Haven't been posting because not much of interest has been going on... After the first few weeks, the grasshoppers turned out to be a non-issue-- we let the chickens out and they cleared the area of most of the LF's, and the heat and drought took care of the rest. A few managed to get into the greenhouse and cause some leaf damage, but nothing serious.
Various predictions about the height of finished Critical Widow that I read in the Spring turned out to be conservative. I've been battling to keep the main colas tied down to a manageable height-- the greenhouse top is just short of 6 feet above grade, and they just keep growing! My single Blueberry Kush is remaining fairly short (under 5 feet)
As a rule, I'll err on the side of too little nutes, but that hasn't worked out too well this time-- I was giving them almost nothing... The photos of leaves above are examples of what I've picked off the lower levels of each plant every week for the last month. (The grasshopper damage happened weeks before.) The pH is fine (between 6.5 and 7), and it looks like a nitrogen deficiency, which is understandable since I didn't add any (FF GrowBig) to the watering-can soup. I started adding some again (2tsp/gal) for a couple of weeks until the girls were blooming in earnest. I just started adding Tiger Bloom this week. I'd held off using it since The Rev thinks it's the devil, but I don't have anything to replace it with. Better the devil you know...
I use 1/2 or less of the recommended strength with all nutes, mixing them as directed by the mfgr., but then watering with a hose after application to the root zone. Each plant gets about a half-gallon of nute mix before I water. I feed every other day now, watering almost every day. The heat and really low humidity require it. The number of necrotic leaves seems to be going down...
So far, the BK bush seems to be putting out only flowering tops, but all 3 CW's are showing the beginnings of some serious colas.
I can hardly wait for the weather to cool down. Daytime temps have been in the 90's constantly with forest fires all around...
Since the graphic supplied by GrowDiaries seems to say I topped the CW plants in week 9, a correction is needed: They were topped in week four (and five, for #1). Understandable since there was no Diary in week 4...
