lol... you are lucky!

I've never really had issues in that regard until recently.. but of course I've added a daily soil ph and fert check to my daily watering checking routine... precautions... lockout lockouts before they start

thats the one... prices fluctuate a bit on these items.. i got mine for 18... but honestly as grow tools go... bang for the buck... a steal at 10X the price... you cant beat keepin ur numbers balls for good growth... dnt believe me? check my thread :

got the meter in jan sometime... from there out you can visibly see the vigor difference! and one thing i will stress here... autos have such a short life span that if you look at it... count it like this:
lockouts take about 2-3 days to show up.... then if you're real snappy... you correct it the day you notice... but still 2-3 days for the plant to adjust again.. so you're lookin at 5 - 7 days of bad growth... stress.. stunting...
5 days of say.. 60 DTH for low ryder 2 variety = 8.33% of the plants total life span.... say that happens in the veg stage well thats 5/21 = 23.8% of veg time... same if its during flower time
7 days of say.. 60 DTH for low ryder 2 variety = 11.6% of the plants total life span.... say that happens in the veg stage well thats 7/21 = 33.3% of veg time... same if its during flower time
I'll compare with a photo for ya now...
say ak47... I believe thats about 50 days of flowering time plus minimum 30 days of veg time... typically youd want 60 ... so we'll say 60
so thats 110days
5 days of 110 = 4.5% 5 days of flower time or 5/50 = 10%
7 days of 110 = 6.4% 7 days of flower time or 7/50 = 14%
so now I'm sure you see the cumulative effect...
this is why maintaining ph, ec and all the right factors is so much more critical for autos... less overall time to fix the problem.... plus theres no option to veg a little longer if the error happens during veg phase... in fact, it will likely speed the flowering process on you due to the stress incurred.

I'm out of commentary for now... lol
