too much nutrients "nulife power gro" as you can barely make out in the pick the tip of the leaves are slightly yellowed and curled up. What worries me is that she has such a light shade of green. After i gave her too much nutrients next wattering i skipped the nutrients and halved them after that. Any help would be greatly appreciated. Medium is organic soil with clay balls and i have added a little bit of sulphur to the top of the soil. 400w hps and a decent fan which keeps the temp on the plant to a decen…

Beneath are my girls that I've had outdoors since about October last year (yeah I know a bit late) they've been flowering for about 3 - 4 weeks now, and since flowering I've began noticing the slow yellowing and eventual dying off of all of my girls leaves from bottom to top, at the rate theyre going there won't be any leaves left by harvest , what makes no sense is the top half of the plant looks healthy as, plenty of hairs and crystals everywhere. Here are a few stats on my grow 9l pots, watered with PH adjusted water daily or every second day depending on soil dryness, I've ferted them a few times during their life, every 2 weeks with Yates multi-nurtient plant food …

Hi group, Some basics to start - 50litre pots run-to-waste - Coco with thick layer of clay balls at the bottom - Auto-feed 1 min twice per day, don't always get 10% run-off - Ample air-flow and oscliating fans in the bedroom - Lights are about 15/30 cm away from tops (some longer branches have shot up) - ec .6 - 1.2 (reduced from 1.2 due to burning, seemed to thrive at .6 in veg) - Ph 5.8-6.0 feed tank, run-off is 6.8/6.9, pens calibrated regularly - Flush weekly with ph adjusted water - Currently in week 3 of flower - Plants look mostly healthy, but patches of problems like this are coming up - No evidence of bugs (i've looked under leaves) Any ideas?

Recently i stupidly changed from coco to clay balls to save myself a bit of watering. Had some small plants in coco and gently rinsed the coco of the roots then put them into pots with balls watering them for 15 mins of every hour. Problem is that the water got real hot as it was in the room, and the black feed lines got super hot- Result- Seriously wilting plants and yellowing of the leaves as they die. I can only assume that the roots were burnt by very hot water. I have tried to flush them out and changed the light cycle as so they are not on in the hottest part of the day. Have better ventilation Have lowered ec t0 1.2- ph 6.3 have kept pumps running contiuously Ha…

i have on a few plants not all and not all buds, a little ball kinda like a seed growing but it has 2 red hairs coming from then, i am unsure as to weather this is a hermie or what it is? the plants are growing super healthy and its not really affecting much, they are not appearing in clumps, but some buds did have two or three in each bud, and other buds are unaffected. i can get some pics up if it will help you identify. never had to deal with a hermie b4 so i am unsure as to what they really look like...thanks..

Okay, i'm really stupid, I veged the girls for to long without realising it. I know it's a dumb problem to have, but it's a problem none the less. I switched them to 12/12 yesterday, but looking at it, it's going to outgrow the head space they have very quickly. I've never had to tie down during budding before, any tips you guys could provide would be great. Do I just tie down the tops? will it make the buds retarded?

The girls are entering their 6th week of flowering and whilst the buds look ok the plants are looking a bit ragged. Last night I thought I saw a tiny web on the very top of the plant. I touched it and there was like a silky strand stuck to my finger tip. There seem to be very tiny brown critters running about on the underside of the fan leaves but not many at this stage. They are on some buds too. I have read plenty on spider mites here and elsewhere on the web. But even with a magnifying glass my eyes are struggling to see the mites. Since this is an emergency I’m trying Yates Natrasoap. (biodegradable and non residual) and no withholding period. They claim it kills sp…

Anybody run into this problem? They are two Chemstar clones from out bush before the floods, they are off different plants but both show the same symptoms. =upwards curling of the edges of top leaves and growth tips. They are the only two clones of the 28 from out bush to show this deformity, they are also the only Chemstar clones . Any ideas? I had something very similar on a Skunk#1 clone a while back but it has grown out completely in bloom and was never quite as bad as these two.

Hi all, I'd been having some problems with my babies that resolved after reducing nutrients. However, now I have some other issues coming up. The leaves and branches are dying off from the bottom up, and it looks like it's a Ph problem. See photos. They have been growing about 6 weeks, just turned back, ec is at 1.1/1.2, ph 5.9-6.1 (and I check it daily and readjust it if needed). I dipped the pen in the coco and the top reads around 6.3, but the ph of the run-off was reading 6.8/7.0. I've flushed twice in the past week with Ph adjusted water and it makes no difference to the Ph of the run-off, still reading 7.0 after six flushes today alone with water adjusted to Ph of…

hey guys just a quick question, my seedlings are only 2 weeks old in coco-peat and perlite mix 70-30 roughly, they've just started getting their 3rd proper leaf set and i've just started using nutes about a week ago (2ml as it says on the bottle for seedlings) they started loving it bursting with life and now going yellow, now would it be that i just need to flush or coz im not using coco nutes? thanks guys
