Hi all!
First, here is 2 photos of my not-so-sexy ladies.
The details:
800 watt cab
10 square feet
Grape Krush
DWC
5th week in veg
70% of suggested nute dosage
66% of Cal-mag suggested dose
Is this a magnesium deficiency again? The spots don't look like the same rust colour they've had in the past. I had that problem in my first grow as I didn't know RO water needed cal-mag added to it. I bought some cal-mag and they immediately turned around.
Two factors that could be influencing their condition;
1. I'm only changing the res every two weeks, as opposed to one week as in the past. I've been topping with water but no nutes. Is 2 weeks a mistake? Is not topping up with nutes a mistake?
2. The ph has been rising pretty quickly. I adjust it once a day but it is consistently 6.2-6.4 before I get a chance to add more 85% phosphoric acid.
Thank you! Thank you! Thank you! RIU, you saved my first crop when I had some bumps in the road and I am grateful. Please help with my second. I promise to give back to this sub-forum once I have the confidence to give advice.
