Yellow leaf tips

GrowKittystarted grow question 2y ago

I noticed strong yellow tips on one of the plants and wonder what it could be? I watered it 6 days ago 500ml with 1ml of BioBizz Biogrow. Other than that plants take water themselves with Blumat XL. Sprayed a bit epsom 4 days ago. Light: ~30-36CLI(17h) | Avg. Temp: 26°C, RH: 60%

The light is a little strong for vegging. The straight leaf tip burn is likely plant wanting more potassium. My plants around week 4 to 6 do this if I don't start introducing bloom booster a little. Vegging npk ratio is 3-1-2. A smaller dose of blooming nute with feed will stop it.

Looks like your light intensity is too much. Raise your light some or turn the dimmer down a bit

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.

I can not take out of the tent to the darkness more than 4 at once and wanna hear your suggestions before I go with yellow sugar leaves or some amberish :D I read something about harvesting immediately (not to crap the flower) when sugar leaves start to turn yellow and I have some! On the other hand, I saw some trusted videos that has some yellow sugar leaves. I want to ask you if you have any experience with this issue?

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same. I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…
