First Grow Issue

[not_sure]

Hi,

This is my first grow… in about 30 years. Specifics below:

Strain: WWA
Method: hydro - autopot (first time using this particular method)
medium: coco
Nutrients: General Hydroponics Flora
TDS: 900-1000
PH: 6
Temp: 74-79
RH: 60-70%
Light: HLG 300L V2 RSpec
Tent: 3x3 Secret Jardin Dark Room
Ventilation: AC Infinity 4"
Planted on 7/8 (germinated in 2 days!)
Flowering for roughly 2 weeks. They are roughly 3 ft tall

If you look at the below pics, the leaves have a mottled look of green and lime green color. I thought I was having a calcium deficiency… which I may have had but it looks like more is going on here. I do feel like things are improving but not as quickly as I would have liked. It happened after I refilled my autopot and went out of town for 4 days. When I returned a couple of the leaves had brown spots on them. I was a bit unrigorous when mixing my nutrients before I left. As a result, I threw away the water and remixed with much greater attention to detail. I also added GH CalMagic, Floralicious Plus, and liquic KoolBloom. My thought is that I got some micronutrient deficiency because of poor mixing practices perhaps due to some lockout. Please see the pics and any thoughts would be most appreciated.

Lower your pH to the 5.5-5.8 range and try to keep humidity under 60% as you progress into flower. They don’t look too bad honestly. If anything they are showing signs off nitrogen toxicity. May want to use something else for calmag. Since calimagic is 1% nitrogen.

Thanks @Budz . I am at the point in the feeding schedule to pull back on the FloraGro from 5.3 ml/gal to 2.8 ml/gal. I still have about 3 more days before that happens. Do you think it is fine if I wait the 3 or so days and then lower?

Less is usually more for cannabis honestly. Not always. I’ve never used your nutrient line. but there are plenty here who have.
