New grow started...HELP!

[thewhitelotus]

Background:
I started 2 seeds in Master Nursery Gardners Gold Organic potting mix: A blend of sphagnum peat moss, composted hen manure, shellfish, perlite and very old dark bark. It is also pH adjusted with lime as needed. They are currently vegging under (7) 27W CFLs 5000k. Lights are about 2" away, temps hovering around 78-80 with lights on. Have intake and exhaust with a oscilating fan circulating air. My starters are about 3-4 inches now about 2-3 weeks in and i just put them into 1 gal containers. I was feeding them 1/4tsp Maxibloom per gallon before transplanting into the new organic enriched soil with feed, feed, water schedule.

Questions: Do i need to start feeding them right away or will the nutrient rich organic soil hold them over for a few weeks? i did notice some burn on the ends of the leaves yesterday and today it seems to have crept up the leave a little(thinking its nute burn and not a deficiency given the soil/nutes).

Also, they seem to be growing rather slow (4th set of leaves on 3rd week). Should i just water with tap water (PH around 7) for a few days and see if it progesses?

I am planning on using the KISS method using Maxibloom and adding Protekt not only for silica, but also a PH up (My PH drops to around 4 with tap water and 1tsp/gal of maxibloom).

Any information would be greatly appreciated. cheers!

Also, i have a 250w HPS and was curious when i should throw the starters under that to veg, along with the supplemental CFLs!

Not sure what your temps are but if you're in a garage or other cold winter location and only holding high 60s at times in the cab then you'll have much slower vegging.

Welcome aboard!

Welcome to ICMAG whitelotus!

Nice soil mix, lighting and everything else! Temps sound great, your RH should be at about 60% at this point. Good thing you've added a bit of lime to buffer the ph up a bit. That dark bark would have made things too acidic.

One thing I would suggest is that you should not need to add any nutrients into the soil while they are in this very fragile seedling stage whatsoever. The plants are just establishing themselves at this stage and will not be able to handle any added nutes.

If you're growing up from seed and have transplanted them into that organic soil mix you listed above, they will be fine until harvest pretty much as far as nutes are concerned. That hen manure will tide them over for a good long while and you should only add maxibloom in flower to give the buds a boost.
