I have used the 707 in the past and got away w/ no nutes for a couple weeks. Once they kicked into gear i put them on a fairly organic feeding schedule. Thats up to each person but a general formula from any major co. plus some
calmag should do the trick. Sea kelp (AN) is the bomb during flower but i assume thats not news to many people. Molasses also will help supply natural bulk as well as feed any beneficial organisms you add to the soil.
I like the mix...very nice quality ...but the 707 doesnt supply much in the later stages of growth. My plantshave yellowed badly about 4wks in flwr. Any ideas....dont want to toxify soil...
I have always added N during weeks 3 and 4 of flower. It gives them the extra boost they need after they have their bud set. You shouldn't have a problem if you dont go crazy w/ it and are pro-active. In case you dont know, old N diff. leaves will not get better, but it will help future leaves from yellowing and dying. I expect a good portion of mine to die off later, like in the final week, due to good flushing and the fact the plant is finishing its life cycle. Just dont over do it early into flower and things should stack up nicely.
For now you can try any organic N fert. and you should be fine. You can always foliar feed which seems to help quicker than through the soil.:damnhippie:
