alot of my upper leaves are beggining to turn a light shade too, what is this a sign of? a deficiency of some sort?
You wana hit me up on deficiency advice here!lol! I like to chill in this thread not worry.
You got to realise that i dont know that much just what i can find out on the web and from very good growers and studying my plants. I see lots of growers main problems start when they flip em to flowering, only two things that change are ferts and light and well light never hurt no leaf unless too strong and with grow lights thats rarely the case so i attribute a lot of it down to the high P/K we just threw at our plants and when there first flowering and for a couple of weeks there are not really wanting a high level of P/k like when there in mid bloom. I guess we would use this period to transition to more dominant P/K levels by week 4 to 5 and not week 1 to 2!
If this sounds like you then by all means give this some consideration, i only know what i know but tomorrow i may find some better information to tout!loL! It works for mew anyway.
dont no m8 i look at mine and they look good get a pic up on here for all to see
This is the best option plus some details, yellowing at the tops might be iron, manganese, zinc and possibly one or two others but not nessecarially a deficiency, high P/K can cause lockouts in these and other nutrients. Maybe find a thread called 'Never ending abuse of Phosphorous' by Uncle Ben as he explains this as well. Hell you might still be vegging idk.
My biobizz bloom is NPK 2-6-3.5 or 4-12-7 or 8-24-14
My Biobizz grow is NPK 8-2-6 or 16-4-12 or 32-8-24
So not the best NPK for marijuana and feed just the bloom in flowering and damn thats a lot of Phosphorous plus check out the veg grow, could do with a little extra Phosphorous.
My Biobizz fishmix is NPK 6-2-4 or 12-4-8 or 24-8-16
And hence you can see why people prefer the fish mix over the standard grow, 24-8-16 is by far better than 32-8-24 for the veg period although biobizz is a two part nutrient, no reason not to sweeten up the grow with some bloom in the veg period thus creating a more harmonious NPK for the veg period as we do the flowering. Ive not tried this yet but will be soon as plants look like they get a little too much nitrogen compared to Phosphorous in the veg period.
Peace and again sorry for mumbling.
