Separate names with a comma.
Although there are a few spots and some yellowing, it doesn/t look like calcium or magnesium symptoms particularly. Your idea of potassium is...
You probably do have some lockout or whatever causing the leaves to brown like that, yes. But it's a long way from dead. You should flush it....
So the answer is, yes but why? Before LEDs became reliable and affordable (in the last few years), CFLs were the common 'budget' alternative to...
I see a lot of cardboard and maybe a space-blanket. Looks like a light burn/temp issue, although it could be a pH problem as well. Include a pic...
I agree with the comments that it's a bit late to do anything about them now. If you had removed them when they started to show, in theory the...
If you have the MH then I would seriously consider switching to that instead of using more CFLs. The electricity cost of running the 300w MH will...
All seems perfectly fine. Imagine looking at two new babies - this one has more hair, that one has fatter fingers, this one has a rounder face,...
Take a look at the FoxFarm feeding schedule. Seedling & week 1: 350-420ppm Week 2-3:1500-1800ppm Week 4-10: 1700-2100ppm Based on this you are...
To me they don't look like they're suffering from an overwatering problem. The lime-green colour can sometimes be due to rootzone issues like pH,...
nice growth, but they look a very pale colour. I couldn't find any posts about what your problems were, but they look like they are in need of...
As well as being really dark green, which can be fine, the leaf tips turning down at the end and the smaller under-leaves clawing, are signs of...
I think the leaf damage looks like tears/handling damage. Do you have a cat/dog? Or maybe when you've move them and caught them leaf on...
Usually watering evry 2-3 days is a bit too often, and means you are either over-watering them or your pots are too small. You can protect...
Rather than cooling the room, just get a small/desk fan blowing on the plant. That will help with heat from the cfls. Looks like...
Curling up at the edges does usually indicate heat stress. If your thermometer is on the floor in the shade, that might not give a good...
The plants look very healthy. The nute burn you mention is very minor, I agree it is probably just from the soil. You can probably add some nutes...
If you are a natural green-thumb, lucky, or even just incredibly lazy with a good soil mix, autos can do great. But yeah, some bad luck or a...
Never used KindSoil but from the website they say you want 5lb of kindsoil per 5gal pot, then cover it over with coco/perlite/soil mix, so it's...
This is basically a hydro medium - it has no nutes in itself, it's like coco but less environmentally friendly. Also, peat moss can get very...
Yeah so next time try a generous 7-8g of maxibloom per gallon (40% increase on your usual), check the ppm for reference, and use that see how it...
