I've skipped to a day or two over 2 weeks since my last update. I'm today at beginning of week 16. The aphid issue was unexpected and a cause for more action and less chat and diary entries I guess.
So, week 16, almost the end of week 5 of flowering. I still get the very occasional small juvenile aphid and the cause of it, originally a single blackfly, is gone. I have had a few gnats too but they're OK, just a nuisance. A word to the grower who like me, is a noob: always change your clothing before you tend to your girls, just as general good practice but especially if - like me - you have been in your garden. There is EVERY reason to believe that you will carry something unwanted into your tent. I read about it before it happened to me. I ignored the advice and paid for it.
What did the aphids cost me. Well, initially and for the 1st week of finding them, I went through the plants daily, culling browth where infestation was high, removing leaves where less so, and spraying the remainder with a mix of isopropyl alcohol and water (40/60). I sprayed above my turbo fan and this carried the mist to the underside of the leaves. It was quick enough not to get evaporation of the alcohol. It worked for me, I brought down numbers by 90% on day one and I am fighting 1% daily. I is 99% better than it was but as I mentioned, I get the occasional beast. I was lucky. I was extremely lucky and caught it early-ish.
Moving on, nutes are up to max, White Shark has been added to the feed water every 3rd feed whilst the misting and spraying has been going on, likely only serving to make me feel better I guess, and CalMag added once a week in small amounts.
Never having grown from clones, and having removed 75% of the plants' growth due to conditions, lighting and ventilation and aphids, I am pleased with the development of the buds I have left! In fact, look at pic 1 - the SIZE of those trichs, right? There are no main colas, there are just lots of smaller buds developing at similar rates and starting to fill out nicely. I am going to hope to 80g dried but oh my, how much different the yield would and could have been with the (almost) perfect grow I could have made it.
I'll update again in about 7 days,and thanks for reading!!
