I just want to add what the pros are saying here. When growing hydro, the sweet spot is 5.8 pH as you mentioned in one of your previous posts. Soil or peat is much more forgiving and plants will thrive with a pH between 6-7. Peat especially has a way of balancing things out nicely. By the way...

In case anyone was curious about that little plant missing a Cotelydon...

Ahh, okay. Yeah I know that you're saying now. Well, it will be interesting to see how she turns out this way. Incidentally, a third true leaf has started to grow in place of the missing Cotelydon. Thanks kindly for the reply.

Well it would be interesting to know how it got stressed. I sprout all my seeds the same way. The others that sprouted are normal. Just this one isn't.

Hope everyone here is doing well. I germinated a feminized auto critical seed and noticed from the start that it only has one Cotelydon. To be honest, I've never seen that before. The little plant is taking off in growth, so there's no trouble there. Has anyone here had any experience with this...

I have had great success with Blueberry autos, and the smoke is plenty strong. I even had one guy tell me its nuclear as he was having some sort of panic attack and saying my weed is too strong :D I say that if you have the need to grow autos, then go for it.

What's the temperature of your water? Algae will only grow if the water is too warm and the area is subjected to some kind of light source. If you single those two things out, then you'll know its something else. For instance, in one of my hydro buckets, the drain tube (clear tube) on the...

Roots are looking good. Strong white... Little tint of red/brown from the bacillus Amyloliquefaciens. But not using this anymore This is the bloom booster I am using (click) I guess it's called something else now. The directions say 3-5ml per liter of water. This week is the only time I used it...

My grow is on the 4th week... and it's stopped growing up. In fact, surprised me how short the plant really is.

Hey all, hope everyone is good. So I've got a little problem that I've been fighting during this grow. I set my pH at 5.85 or so, and the next morning when I check it, it's down to 4.5 :confused: I haven't had this problem before, I have always had to bring pH down. Using GHE trio (well Micro...

I changed a couple of things since this post. I decided to not put the pump inside the reservoir, so it's now inline on one of the hoses outside. The only thing in the reservoir are hoses, and nothing for nutrients + water to corrode. I replaced the thermoelectric peltier with a higher...

Well, the thing is that autoflowers can't grow with the lights on 24/7. Photoperiod only start to flower when the days get shorter, and there is less light. I say leave them at 12/12 until they are finished. If they are photos, and you add more light, they could stop flowering... But I'm not...

Are these autos or photoperiod?

Try to take some photos without the purple light or most people here won't even bother. The problem is the purple lights disguise everything and you can't really see what's happening.

This was exactly what I thought when I first saw the leaves. I've had a magnesium deficiency and this is exactly what it looked like.

Agree with Cboat38. I think at least this long (2 weeks). I still see pistils growing (white hairs). When those stop growing and start turning orange and start shriveling up a little, then you're getting close.

If anything, the solid yellow leaves are showing a nitrogen deficiency which the low pH would have caused. I do see some rust spots on some leaves, but that can also be from the plant not up taking the correct nutes because of the low pH. Might as well prune off those yellow dying leaves, they...

I wanted to say that a plant can have either a calcium deficiency, or a magnesium deficiency, but I have learned not to classify them together as one problem. From what I have learned here, there is no such thing as a 'cal/mag deficiency. For me, I don't see either one here. Perhaps the salts...

Well, first of all you're in the Hydroponics/Aeroponics thread. Second, that setup probably good for herbs and tiny plants, but not good enough for what you are wanting. IF you want to grow in water, not soil, then better start here. Plenty of good information for beginners here, you just need...

Yes, I built my own and its working good now. I am keeping water temps at 20 to 21 celsius
