I personaly never water or flush with my 7.8 wellwater. 1/4 tsp phDown per gallon of water put's me at 6.8. To that, I add the nutrients. Too acidic or too alkaline can damage sensitive roots.

Consistent watering is more difficult with every jump in pot size.

When watering the larger containers, I find it especially important to use a slow-trickle type of watering. I add a quart, wait a minute. Add a quart, wait a minute. Keep doing this, till you get a slow trickle of runoff. I do this with every watering and every feeding.

With larger containers, you can get dry spots in the soil. Since I flush every month, I avoid that problem. (mostly, lol) Sometimes I'll have to gently 'squeeze' the pot after watering to destroy the 'rain channel' effect, where the water follows a set path to the botom of your drainage tray instead of absorbing into the medium. Don't crush your roots though.

Everything else looks ok to me. Old leaves are old news. How's the new growth looking?
Rusty Trichome Reviewed by Rusty Trichome on . Best Curled Leaf Tip Ever! Pic Check it out... two plants bad, other OK... based on what I have read on all the forums, I believe I have underwatering. I have low humidity in the Bloom-Room with a ton of air movement sucking the moisture out of the girls. (Ph going in is always 6.4, GH nutes at 1/2 strength, 400HPS/MH, Sunshine #4 soil, pics of NYCD and TW at 1 week in flower) The tips aren't so much burned as just full curled... some tips look more like heat burn. I read somewhere this can happen when the plant is too Rating: 5
