Hey buddy, just caught my eye you're using Sunshine #4. Imo, it holds waaay too much water. Be wary of over-watering! I switched to Rainforest blend because it drains so well...
I've heard a million things about soil grows lol but this is what works for me. I fertilize every other day with half-strength nutrients, and give plain water the other days. I flush before transition (less stretch) and before taking cuttings. I use water only the last 10 days or so. Never have problems with nute burn, root rot, or soil chemistry if you are consistent and err on the side of 'less' when it comes to nutes.
If you're using RO water, don't worry about checking pH (IMOO!) because the nutrients are pH balanced and as soon as you add them the water takes on their value. If using tap water you will need pH down. I use tap water and pH my nutrient solution to 5.8. I wouldn't worry about TDS or EC at all.
p.s. use 5 gallon pots!
kest30 Reviewed by kest30 on . Hydro question on feeding Have used FF soil in the past. Going to use Sunshine mix #4. I will be in veg and flower in 3 gallon pots. Growing 6 Liberty Haze under 1000w. I am totally unfamiar with where to go from there. I know that I should first use Calmag in the RO water. I will be using Foxfarms grow big for veg and big bloom for flower along with Tiger bloom. What kind of feeding schedule should I have? When using a soil less mix I would assume I need to fertilize every day when I water them. What would that look Rating: 5
