Hard to see under the grow lights. Try taking a picture with the grow lights off so we can see the leaves proper colour...

Why are some leaves curling strangely?
Hello everyone, the problems begin unfortunately. Why are some leaves curling strangely? I have not given any nourishment, the temperature and humidity are constant, will it be a problem of PH or EC? Thank you in advance.

Nutrient deficiency or surplus?
Hi Guys will post a pic shortly. Have to update the grow as we are actually heading into week 6. One of the white widows is a fair bit smaller than the other. And is showing some form of difficiency or nutrient burn. I think it may be due to to little phosphorus. Opinions?

Rusty Leaves
3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera. I also have slight "clawing" on many of the upper leaves. Mg/Ca lockout because of nitrogen toxicity possible? DoesnÂŽt seem to be fungi, as there are no spores to rub off.

How to fix yellow leaves, brown spots.
What should I do about these brown spots that are overtaking my leaves? There's also yellowing on the lower, older fan leaves.

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)
2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?

Tips curling up
I noticed the tips beginning to curl up. I did gave her bio grow in the last two weeks 0.5ml/lt ph 6.5 almost every watering i used bio grow. I have another 8 plants of different breeds and none of them showing anything wrong. I wander if its the nutrients or perhaps the light?

I probably have spider mites on my plant. Yesterday I sprayed it with Maag oil. Today I bought an organic product and sprayed it on the plant. Are the discolourations on the plant caused by the mites or burns due to increased light from the drops? Or a lack of nutrients?

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?
Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Curled leaves
Why my plant's leaves curl up like that? I think that there's an overwatering issue, but is there any way that my soil is not good?

I have canoe-shaped leaves in the 3rd week, just the lower leaves, I'm not fertilizing yet. I have LED light so it's not heat. I suspect something related to humidity or pH. Any experience?
