Hey, my poor plant is looking rather down and i am not sure why and how to fix it (if possible). problem: lower leaves are losing their colour, turning yellow and wilting, my question, is this due to: a) Natural wilting of lower leaves (i've heard that the bottom leaves can just drop off with no problem i think) A lack of secondar nutrients (maybe iron, magnesium or manganese) c) Root problem, as you can see the plant has outgrown it's pot and roots are growing out the bottom. I would prefer not to transfer plant to bigger pot yet as i plan to cut out the bottom of pot and whack in ground in a few weeks and just want a healthy plant to survive the transplant. …

I have been flowering for about a week.... and almost that entire time my plant has been hell droopy.... look at these pics First day of flower: Today: I recently had to change my watering schedule to every 2 days instead of every 3 cause she seemed to be drying out much quicker. Also she has been under a bit of stress - after flowering for a few days I accidently left my light timer on alwayus on for 2 days. She's now had two full sets of 12 hour darkness so hopefully back well into flower... could that kind of light stress cause the plant to look so droopy? today I gave her a massive flush, then a feed with some nutes and h2o2, about 10 hours before the phot…

does anyone know why rockwool cubes turn green when they are wet and have been placed in light? my bet would be an algea or fungal growth but none the less, it looks bad and cannot be really that great for plants :thumbdown also, once its set in, is there any way to stop it growing or even better, kill it off? and if u keep the cubes out of light, will the green shit still appear ??? i have seen many clones with that kind of shitty looking cubes and dont want to take my cuttings and have that happen to them is all...

What can you tell about a plant from the smell of the buds? Every time I open my closet it smells like I've got some choc mint buds in there! I don't know if this is the organic fert I'm using , which smells a bit manure-ish, but it just made me wonder about what you can teel from smelling a plants buds ( citral , salty , chemically or what have you).

OK, I am using an EBB and Flow system, the nutrients are changed and the plants are washed every two weeks, the nutrients being used are GH (Grow, Bloom, Micro), the plants look great in Veg but once they are 2 – 3 weeks in Flower they begin to turn yellow (the tops first) with the veins staying green. The tips are pointed down with a little burn at the tip and once the leaf begins to die the tips turn up. The nutrient strength is as the manufacturer recommends (1200 – 1400 PPM / American System) the temp in the room is 70 or so and the water temp is the same. They feed for 15 min. every 4 hours only in the light period. I think it is an Iron or Magnesium deficiency…

Hi there...... Last October, i got some ducksfoot seeds............ I kept 4 seeds and gave 4 seeds to my friend............. His plants are doing well and are well over 6 ft but mine are very small, lucky if they are 3 ft............. I think it might have something to do with the soil ? This year for the 1st time i used different soil.................but its still a general potting mix soil.....i got the PH tested yesterday and its 7 which is neutral so im unsure what the problem could be any suggestions ? thanks JAS

Hey all, just wondering why my PH is rising so much everyday, from about 5.5 to 6.0-6.2 within 12hrs. I don't let it get higher than this, (it wants to) but i seem to be adding a lot of ph down to keep it under control. Did a flush and water change a few days ago. I could possibly be overwatering, timers 30min on/off because i've got some slight leaf curl on the higher leaves but this may be because of the PH. Any ideas? It's a hybrid aero/nft sytem with 2 seperate rezzys and both are rising. 1st week of flower. Thanks Grow Hard
