First Grow – Dyna Gro? PH?

gr0wC0d3

Hi im attempting my first grow.
Doing it outdoors in a greenhouse using Fast & Vast auto flower (they pulled me in on the name :S ).

It has gone ok so far, 1 major spidermite problem but i exterminated them soon enough.
I made a big mistake early on, i used soil with some slow release nutes. I have had to re-pot & it went well (surprisingly).
I have humidity problems as my greenhouse is on grass (im praying i dont get budrot) but it shall be moved to concrete soon.
1 of my babies has just started budding & now im looking for some nutes.
Ive read alot & dyna-gro seems to be one of the best however ive just seen a schedule on their site & it includes mag-pro, pro-tekt & bloom for flowering. Is this really needed?
Will the bloom be good enough on its own?
(im on a very tight budget & cant afford to get all 3) otherwise any1 know of other good cheap bloom nutes?

For veg (if auto-flowers have veg, ive seen some argue they dont) i used baby bio which is 10.6 – 1.9 – 1.4

Also while im here what is a cheap & easy way to increase PH of water? my PH is way off (below 5.0), i check the water most times & its always between 6.5-7.5 i guess that soil really was bad & i guess if i dont fix it it will creep up on me.
My watering/feeding hasn’t been on a tight schedule, i try & water every 4 days but sometimes the soil is still wet & others they wilt before that. I have been sticking to water-water-water with nutes.

Finally can they handle high temps, recently we’ve had a mini heat wave & its been at least 30C in there, should i be worried about temps or will she still thrive?

I can help you with your dyna gro questions. First off. Dyna gro is not organic and is salt based. To use it you will need to do at least 3 flushes during a single grow. One at end of veg. One mid flower and a final flush. This will keep salt from building up in your medium , which causes lockout. Also recommend that you use the full schedule of their nutes in recommended doses. But it is easy to adjust rates up and down as your plants tell you what they like. One last thing When you flip to flower you will need to mix the grow and bloom formulas 1:1 instead of just using the bloom , to supply cannabis with the correct nutes. Dyna gro was designed for orchids which need more P during flower than cannabis. Theses tips will help you in good ways. I’ve grown some great smoke with dyna gro nutes. Imo they are the best value for nutes out there.

Lots of good threads on dyna gro nutes on the web. Best of luck.

Cheers for the reply,
yh i noticed high P i guess thats why the schedule i saw said use bloom, mag-pro & pro-tekt in flowering (nothing about grow)
http://www.dyna-gro.com/Website pdf Files/DG Hydroponic Feeding Chart.pdf
mag-pro = 2-15-4
pro-tekt = 0-0-3
bloom = 3-12-6
grow = 7-9-5
They are autoflower & flowering shouldn’t last more than 5 weeks (1 just hit flowering rest in veg)
Ive been using other nutes for veg which is 10.6-4.4-1.7
Grow would boost all but still boost more of P.
Would bloom & pro-tek be ok? as (from what ive read) they need less of N higher PK in flowering, the magpro (like the grow) boost them all but still more of P.

Flushing im still not 100%, as said i -water-water-water & nutes- would those 2 waterings count as a flush? I water until i get a fair bit outta the bottom before i stop filling her (or pause if it builds up on the top too much, poor drainage :/ ).
For big buds in flowering should i be adding nutes with every water then flush at the end? (I dont want chemically tasting buds & was planning to use only water for last week or 2).
Also would you still suggest mid-flower flush for less than 5 weeks of flowering?
