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

I found this on the Amsterdam Seedbank and wondered if it is true... I have a few balls happening today on my WR, but they only have a day or two until chop so I'm not stressing. I know that they have done this due to the stress I've had them under lately but I am wondering how true this statement is in your opinions. Also how long does it take a pollinated female to start showing seed - a week or so? Jimbo

Hi all, I hoping someone can help me with some experience on this problem .... I cut my clones from flowering plants ... these 'mother' girls were all making seeds and have now been cropped .. the problem I have is that it seems all my clones have jumped right into making seeds again and I can't understand it .... they started making seeds almost immediately ... the question I have is ... do clones taken from plants that were seeded, automatically go into seeding when they are put into flower? I vegged all the clones for weeks before turning them to flower and it all looked fine until about 10 days ago when I noticed seed pods all over the place. Not only are there l…

This is by far the biggest and most healthy looking(to my amateur eye) seedling I have grown thus far. Does it look healthy to you guys? It would be 2-3 weeks old by now(counting the first day of soaking as day 1). The soil composition is a mixture of seed raising potting mix, peat and midrange(not premium) potting mix. I was experimenting with different mediums so I cannot tell you which is which It has been given one small dose of tomato fertiliser(way less that the recommended amount) and a touch of epsom salts. It has been grown under a large CFL (equivalent of 500W with 6.4k light output) with a few normal smaller CFLs in a mini-greenhouse indoors. Th…
