Is this a deficiency or burn?

KurtThePlantGurustarted grow question 1y ago

I have 2 new, 2 week old seedlings in my grow room and the bottom first set of leaves is yellowing at the tips to like half way up. Their not as green as the new growth.

Looking at your diaries, the biggest problem I see your relative humidity. Those little seedlings need around 65-70% RH at this stage of their life. Along with 250-300 PAR/PPFD and a proper watering schedule. Provide those three things and they should bounce back. Also maybe consider up potting those plants in the next week or so.

Yellow on leaves Day 13 leaves started to look yellow / dull on tips hasn't seemed to improve 2 days later, it is the auto soil premix I'm guessing the roots are getting close the soil and nutes kicking in or does this look like another issue?

Leaves' apex yellow/white First grow here. This is an auto strain 20/4. pH is on point, I'm using growing nutes once a week (I water around twice a week). Only the young leaves have this. What is the cause according to you guys ? Is it a serious problem ? Thank you all :)

Lockout during transition Just a random question. I'm growing in a tent using coco and perlite. How do y'all keep your plants from getting nute lockout when they go from veg to flower? I seem to have this problem with every grow, no matter what I try with them. Thanks for any tips. ✌️ 💚 🌱

Leaves changing colour What’s wrong with this plant? Put her in manure instead of soil, just read John innes and thought yeah that’s fine 😂 I’m thinking it’s holding water more than it should or else it’s a PH issue. Help please? How do I fix it or stop it getting worse?

Nitrogen toxicity mid-flower So I overfed during veg and now my plant has nitrogen toxicity. Besides making leaves super dark, crunchy, and yellow it has also made my buds pistils curl and brown way too early. I’ve been flushing often with water. Is she a lost cause or should I ride it out for 4 more weeks?

I don't have a PH meter, just some test strips. Can anyone recommend an inexpensive meter I can get in the UK? There's a bit of yellowing on some leaves (see my diary entry on week 8) Buds seem to be developing a bit slow Should I switch from 24 hr to 20/4 or 18/6 ?

Week 2, leaves yellow-ish mottling, pH too high?That's my guess for now. I was going to use Blumat Tropf hooked up to tap but house water seems too basic. Only way I can think of remedying is to hook Blumat Tropf up to reservoir and make sure the water in it is the appropriate pH. Will that be stable?
