Hi Guys, I recently put 15 clone under a 600w to veg...feeding them a week nutrient solution of Canna Veg 1ml/L, a 6 inch fan provided exaust with a rotating fan blowing a gentle breeze across them....the problem is than while most of the plants have begun to sprout up nicely a few are displaying curling leaves and look like they are going to die....any suggestion?....I thought this was maybe due to wind burn or nutrients but all the other clones are getting the same nutrients and they appear fine. any help would be great guys

Hey peoples, I need some advice - I've germed three little ones from seed, raised them under flouros until they were a week old and potted them in a seed raising soil mix plus coir in large pots. They're about three weeks old now and were looking great up until a couple of days ago. I've been feeding with Miracle Gro Seafeed 3 in 1 at 1/3 strength every third watering (watering every 2nd or 3rd day depending on how dry the soil is.) They've been hardening off outside in partial sunlight for two weeks, and were due to go out into the garden next week, but the bottom leaves have gone yellow and are starting to burn at the tips - I've been reading up, and it looks like nu…

I've got one girl that's about 2 1/2 months old in a pot outside, she's about 3' tall and seems to be going OK but lately I've noticed the leaves are turning yellow from the bottom up and the leaf stems are purplish. Is this an NPK problem? I thought the new potting mix should have been ok for a few months? Cheers

Tap water VS Puratap water I tested the ec of my tap water at about 850 and I was far more confused when I compared this with my puratap twin filtered water that tested at about 900. I thought that puratap filtered water would have read far less than straight tap water. I then compared this to a bottle of spring water that was about 100. I’m just wondering if any of you have any suggestions on what the f is going on. I was hoping that the Puratap water would have been better quality. At the least I would have thought the puratap water would have filtered out some dissolved solids. I wanted to increase my additives, but with the water so high it’s hard to fit everything i…

General Hydroponics I thought i could get away with using just the Flora bloom and Gro but when i read the application table on the bottles and then on their site the Micro is included in the mix. Can i get away with using just the Gro and Bloom? And if so what are the best amounts to use?

Gday all, my plants are about a month old and they were doing fine for awhile until the bottom little sprout leaves began to yellow as did the first set of leaves (you know the ones that are serrated like true leaves but aren't multi-fingered like true leaves), then the tips of the first set of true leaves began to yellow and even brown a little, now all but the newest growth are yellowing at the tips and curling upwards with some of the leaves sporting yellow spots around the middle of the leaf, the main stems of the plants are healthy green but the leaf stems to the affected leaves are a reddish/purple colour. Now I've looked through countless guides and diagnoses tutor…
