Its just a small light and should have no effect. Especially if it is green. It has to be a strong light or sunlight leaking in to cause issues. Think of how bright it gets where there is a full moon. If your really concerned about it put a bit of tape over the light. Happy Growing.

She looks to me like she's got a nitrogen toxicity - further evidenced by the fact you say you detected a calcium deficiency... you've given her too much nitrogen which has caused a lockout so that she's not able to access the calcium she needs - wouldn't matter if you gave her a whole bottle of calmag, she couldn't get at it. Flush her out and when you feed again, make it only 1/2 strength and cut back on the nitrogen-heavy nutes even going forward. I'd even advocate for a slight increase in your pH to 6.0 to help with the absorbtion of calcium... that's a perfectly acceptable pH in coco... I just think you're really overfeeding her right now and she's trying to tell you she doesn't like it. Red stems are definitely a sign of high stress... flush her and go easy on her! Good luck

You want at least 5 days between transplant and flip to 12/12... how long you go is more about how large you need the plants to be. 3-4L per month of growing... so if you will be pushing 4 months, 15L is about right and 20L wouldn't hurt either... biggest difference is later on you might get an extra day between irrigations by comparison. the plant should at least double in size, so when roughly 2/3rds of L x W of intended garden size is reached, it should fill in well. can always prune a bit if it overgrows and is at risk of microbial issues from all the congestion.

Absolutely, just make sure the heat is controlled, Red and Blue light will be absorbed 80-90% in the first layers of leaves (top down), Green light is designed to penetrate deeper into the canopy and is responsible for the large that develops but without Red & Blue all you will get is lackluster popcorn nugs. The optimal ratio for photosynthesis is RBG 1:2:1 Green although required, it is required in small doses, too high concentrations of green in the "full spectrum" can have negative effects, if you add side supplemental lighting, add Blurple to prevent all the greens from meeting in the middle. growdiaries.com/diaries/156342-grow-journal-by-exbeginner/week/903097 Potatoe, potato

il ph serve a far assorbire le sostanze nutritive alla pianta quindi il flush finale lo puoi fare con qualunque ph la missione è togliere le sostanze nutritive alla pianta in cocco lo puoi fare in 20 minuti togliendo praticamente tutto il fertilizzante poi bastano 48 ore di riposo e si puo' raccogliere e ora ti spiego.. il cocco è un substrato inerte quindi senza fertilizzanti e se non ne aggiungi la pianta muore il terriccio è un substato con nutrimenti è attivo e puo' far crescere una pianta quasi senza aggiungere nulla quindi un terreno attivo con una fertilizzazione normale avra' sempre un carico,seppur minimo ,di nutrimenti un flush fatto bene in terra ha bisogno di 3 volte i litri del vaso 11litri =33litri di acqua per il flush e alla fine avrai comunque delle sostanze nutritive il cocco è piu semplice in un vaso con 11 litri dovrebbero bastare 11 litri di acqua anche perche il deflusso in cocco è maggiore io quando ho le piante belle cariche inizio 2 settimane prima a togliere l'azoto e piano piano diminuisco fino ad arrivare a zero poi vedo quanto è l'ec di run off e quando è allo stesso livelo dell acqua che uso aspetto 48 ore e raccolgo ultimamente ho letto che un flush non dovrebbe durare piu di 20 minuti perche poi le radici ne soffrirebbero questo non so se sia vero ma farlo non costa nulla

In general the last 2-3 weeks are considered ripening. During this period providing only PK for 10 days is recommended by many growers and manufacturers. The last few days are left for flushing with special components for dissolving the salts accumulated in the substrate. This is made to specially cause active nitrogen deficiency. It forces the plant to break down chlorophyll and use all stored nitrogen in the leaves. Still debatable, but it’s believed that result is the boost of sugar production. That’s why GHE for example advises using only Ripen with no other additives for the last weeks of flowering.
