I suspect I might have put too much dolomite lime when reconditioning my coir and now get high pH reading in my run-off. Could it be responsible for yellowing top colas? It's the 3rd time using this coir and 1st time using dolomite lime. I water at 5.8 and it comes out at 6.8. Anyone seen this before, can I fix it? They are at week 5 of 12-12.100_3273.JPG 100_3274.JPG 100_3275.JPG 100_3276.JPG

I never use dolomite in my coco, even after multiple uses. I use a coco specific nutrient. House and garden cocos a&b, plus their full line of additive. The cocos a&c has extra cal mag to compensate for the lack there of.

I'm too doing my first run in coco , like you I'm also using house & garden cocos a&b

And I only use cmx by Fairform it's sorta like calmag I guess

However I'm running 2x 53litre drain to waste buckets in a 1x1x2 m tent

4+ week vege

And I'm waiting on a scrog net in the mail

Started at 20 - 4 light dark period but over the last week I'v backed it back to 16-8 , I'm just hoping the screen comes this week because I don't think I have the room for more vege without limiting flowering room

May have made the canopy to thick

Yeah I hate it when that happens, plants start getting too big for space, I do that shit pretty much every run in some capacity.
Sounds like a killer little setup with the 42 liter pots. I love coco as much as my hydro setup. After going coco I never went back to soil. Phenomenal results.
Good luck on your grow bro

Why are u putting d lime in recycled coir? Dolomitic lime is a pH adjuster meant for long term crops in acidic soilless mediums like peat moss. Lime is too slow releasing to really get the benefits of its calcium and magnesium properties for such short term crops like cannabis. Especially indoors.
