Been using Biobizz up til now - just received PM nutes

Soil Bloom

Bloom Boost

Silicon

just watered batch 19 days old with 3mil PM Bloom and 0.5mil silicon - all good

batch day 52 tomorow - not sure what to give them?

PM schedule says 5 mil bloom at that age plus 1mil bloom boost

Im a bit scared! might try 4mil bloom + 1mil bloom boost ( not added any silicon so far - is it too late? )

anyone?

It is always a tricky one when swapping nutes halve way through. I personally would not recomend it, but if you're out and are likely to swap over anyway then needs must and all the rest of it.

Go on the side of caution. I know it is probably a bit late now, but the 19 days old one should in theory be ok to swap straight over, the older stuff though I would be careful, add the Bloom Boost @ the rate of 0.5ml per litre and only 4ml per litre on the Bloom feed. This is because your plant will have been used to getting a certain amount of NPK from you current nute and adapt to these, so going straight in with a synthetic fert may cause a bit of tip burning. Watch you plants, if they're hungry then up the dosages, if you see a bit of burning then back off a bit.
