Hi mate,
Your room parameters are 25°C and 40% RH, but the good range for humidity according VPD (Vapour Pressure Deficit) is : 75-85%, at this stage of growing.
I guess the plant are suffering of dry air, especially at this stage of veg.
Hope this helps

This not a deficiency. It’s the EC of the soil becoming to high certainty because you’re not watering enough and getting no drain from the bottom of the pot. NaCl is starting to build up in the soil.

Did anyone water them when you were away? they were suffering from heat apparently but there is also a salt build up in your pots. I can only guess that someone watered with inadequate amount of water,without runoff. If not, this message will self destruct.

Contest curiosityFor those who have experience in contests:
How do they work? I assumed that a 2 week timer that runs out would result in someone winning lol. Isn’t that why the timer is there or am I an idiot? I feel like it should be specified somewhere if not to prevent confusion for new pplOther. General questions

F44: dozens of gnats stucked on buds & sugar leavesHey,
I noticed dozens of gnats stucked on sugar leaves and buds trichomes/resin... I tried to pick them by hand but there are too many.
I saw articles about bud washing which seems to be a good thing except for higher mold risk.

Flushing with RO Water (EC 0,0) or tap water (EC 0,8)?Hi.
I think, it's 1,5-2 weeks before they are ready to harvest.
Tell me, if you see something else in the pics. :)
I want to flush them now every 2 days with only water.
I have the opportunity of RO Water (EC 0,0).
Should i use the RO water or normal tap water (EC 0,8)?Week 11
