Flowering day 33 brings an end to this week and the girls seem primed to fatten up! The root structure looks great and has become enormous. Some leaves discolored from pH fluctuations. The smell has become so strong, i have to resist the urge to leave the tent open too long because it will quickly fill the room.

I am still seeing a rise in pH immediately following a reservoir change. I am letting my mix sit for several hours before the change and it tests perfect at 5.8 before the test, the old mix tests good at 5.9 But over the next 12-24 hours it will rise to about 6.5, i adjust it and it stays good for the rest of the week. I am seeing some discoloring of the leaves from the pH swing but nothing too bad. I will continue to keep a close eye on it.

Grow Questions
Cultus week 1 started grow question 2 months ago
These girls are needing to be topped, but since i just put them into the dwc system should i wait untill the roots have reached down into the water? Or is the rootball in the rockwool good enough to go ahead and top them, so they can get on with recovering from the stress?

Hi @Cultus! In this scenario, I would act by priority, and give them a few days to build strong roots. When you top, you can remove as many nodes as you want, it's even better to wait for 1-2 nodes to develop above the topped node, plants will recover faster. If your goal was to top at node 3 [for example], you could do it now and take the risk of a long recovery time, or you can do it in a week, by removing a bigger part of the plant, but with a shorter recovery time and a strong root system. Hope this will help, keep us up-to-date and happy growing :facepunch:

Well i seem to be guilty of being TOO strict with mt pH.

I am continuing to get more brown spots on my leaves which i believe to be a calcium deficiency, but not because my nutrient solution is lacking, but rather i have been locking it out keeping the pH right at 5.8 and not letting it drift over 6 to get access to the calcium.

So from now on i will only make adjustments when it drifts outside of the 5.5 to 6.5 range and for now i adjusted it to 6.1 for a couple days till next rez change. Bud growth seems to have slowed a bit, so hopefully this will improve things and make my girls happy!
