Good Morning All

Today my little lady is on Day 30 and was just fed 2 grams of MegaCrop

She appears to be doing well.

Good Morning w

Today is Day 39 and is still being fed 2 grams of MegaCrop every 3 days. Next batch I will up the feed to 2.5-3.0 grams of MegaCrop per gallon and may add bud explosion @Bill.de.Cat @Dankerson @Don't Fear the Reefer @TrichomeAssassin @Trichome farmer

Beautiful pistils.

Thanks @TrichomeAssassin some yellowing oh leaves so hopefully next increased feed with fix that

Good Morning All!

Today my little solo is on Day 54 and still being fed 3 grams of MegaCrop and May increase next week. She’s being fertigated every 3 days in soil. I have some yellowing on the leaves and thinking she needs more nitrogen.

I’ll let the experts decide

You guys think I need to up the nutes from 3 grams to 4 of MegaCrop?

I haven't used MC so I couldn't say for sure, although based on the photos it looks a bit hungry. I'd try it out and wait 3-4 days to see if it improves.

Nope, I see tip burn, and the pale leaves go top to bottom, so I don't think low nutes is your issue, I think lockout by excess salt buildup or ph is more likely. If I were you, I would carefully check the EC/PPM of your runoff and adjust accordingly.

On my solo grows this round I have noticed odd pH behaviour that I think is specific to solos. Late in the grow, every one of my solos goes higher in pH, in the last measurement one of them had runoff over 7.0, which is out of bounds and then some with coco. The strange thing is that every one of my large pots on the same reservoir go acid, one to less than 5.0 today. The solos, at least late in the grow, have the opposite pH trend in the medium that my large pots do, even on identical nutrients. I have had to take the two solos still in the drobe off the res and fertigate them manually with lower pH nutes.

Anyway, I suggest that you have lockout, and, unless you have or want to buy a pH meter for soil, the easiest way to check that is check your runoff. Most growers do not fight runoff pH, but I disagree. Runoff pH is a reflection of conditions in the medium. If I start with 6.5pH input and drainage in in the high 4's, the medium is likely significantly lower pH yet, which is bad news. At pH's well lower than 5, stuff gets locked out. It is true that getting runoff back in pH range is a pain, but I do what I can anyway. Earlier today, I flushed the 4.9pH girl with about a gallon and a half of pH 6.5pH/`1200EC. I have now done this several times with the two largest plants. The larger girls seem to develop the pH issue earlier due to their larger drinking appetites.

In this grow, my nutes for the solos are now delivered at 5.5, and for big pots 6.5, and I have flushed both vigorously to try to get the pH in the runoff back somewhere between 5.5 and 6.5. Keep in mind here that the difference between 5.5 and 6.5 is a ten fold difference in acidity, not ~20%. Ph is a logarithmic scale.

I have also increased fertigation to 45 seconds every 3 hours. The longer fertigation seems to keep most of the large pots in bounds, but not the solos. I don't have a separate res and pump for the solos, but I will if I do them again next grow. Even if EC can be managed ok by adjusting nute delivery, it seems that pH behaviour late in a grow means a separate reservoir would be better.

I hope some of this blather is helpful, good luck with it.

Good Morning All

Today my little Girl Scout Cookies is on Day 72. I stopped feeding her today and will probably chop this weekend!

What do all or any of you think? @Bill.de.Cat @Dankerson @Olderfart @Don't Fear the Reefer @Trichome farmer @TrichomeAssassin
