First Grow Blue Cheese Auto

Hi. Once your tap root came out you then placed it 2cm below the surface and covered the seed with soil. You would have been best off then giving it a little spray then leave it in a dark warm place, the ground needs to be moist not damp or your seed will drown. I'm not a fan off starting them off under a hps light as I feel they dry out the soil to fast while germinate.

Look like a little heat/light stress by the way the leaves are curling up and look slightly bleached but hard to tell for sure with you light on in the picture. I would raise you light or lower the intensity for a week or so. Let her grow a little before full sun.....I hope this helps...Good luck

It could be heat stress. Doesn't look like a N problem. Also might be the roots have outgrown your pot.

Yes. Next time, fill your pots right up to the top, this will provide more room for roots and the more roots, the bigger the plant. Plus, the soil is the cheapest part of any grow, so why skimp on this vital ingredien?

Nitrogen/nutrient toxicity would be my diagnosis, as well as being exhausted. Each plant is a law unto itself, no two plants will ever require the exact same conditions/feeding/watering. Also, 24/0 is not what plants need, they need sleep/a dark period to complete their photosynthetic cycle and have a correctly functioning metabolism, but the good news is that it is never too late to switch to 18/6. Cannabis can only grow so much during any 24 hour period and this growth tops out at about the 18 hour mark, meaning running your lights any longer than 18 hours is basically a waste of electricity, therefore even 20/4 or 22/2 or 19/5 or 21/3 is also pointless. At this stage I would be giving just plain water for the next 10 days before resuming feeding with half strength nutrients. Trying to flush the soil with excessive amounts of water will just make things worse, as this will just release even more nutrient salts from the soil, increasing the nitrogen/nutrient toxicity effect.... possibly killing the plant. From the very green colour of your plants, I would guess you are possibly feeding them too often. In soil, you should be feeding every third irrigation, that is ..... plain water/plain water/ feed/plain water/plain water/feed, so that your plants are only getting nutrients every 10-14 days (roughly). Also when giving water, you must give enough until there is run off/water coming out of the bottom of the pots. This serves two purposes, firstly, that the substrate is moisten from top to bottom, which is vital for root growth and secondly, it helps to prevent the build up of nutrient salts in the substrate/soil to toxic levels, which seems to be what has happened with your plant. Also watering deeply and thoroughly every few days is much better than watering little amounts often, which just causes salts to build up. Waiting until the top 3-5cm have dried out again is when you know that it is time to water your plants again, deeply and to run off. I have found that half strength nutrients is usually plenty strong enough, especially when it comes to autos. Lifting the light while this plant recovers may also help in its quest to resume health. Hope this helps, Organoman.

Hey, there are few reasons why things go purple. Could be because of rooms temperatures, light stress or LST. Also some strains purple and get more coloured as time goes on. Their is one deficiency that can cause some purple blushing on stems and that's Phosphorous. given your feeding amounts I doubt it is that. In some of your pictures on your diary it looks as if the plants may have a bit of light stress, It comes out as mini yellow tips on the new growth. I don't think it is Nitrogen deficiency that also shows a yellow tips as the plants are so dark green, Maybe even to much nitrogen. Side note, If you can lower your temps a bit at night and during the day if possible. 24-26c is ideal and 28max. 31 all around is hot hot with only 25% RH. But if its all you can do with what you got it will be ok. its just fine tuning the numbers. This is a good little read of why things purple as well. Could be of some insight to your situation. https://www.royalqueenseeds.com/blog-should-you-worry-about-purple-or-red-cannabis-stems-n1311 Good Luck and Happy Growing!

I think you need a nice all around feed. If that bloom formula you are feeding doesn’t have a good source of Nitrogen - I’d find one. You don’t wanna go overboard but I’d feed a nice even feed like 1:1:1 or 1:1:2. You still have some time left on this so a boost of nitrogen won’t be a big deal. My bet is you switched to a flowering formula too quick. You still need nitrogen at good amounts thru first couple weeks of flower, and still small doses after that. Good luck

Agreed with Roberts on this one.
