Troubled seedlings Is this nutrient burn? Had what looked like a lack of nitrogen early on, lowest leaves were healthy then quickly went yellow and worked up. Now have fed nutes at 0.7EC (tap water left for 24hrs to 0.28EC) so fed under 0.5. Bio-grow 0.5ml/l bio-heaven 1ml calmag 0.25. Thanks

Yellowing leaves help please (newbie)Hi guys, had a calcium/ magnesium deficiency last week which I have treated with calmag this week However I’m concerned the plant is yellowing more. Is this still related to the same issue ? I understand the brown spots won’t be reversed but should the leaves still be yellowing?

Yellowing of top fan leaves What is causing yellowing of the top fan leaves? Started to happen to a plant that I broke by accident during LST. However around the same time I upped to 2ml/l and moved the light a little closer. My ph has also been high (fine now). No idea which one could be the culprit

Leaves losing "color"/turning yellow-ish. (autopot without nutes)I've been using autopot system wihtout nutrients, plants now went to bloom. Could the smallest of the bunch (NorthenLight left down corner) have some defiency? As others are not "complaining", at least yet. Should purchase nutes that work with my autopot, only biobizz left now.
