Hi peoples, A friend of a friend has been having a small problem with one of his Sweet Tooth 3 canna plants. He was growing a few in smaller (maybe 3 liter pots) and all was going fine, was looking green and fresh. He knows he may have left the STs in the smaller pots for abit longer then whats recommended but i dont think they got rootbound as there was they where looking very fine.. Annyways, he ended up repotting them into bigger pots a week and a halfa go or so, and all was looking fine, but after a week or so in, he started noticing the older parts of the stems (not the main stalk) but more the branches and leaf stems started to turn purple and and the stem…

Hi all, Im growing 2x beauties, 400W indoor, not far from finishing I have started to notice a few leaves beginning to curl and thin out (they may have just grown thin) and a couple of leaves are starting to get black tips? I don't know if its normal but a lot of leaves seem to be yellowing and falling off. Theres still a lot of nicely coloured ones and the buds are looking healthy, getting nice and thick on top and more turning up at the bottom I did notice a couple of little blue flies as well but theres only a couple in there and i have a small homemade trap (banana in a glass covered in clingfilm with little holes in it) which has got a few of the ones i d…

Hey all, I have a drama... A grow tent that I bought has sooooooooo many problems with it - mainly light leeks, that my plants look like they are in 2nd wk of flower instead of the 6th week like they are. I have used so much gaffa tape it is ridiculous and the tent is going to the tip after this grow - but if I can manage to seal it up - will the plants finish properly with an extended flower period?

Hi guys, well onto the 2nd grow. I just transferred 3 4 week old seedlings into a DWC system using phytoflake as the medium with some clay balls on top. Since transferring from CFL 150W to the new system under to 600W HPS they have been looking really droop and sick. The leaves were looking quite dry too, and yellowing. Is this an overwatering issue? I have them on 10 X 30 minute waters a day In the pics I have given them a foliar spray with superthrive. Any advice would be greatly appreciated! Cheers

This is a new problem to me I have a few seasons under my belt and consistently yield excellent results. I scored four clones so I put them in a fully decked out grow tent (400W hps air cooled, 150 Cen Fan, 150x600 Carbon Filter, 4 x 15 ltr dbl pots in a Recirc Sat system) The tent is well controlled and stays between 25- 28 degrees with 45- 60 % humidity. The nute tank is 50 ltr and has pump, heater and air stones, water temp set at 22 degrees. I use rain water and set to an EC of 1.2 approx and PPM 0f 800. Dutch Master Advance Nutes with silca an zone added. Medium I use is perlite with a feed schedule of 15 on 3 hours off... All this to me seems fine but the cl…

Hey all. My poor little bubblegum sprouts have been through a lot this week. I had them set up to be fed every other half hour, and as such they showed signs of over-watering. I stopped watering them for almost the entire day, and now have them set to be fed 4 times a day, for a half hour each time (half-hour units are the smallest I have to work with). Now the poor little guys are getting more burnt looking spots on the tips of their upper leaves, and show limited signs of recovery from the over-watering. Now I'm going to be gone this coming weekend (plus Monday), and I don't have anyone to entrust with their care, so I'm stuck with the timers. I'll post pictures, but th…

Hey I think while I was away with the system running slower than usual, the water was a little too still for a little too long in the bottoms of the pots... The roots obviously hang in this remaining solution... When I first noticed the discolouration of the roots, about a week and a bit ago, because it was all evenly coloured and not patchy... I didn't think too much and dismissed the possibility of problems... Being only my second crop and first attempt at revegging, I knew FKL about root rot etc... I'm growing in clay,recy,using canna nutes- PH 5.8+ EC +- 2 feeding half an hour every 3 hours. I've gone through the forums and found ref to Hydrogen peroxide, ox…

Hey all. My sprouts have been doing great for the past couple of days, but I took a peek in my closet a little while ago, and the leaves look very droopy. Doesn't look horrible, I figure a little drying should fix them. I'm thinking that having the drip rings on 30 min/ hour was way too much. I turned the system off for the night (California time), but what should I have my timer set to in the future? Sorry for the constant problems. What can I say, I'm new to this.

Hey again. The brown spots on my sprouts' lower leaves have worsened slightly after I transplanted them to their current Hydro buckets. I seems to be isolated to the very tips of the bottom leaves, and I think that the fact I kept their BioBizz enriched water sitting in a jug might have contributed. The water in the bucket system has half the prescribed nutrients and has the pH balanced around 6.3. I picked up some antifungal pesticide today, says it's fine for garden fruits, vegetables, houseplants, whatever. On the bottle it says the active ingredient is "Clarified Hydrophobic Extract of Neem oil". Is it safe to spray that on a plant I intend to smoke? Any help at all w…

Hey all. I've got half-month old Bubblegum sprouts that have been growing beautifully in rockwool, and just today I noticed what looked quite a bit like burn marks on the tips of the leaves. Did I have the light too close? It's just a 60 watt fluorescent thats been hanging maybe 3-4 inches (8-10cm) over the tops of them. Moved it to about 6 inches (15cm) away today. Could I have misdiagnosed the issue?

hey so im running two plants at the moment, one about 2 weeks older than the other. They are in a cupboard with a 400W HPS bulb, running on 18/6. Im using Greendream 1 (one part flairform nute) at an EC of 0.7 and a pH of roughly 5.5 (can't be exact because im using a colored indicator mix). The largest plant has purple stems and some pretty nasty necrotic patches on the lower leaves (which i cut off only to find that they then appeared on the previously healthy parts of the leaves) but it's now also getting some on the tips of the newer leaves. The younger plant is also showing some necrotic patches on it's leaves with a little bit of yellowing. I just realised yesterda…

hi can anyone tell me how to effectively use fongarid in a recirculating system with rockwool instructions say 2gr per 2 litres of water added to soil. so i mixed 10gr in 10lts of water and drenched each slab (media) with 1.5lts and allowed the runoff to circulate back into the nute tank. does that sound ok? also can i add h202 when using fongarid? i know h202 is non-systemic wheras fongarid is systemic so i figure it would make a good 1-2 punch for pythium
