First Grow going well - Over Fert Fix question PLEASE HELP!

This is my first grow and I decided if i'm going to do this i'm going to do it right. I have a grow lab with a 400w HPS that also came with a MH conversion Bulb. The two lBigger plants (Both Kushberry) were put in Miracle Gro Organic potting mix before I knew it was bad. All of the small plants (3 white widows, 2 unknown, and 1 citral skunk) are all in fox farm organic. I use tap water left to sit for at least 24 hours which has a ph of 7.5. The run off PH is 6.8 which I beleive means my soil is around 6.5. All plants have been on 12/12 for 3 days now. The two kushberry vegged for 20 days and then I decided to force flowering because of height issues (both were over 12" already) During Veg I did use some Peruvian Seabird Guano at a diluted amount and the plants seemed to love that. I used only water for the 2 watering's before switching to 12/12 and then the day of flowering i used some Indonesian Bat guano (accidently at full strength) and some Sweet synthetic Carbohydrates. The deficiencies started when flowering began. I water every 3-4 days on the kushberry which are in 5 gal pots with good drainage (the bottom layer is pea pebbles) I now know the 5 gal is way to big for my space, but i didn't know that when i transplanted from the jiffy cups. My temp stays between 78 - 82 degrees, Humidity at around 55%. I have excellant ventilation and air circulation (fan) and cool air intake. I run an ozone generator when I'm not home in case of unexpected visitors (family with keys). There are no bugs (since I got rid of the fungus gnats - dang mg soil) I have narrowed my problem down to nute burn b/c of the MG time release soil. My question - is there a way to flush the mg organic soil or will this just release more of the time release nutes creating mor of a problem? should i let everything dry out for a week and then start with just water for awhile? Or should I just leave it alone b/c its only on some of the bigger, midlle and lower fan leaves? ( any help would be greatly appreciated. ty

also, the smaller plants vegged for 10 days and then were added to the 12/12. I wanted these to stay small just to get a small amount of some other strains to try. These have not shown sex yet (obviously b/c they are only 16 days old at this point) and the Citral sklunk is the only fem seed out of the small ones. I'm hoping there is only one or two females out of the others, or i will be in trouble for space and light. Oh btw, lights are about 2 feet away from my plants. **I included a pic of one of the widows, it has a small hole in one of the leaves. everything else is great with the plant. just a deformed leaf?

bump, please help

Its hard to tell from the low blurry pics. But from what I can tell it looks like either ozone damage or a ph issue. You dont get your water from the hot water tap do you? P.S. Double posting will not get help any faster. Just uses server space.

pH Fluctuation:
Both of these leaves in figure 6 and figure 7 are from the same plant. It could be over fertilization, but more likely it is due to the pH being off. Too high or too low a pH can lock up nutrients in the form of undisolvable salts and compounds, some of which are actually toxic to the plants. What then happens is the grower then tries to supplement the plants diet by adding more fertilizers, throwing off the pH even more and locking up even more nutrients. This type of problem is seen more often in soil mixes, where inconsistent mixing of the medium's components leads to "hot" spots.


Figure 6 (left) and Figure 7 (right)
Ozone Damage:
Ozone damage typically found near the generator. Although a rare problem, symptoms generally appear as a Mg deficiency, but the symptoms are localized to immediately around the generator.

I've already read all the FAQ's and research material on this. posting a question was my last resort. My other thread has actually been much more successful so double posting has worked better. Cutting and pasting things everybody has already read is a waste of space. And no, my water is from the cold only run for 30 seconds before filling.

Well I guess you have it all figured out then. Outta here............

bump bump bump

bump bump for this chump..... LOL

If you have a local hydro store, go score a ph kit. It should include up down and a tester. The tester is only good for confirming the other tester you have, but the ph up and ph down are needed. Even in soil 7.5 or higher is no good.

That aside, go to just water for a while and you should clear up your issues. There is also a product called floraclean, it would if needed flush your system of nutes. It and products like it, can be used on soil, but it was intended for hydro.

Have you tried this yet?
