Week 6
These girls are flowering now and they are growing very vigorously. I added the scrog net today and did some defoliation/lollipopping to enhance the bud growth. This week I added some liquid seaweed to the reservoir to reduce stretch and to help the plants to make lots of bud sites.
Hi Shagrath !
I might be wrong but this looks like nitrogen deficiencies. At 5.5, maybe the pH is a litllelow for its assimilation ( I don't know antyhing about hydroponics so please forgive me If I wrote a "nonsense" ).
@TheBudWhisperer, I've added more PK and it did not help her but the buds are getting slighty bigger and today I gave Calcium nitrate as foliar feed to the sick one. Let's see if that helps 'cos those symptoms look alot like nitrogen def but it is weird at this point. Also I raised the light few cm and it is at mac height now and I removed 1h from daylight.
My best guess is not enough nutrients for that amount of light and some kind of deficiency wekened her more so she can't handle the lights at all, but this came to my mind just yesterday.
@Shagrath, nawe - ur using great white so not really diff. From hydroguard which should be fine at those temps. Not familiar with ur nute regimen but if the ml/l ratio is accurate then you could be right that they need a higher mix. 2.5ml/l seems a little light.
I’m only saying this because the other plants (on a look) are showing some slightly pale leaves so u could be right about a deficiency. Hard to say on this one dude - every hydro setup and nute regimen is slightly different and I’m sure you already know how finicky these systems can be and how quickly things can change. Best I got here but will be watching with interest👊
