Since my last post I had 3 of 5 feminized WW sprout and moved to the tent. So now I have a total of 3 bag ladies and 3 WW's. The bag seeds are the oldest 3 plants.

Today I saw signs of stress on the 2 older ladies.

First thing I checked was the PH and it had jumped to 6.8 from a steady at 6.2. This was expected though because last night I added 3 new buckets of hydroton into the system.

So, I added 15ml of PH down. WOAH, big mistake. The pH shot down to high 4's. Luckily I had the capacity to add 20L of tap water to dilute it back to 5.8. Still, I don't think the curling up of leaves w/ drooping was pH related. Instead I think it was a 2-fold heat issue; heat and lights too close to the tops.

A slight heat issue was in part due to testing my new temp gauge that records high's & low's and not running the aux A/C to see how hot it'd get without it ... 91.2F. So, needless to say, I'll need the A/C on until the weather cools down even more.

I believe the overall stress culprit was the fact my lights were too low. I raised them a few inches so now they're about 20-24" above the tops.

However, I'm paranoid about the light nutes on the seedlings, so I flushed all 6 with tap water which added to the dilution of the pH down in the res (but added to the high pH of the medium). Tomorrow I'll flush more with pH'ed water.

I've got tons of pics to share coming right up
