But as others have pointed out, some growers need a lot of feeding guidance before they learn the fine points.
I think it would be a great service to have a default feeding schedule that reflects reality.
Not being funny my post is just that!
Edit : this is more definitive and how I do it.... although I use also meta boost to tweak EC to the stated levels below. A+B can be used otherwise.
For coco :
The key is knowing where you start.
Me... I use RO water so base EC is 0.
For preloading / feeding seedlings days 1 - 7 I aim for a total feed of 0.3 EC. So from 0 EC base I first add liquid silicon. This is less soluble - so add first and shake well. It will not move EC.
Next cal/mag. I add to raise EC 0.15 for first seven days. Then up to 0.3 for veg and 0.4 in flower. If I see cal/mag deficiency .. add 1ml / 5lt.
Next is A+B.
Basically, first week do not go above 0.3 total with cal/mag. 0.20ml/lt. Then up 1ml/5lt each week till clawing on new growth. Less is more. In veg 0.60.0.7 is good. You want light green not dark leaves... easy to add - pain in the ars to remove.
Then full flower, still at 0.6/7 start to add PK. Again up 0.1 EC per week till tip burn.. push them baby!
Clawing is not praying - so you need to be able to read your ladies. If in doubt read the green of the new leaves ... lighter and healthy is better!
I also add rhizome cana at 1ml/lt till two weeks befote flush. Cheap, builds roots and does not move EC.
Always pH the above once rested.
IME Meph girls are sensitive to nutes... feed correctly at the right stages !!!
Simples ;-)
