Hi All,
I am approaching week 4 of my NFT grow. (first timer)
I decided to use H&G Aqua flakes.
From day one my ph has just kept skyrocketing was sitting at 7.1ph & EC 0.8. I would have it at 5.5, in a matter of 6 hours 7.1.
Using straight Tap water - ph from tap 7.3 EC 0.2 temp 15C
In the first week or few days should I say, I had to immediately tweak the setup. Remove reservoir from tent to lower reservoir temp, added chiller as temps in reservoir were hitting 24C. Temp stable 19-20C.
I think in the first week I also did about 3 water changes ranging from 50% to 100% changes. same same.
week two I purchased H&G stabil/osmose added it to tap water with 7.1ph and 0.2EC temp 15C.
that took my ph to 8.0 and just wanted to keep heading to that number even while lowering it to 5.4-5.5, within 12hours.
I've turned off all airstones, nup.
50 & 100% water changes, nup.
letting water sit for longer, nup.
week three I changed the filters and fired up my RO system. 4.8-5.1ph 0.0EC temp 15C, I wasn't sure whether I wanted to add the stabil/osmose but I did, ph 7.8 0.2EC temp 15C with heater. I lowered the ph to 5.5 and it sat stable until I added it to my system and started circulation, it took 24hrs but has been sitting at 7.6 and is now sitting at 7.9 and EC has been lowering gradually with it.
So after all that, ill provide pics but they're happy and healthy and growing, now whether I am getting optimal growth I doubt it but I have nothing to compare to as this is my first time with NFT.
Question: I have been reading a bit more on nutrients the last 48hrs. A fair bit of stuff doesn't seem easily accessible to us in Oz but I had planned on taking the plunge and placing an expensive order to potentially have our customs seize it. SOOOOO...... Advanced nutrients hahahaha jeez its like bringing up religion or politics at the dinner table, They state with their ph perfect nutrients that even when the ph is out of whack their solutions still make nutrients readily available to the plants. Pretty bold statement, but from what I read they're quite good with their statements. My question is, if this were to be true, is H&G doing a similar thing and I just haven't read about it? In all honesty I've been reading so much about other nutrients and just started reading more of what Ive got and they're meant to be pretty good, instead of changing I'm going to get the full line up for this grow and maybe next before giving something else a go. At the moment I have a starter kit, so im going to get majority of the others and do the pro nutrients instead of classic which leave out added nitrogen and mag etc.
I'll add some comparison pics, so you can see the plants from then to now and maybe someone can shed some light into what's going on here. While I'm happy they are doing well, they shouldn't be and I don't understand why and that makes me nervous, maybe they're not doing so well and someone has some tips.
TIA and happy growing
