Nutrient switching...eeek - is this gonna be ok???

Hi guys -

Got a few concerns and looking for some advice... please!

Went into flowering 11/30, have 4-10 weeks left depending on strains. We're 1st time growers and have 4 different strains NL, HB, CS & TW. Growing in Humboldt 707 coco, using Grow-pots (material like), vegged 5 wks. under T5 216w and 2-26w cfl's, and flowering under 1000w hps.

We got a bunch of products/nutes from a workshop and due to short finances went with the *free* Ubiogrow (we got 8 bottles of it). We have enough left for 1 more watering then need more. We've heard a lot of positive feedback about the Fox Farm line and want to go with that product from here out. Is this a big issue to change mid-stream?

Here's some pics taken today, they are 4 wks flowering as of tomorrow. Let me know what you think of our grow so far and thanks so much for all comments and advice. Suite & family

is there nobody out there who can help me with this?? I have looked through the forums and not seeing an answer..

While it's lovely photography, the pics don't show the plants very well. Try to take pics under normal lighting and always include whole-plant pics. Where problems occur is info important for diagnosis.

No. Changing fertilizers alone won't cause any problems. There are situations where changing ferts affects pH or moves nutrient ratios out of whack, but all of that is avoidable.

From talking to people here about their fertilizers, Fox Farms seems to be one of the better premixed ferts. We haven't used it ourselves as we mix our own fertilizers fresh.
