So help me pull the trigger on a change.
I am running a flood and drain perpetual grow using 2 4x4 tables under 600HPS bulbs.
I flower straight from clone every 2 weeks.
I use 5x5 pots with an inch of RW Mini cubes ("croutons") on the bottom and straight perlite on top.
I have been growing for about 2 1/2 years but I would totally call myself a new grower and my harvests have been disappointing for a lot of reasons.
Nutrients is the last thing about growing that I haven't educated myself on. Environmental Control, Lighting, Cloning are all now in pretty good shape.
Even the switch to an Al B Fuct style grow matches my personality and physical limitations much better than growing big plants under a 4x4 scrog in an RDWC
Things are starting to show some promise.
I have always struggled with various lockouts and deficiencies that have severely reduced yield. I have usually shrugged this off as a "pH Swing" or a fussy plant that doesn't tolerate high EC.
My choice of nutes was based on price and the recommendation of the grow store.
But it is time to get serious about my nutes.
I think I have been using the wrong nutes and way overfeeding them.
Usually EC in the range of 1900 - 2200 pH 5.6 - 6.1
I have been using Dutch Nutrient Formula Gro and Bloom and some Cal-Max

GROTEK CAL-MAX 2-0-0 (3% Ca, 1% Mg, 0.1% Fe)
Gro in the Veg room and Bloom in the Flowering.
The plants in my tables are at different weeks of flowering so I need a recipe that is not too weak or strong.
150L H20
500ml DNF Gro A/B
100ml Cal-Max
30ml pH down
250ml H202
Was a recipe I was using to give me my target numbers on a fresh rez.
I was up until a few weeks ago also using 15ml of DNF Bloom Fortifier
Nitrogen

For Best results use DNF Bloom Fortifier 0-50-30.
But discontinued after starting to read this thread
https://www.rollitup.org/nutrients/570037-so-you-noobs-hooked-cannabis.html a few weeks ago.
I have also just started to mix a weaker solution with a target EC of 1500-1700. That seems to be helping.
My veg room gives me fewer problems but I really need my moms to produce nice thick strong clones.
I veg my mums in a 4x3 table under 6 4' T5s
My veg room is still "under construction" but in a week or 2 I should be doubling that.
So in what way would a switch to Dyna Gro help my plants? What do I have too much of and too little?
It all looks good to me but will it change much? Because it is not easy to find in Ontario and I am not a fan of shipping across the border.
Thanks for the advice.
