Will excessively aerating and circulation change the PH?
VegasRonstarted grow question 4y ago
I have a reservoir which holds my nutrients until they need to be used. Recently I had added in a pump for circulation in addition to my air stone. Since then my solution has been rising to over 7 within a few hours. I adjust back down and it goes back up again? What the heck?

Have you changed your water? Build up of old salts from chemicals can contaminate it and will make ph unstable. Good luck and happy growing 🌲🌲🌲👊

This literally happens in 3 hours. The plants do not touch this water untill it empties into the main reservoir, controller unit. So the plants have nothing to do with the problem.

Early flower? How to reverse?My plant is entering the 7th week today. Had no sun for a while (too much rain) but over the past 12 days she gets direct sunlight from 7 am to 7 pm (the sun rises at 5h30). At night I leave my regular lights on until 10 pm (1 meter away from bulb). Is this a pistil?

When to switch to flower?I have 4 plants under a mars hydro ts2000. They are about 5 weeks old. I was going to top all of them once and switch to flower in a week or two. Does this seem like it would be a good plan for a decent yield or should I veg longer? They are in 5 gallon pots but the soil settled.

Almost done? What do you guys think? How much longer should I let them go?Today marks day 80 since they sprouted and day 53 of flower. Thinking about chopping in a day or two and wanted to see what some of you guys thought. Will they thicken up more if I give them another week or two? Do the trichs look almost ready?

Watering close to harvestOn the last days of the plant, i mean, close to harvest.
How you guys water your plants? Same system only when the top is dry? or you guys let it dry more, or water more than per example 7 Liter of soil = 0.7 L of water ?
And its normal that sugar leafs fade de color?Week 11
