ph 5.5, flood 5 times during light cycle ( 15 litre buckets), use half of reccomended nutes on back of canna vega bottle.

Hydroponic growing, unlike soil, means that you have to provide the plant with ALL necessary food in order to grow.
I went on the Canna site, and they didn't have the guarunteed analysis of hydro vega - so I am not sure exactly
what you are putting into your plants, but I know it's not enough... Your plant needs many different vitamins, minerals, and enzymes to thrive.

I would pick up some Cal / MG from Botanicare - and start researching complete nutrient programs to ensure that your plants get the nutrients they need.

If you would like some help - I would be happy working with you to put together a complete program - but I need to know things like - if you have a preference for a certain company, budget, goals - etc.

Looks like zinc, iron and mg deficiency coupled with heat stress

i keep my plants 10 inches from my 600 hps and ive never ever had a heat issue. the only time mine will burn is if i get the foliag wet then toss em under the light.

During veg it is best to have ph around 6.1, 5.8 is better for flowering, plants will absorb different nutes better at different PH's

I accept with information:Hydroponic growing, unlike soil, means that you have to provide the plant with ALL necessary food in order to grow.
