Man these plants are giving me fits! This yellowing leaf problem, first a mother that i revegged, then my for plants in dwc, and now my clones from the reveg. They all keep getting this. What am i doing wrong? My ph is almost alway 5.8-6.1, using gh nutes, cal-mag at 200 ppm with ro water, silica, no nute burn, plants had a case of brown algea/root rot that is cleared up well. I thought maybe that was issue but a mother in soil has these leaves also, and 3 out of 9 clones from the mother have it now too. Its lower leaves, and progresses from green and lush to dead in 3 or 4 days. WTF!
It looks like a disease to me, I am no expert in growing of marijuana yet by no means, but I have seen this from customers plants when I worked at a greenhouse Sent from my iPhone using Grasscity Forum
Each time you use the same plant/soil that contained a diseased plant inside of it you will continue to pass that on the next time around. Also if the mother has it, all clones will most def carry it as well... I would suggest trying to narrow down what exactly is causing the mothers issues Is it soil from a previous grow? Have you had this happen from the mother? (Yes) Then the issue lies at home, momma plant Sent from my iPhone using Grasscity Forum
I think you have a fungal infection. folier spray with compost tea will probably help. Twas Ever Thus!
Thanks hack! Well, as it turns out i think it was totally my fault this happened. It started out with too warm of res temps, led to brown slime and root rot on my dwc plants. The leaves are doing that because the root rot caused every deficiency under the sun, and i was feeding the mother with the water from the plants (mother is a revegged blueberry in dirt) so i actually caused the mother to get some root problems too. (At least this is what im thinking, please correct me if i'm wrong) And yes the clones came off the mother hence their problems. But, i just took these 9 clones, and they rooted in 4-5 days, so idk if they are really that sick? Any thoughts? I will be posting pics here shortly, i just need to get my res changes done here and do a little work in the house first. Thanks so much for helping me. And please feel free to correct my incorrect thinking if there is any there, i'd be pleased to know it lol. U say u saw this in others plants? What was the cause, and if u think it is a disease, is there a name for it? Black spot fungus is what i was told by a guy earlier, and he suggested i spray em with sm-90. But then i read some more on some root rot threads, and those spots kept showing up, and all the deficiencies stacked up on each other seem to produce this leaf pattern. The new growth is just fine, except for a lighter green in the centers of the new tops, but they quickly darken back up when they open up more. Lots of new roots and growth except for my trainwreck, i dont think she is gonna make it but i will hold out hope because she started growing roots again today as well, (after a 200ppm jump in nute strength) i was afraid to over nute after the root rot, thus not helping with the deficiencies. But please give me whatever info you can and correct me if i'm making a mistake, this dwc has me learning all over again how to grow plants lol.
I still believe its a fungus because it is affecting the one in soil too. deficiencys wouldn't transfer in the water but fungal spores would. I would treat it for fungus. it will not hurt even if I'm wrong. Twas Ever Thus!
what would u suggest for treatment? I have sm-90 and lots of nutes, And a buddy told me to try Actinovate.
Heres the veg room plants Big Bud Blueberry 1 Bluebarry 2 TW All these plants are the exact same age as the plants in the previous post, a have just been giving them very little light to keep them from getting too big too fast. They are backups and next run
idk exactly what u mean but i'm running ro water, so it should all be zero. My 35 gallon ro tank ends up 3 ppms usually.
Ya i was wondering, he says he sees that in his outdoor gardens, and uses actinovate a few times and it disappears for a while, have u ever heard of it? I guess its organic and safe for all food plants. Thanks by the way.
never heard of actinovate but from what I read its like a compost tea spray in that it is bacteria that do the work. I do know that these work so actinovate should be similar. It will take more than one treatment two or three days apart. I hope it helps. Twas Ever Thus!
