Heres a nice easy feeding schedule with very few ingredients that can grow big plants...... all you will need is a good light soil mix,I've developed this with Plagron Light so that's what I would suggest, a reasonable water supply, mine is PH7.4 and EC 0.4 most tap water will be around this range and the nutrients.
Base nutrients are Advanced Nutrients Sensi Bloom A&B then for bloom AN Carboload and Overdrive. Two of the test subjects were grown simply with these ingredients but the third needed extra Calmag so that's advisable to have. The nutrients are PH perfect so no need to check or adjust PH, I don't even adjust the starting 10 days water or the final flush water,it goes in at 7.4.
