First time Coco coir. I neglected to check the pH ...
CannaKropsstarted grow question 4 years ago
First time Coco coir. I neglected to check the pH before planting, and I can't seem to get the pH down from 7 to 6. I have tried rinsing with several gallons of 5.5 pH, no help. What is safe to add while growing? Thanks!

With my experience with coco the runoff is never in the absolute correct zone. If your seeing high just keep feed/waterings at 5.5 for your veg cycle. Cheers

Done that myself occasionally. I kept flushing it with ph 5.5 and it took a while to get run off right. I check run off by collecting 15% and ignoring it or and then collect 5% and check that. I find that way I get a better idea of what the soil is. 1st lot of run off will have a different ph then the last bit.

Nitrogen Toxicity?Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Runoffs are significantly below inputs-Do I have a problem?Runoff continues to be a mystery. When watering I continue to get significantly less Ph and PPM (4.8 ph and 109 ppm) than my inputs (6.2 ph and 155 ppm) but the plant looks healthy. I have no idea what is going on or if its even a problem. Should I be worried and what can I do?

What deficiency is this ?What is happening to my plant right now ?
I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks.
Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil.
Started around 6th week

Autos reacting to All-Mix: Slight nitrogen overload?Pheno one showed very "leathery", weak, hanging leaves of dark green. Same time the fungus gnats had a run and the population doubled. After second LST also the stronger plant showed those signs on the younger upper leaves. Also curled down a little. Slight nitrogen toxicity?

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliageAt first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?
