To feed or not to feed?

OK so heres the deal, plants are in week 4 flowering under 400whps lots of beautiful white hairs everywhere.... well you know how plants look after 4 weeks. They look very healthy with an abundance of green foliage,

I fed with teas early on but the soil seemed rich and slight burn was showing so went back to plain water, have been watering with just water for 6 weeks now and plants look mega healthy just from amendments.

Just wondering if it would help bud production by adding bat guano at this stage ( 2-15-1) as a tea?

I dont want to over do it but am obviously aiming for a good yield. Will the bat guano tea help or hinder?

Use half to a tablespoon per gallon, I wouldn't exceed that if you were to use it now. You can always add a little more later.

so true, always easier to add than take away. Erring on the side of caution ill probably go with the half tbsp per gallon and build up. Thanks

Half would defenitly be a good considerable amount. Say you are in 4 weeks of flowering. So lets say you have 5 weeks left to be on the safe side of things. Adding this would not hurt. Stay at half anyway all the nutrients in the soil and the plant leaves are about to be used and converted any way. So go for it. Feed all the way through and wait for your flush cycle right before harvest to stop

Ok so a little update, just looked in today and it appears the lower leaves have already started yellowing a bit hmmm me thinks they need feeding. This is especially visable on the lower sativa leaves... The indicas seem to be doing ok really. Good job ive got a tea brewing

If they appear to need nitrogen, it would be best to add a guano with more N. If you have a high-N guano you could use equal parts of that to the high-P guano.
