bbdangles started grow question 3 years ago
On my NLxBB there appears to be rust spots developing on both sets of the first true leaves, i've only fed nutrients once on Day 10 and that was at quarter strength.

Not sure if this is a sign of overwatering or if I need to start feeding with Cal-Mag more regularly.

hi there so you have three problems. first of all overwatering, you can see from the "puffy" space in between the veins of the leaf and the wrinkled leaves that you're overwatering , this will actually shock the plant a slow growth. this article tells you what's going on with the leaves : https://www.royalqueenseeds.com/blog-what-causes-curly-cannabis-leaves-and-how-to-cure-them-n923 here s a fool proof technique that will help you figure out when you need to water : https://www.youtube.com/watch?v=osaYCQ_V1WU Third, and this the easiest problem, the actual rust spots on the leaves : calcium deficit. Calcium has uptake by the roots at around 15% efficiency, and by the leaves at around 9°% efficiency. So simply use a foliar spray with a saturated solution of cal mag , spray until dripping wet several times a week and the plant should recover within 5 days and start to thrive. hope this helps ! :rocket:

Guess feeding is a sure way to have trouble. When feeding in coco and hydro an EC/PPM meter is a must. At this stage you should feed mainly 0.5 EC (250 PPM) worth of cal mag and raise 100 PPM weekly with veg nutes.
