Indica is flowering and has brown leafs but my sativa looks ok

to start off I have have 2 plants I'm growing as mothers to clone and move to a offsite grow room. most of my equipment has been at the other place so i'm without my trusty ppm and PH meter. The shorter plants pic 1 and 3 is Holy Grail and that that pic 2 is lovely jack herer. The only problem i've had with the jack is that it's getting tall really fast but this Grail started shooting pistols out on the top cola about 4 days ago and now i can see signs of flowering on other nodes. the Holy Grail is also showing some unhappy leafs.

The facts:
I water them every 2 or 3 days with RO water and feed them once a week with turtle tank water (for the Nitrogen)
lights are 18hours on from 6am to midnight 4 2' T5s

now here is what i think triggered this problem: my co-grower came by to check on them and gave them advanced nutrients grow (1-1-6) thinking it was a veg nutrient.
the jack doesn't seem to care but I guess this put the other plant into flowering.

so my question is can I save this this plant by giving it the corrupt nutes and maybe topping off the cola? also this browning is that caused by the stress of suddenly flowering or maybe spraying/misting them too much?

You shouldnt of had to have used either of these two items much in my opinion so hardly trusty items yet.

Turtle water would be for someone who could already grow so really more of an advanced proceedure and somthing i wouldnt call simple for the new grower, who said turtle water is nitrogen anyway, probably a lot more funky than that, and did you mention RO water with out mentioning the lost cal/mag it dosent contain? Stick your ppm and pH meter in a glass of your tap water and get back to me with the readings.

What triggered the problems happened a lont time ago judging by them weird coloured stalks and stems, maybe he just tipped the balance, personally i dont think its that the jack dosent care just that its had enough and any more just dont matter really.

I wouldnt be feeding them in that size pot in soil anyway so as to adding ferts basically a big no from me, please say this was its first and only feed plus that soil looks so wet and solid, perlite would break that up lovely and watering every three days, i'll send you ten bucks if that soil dries in three days!

From lots of things but stress of flowering isnt really a valid exscuse.

Lots to learn and change and read up but intresting to see what you pH and ppm meter thinks of your tap water, could be worth adding half tap and half RO if its got a high ppm and redoing the grow with perlite and few other changes might just be an option for the future. Peace

uhh you should get some weed specialized fertilizer with micronutrients rather than turtle shit

Its a simple fix. Flush and feed with some thing like MOON DUST. These plants are resilient.

I had good luck with my first grow using my meter to balance ph after adding fertilizer and take proper maintenance of it. i trust it more than a colored strip that changes depending on your lighting.

I'm aware few if not no dissolved solids are in the RO water this is why I use the water from a 400liter tank occasionally.
To answer your "who said turtle water is nitrogen anyway" question This would have to be science. Feces, urine, as well as any uneaten food, are quickly broken down into either ionized or unionized ammonia. The ionized form, Ammonium (NH4), is present if the pH is below 7. The unionized form, Ammonia (NH3), is is present if the pH is 7 or above. During this stage Nitrosomonas bacteria oxidize the ammonia, thus eliminating it. The by-product of ammonia oxidation is nitrite. In the last stage of the cycle, Nitrobacter bacteria convert the nitrites into nitrates. As to the exact number I'll admit I don't know but hopefully I can figure out what the plants need from their health.

as to urgod's comment about using specialized fertilizer with micronutrients rather than turtle shit.
turtle shit seems much more organic and natural too me not that there are not good fertilizers out there or that i'm trying to do a "organic" grow but i see no problem with turtle shit as you called it.

The plants may have been fertilized twice but they are now being flushed. as for the soil looking wet I do have perlite mixed in with the soil though it doesn't seem it from the pictures because there's about 1/2" of straight potting soil on top because i wanted to cover the rockwool cube that became exposed.

always more to learn.
I hope to get my meter back tomorrow and take some readings along with topping the plant to help it get back to veg.

as for fertilizer I wanted to move away from the fox farm i used first grow and try to find a 3 part system i could finer tune

The flush it under way as for moon dust I'm always a little put off by something that says "as seen on TV" though I do feel I want something other than the advanced nutrients i have now.

All of the above is why you are having problems!

You said it, you dont know whats in that turtle water, your right that urine dose brakdown into nitrogen but faces breaks down into a lot more than nitrogen hence why i said it probably contains more funky stuff than that, simply quoting the nitogen cycle, allbeit a simplified version, dose not account for all the other elements in the water. Add it if you want but yet another variable some one with plant problems wants to mess around with.

Your plants look heavily calcium deficient, probably from the RO water you are using. Before you use RO water most of us check that our tap water is unsuitable for plants and when using RO water a cal/mag supplement is required and asked for by most fert companies.

I couldnt care what the pH of my soil water and ferts are, lime in my soil and good drainage through the use of perlite keep pH constantly buffered. Imagine never having to use a pH or ppm meter again, real time saver and somthing for you to work towards in the future. People buy a bag of pre pH'd soil and first thing they do is say i got a pH problem!

First and main problem is your starving the plant of calcium-

Calcium is the one on the left in the chart, the one with the brown spots and yellowing. Peace
