As the title says I'm having trouble with two of my plants, it was three but the problem fixed itself on one of my plants. I switched the lights to 12/12 on 7/18 and has still not shown sex yet. I checked the ph of the water a couple days ago and was a little lower than 6, maybe 5.7-5.9 on the bushier plant. I think I corrected it today with higher ph'd water. Checked the run-off after doing so and it was around 6.3. I will do it again next watering to raise it up a little more. The ph on the plant that "fixed itself" was in the normal range last time I checked it and is doing good. I'm almost certain it was/is a Ph problem. The lower leaves started to turn yellow on the tips, then moved in to around the veins and then they started to turn brown and die off. It started about a week and a half ago and thought it was normal cause it wasn't spreading, well it started spreading a couple days ago and I want your guys' opinions on what it could be. I vote ph which is causing lockout of various nutrients soil: MG potting soil Only given nutes twice because the soil is time release. never had a problem with burn even as a seedling Never under-over watered You can see the current grow in my sig, thanks for reading! PS; the solo cup grow is for experiment purposes only lol
Sap is correct, go to my blog and read: http://forum.grasscity.com/blogs/vostok/28546-nitrogen-deficiencies.html, consider foilar feeding,2-3 times a week, although you are freaking out, it's not that bad, next time stay sharp, too little (N) is by far better than too much (N). peace "V"
I've given it nutes a couple days ago, nothing has changed.it's been almost two weeks since switching to 12/12. Why would my other plant be fine after it was doing the same thing? Wouldn't you consider Ph part of the problem since the one that is fine now has a correct Ph balance and the one that isn't is Not on the the correct level. Since I haven't been able to sex them yet, wouldn't that be too much nitrogen or Ph lockout?
I kinda figured that, it is spreading up the plant quite fast though. You didn't really tell me something I didnt know but thanx New growth is doing well as long as I can fix this problem
