Tips are yellowing jus slightly at 31 days flowering should i worry?

I ve got a blue dream at day 31 of 55 to 60 day flowering period with one smaller dream clone in same bubbleponics tote...clone has no yellow tips and the one in full bloom does...the clone is roughly 3 weeks behind its mother but shouldnt i see nute burn if thats what it is in both plants...i ve only used general hydro nutes and aquashield because my temps ran high wanted to defend against the bad please any tips would be greatly appreciated came too far now to seee her look bad...thanks all

pictures?? also whats ur ppm?? ph?? is ur water RO??

good questions from above, I am running BD also, they are pigs and can handle alot. Pics are worth a million

yea sry thought had already posted them ...but figured it out my light needed raising had heat stress due to light being too close had only very browned the tips...i dnt have water tester ..i kno i kno ...but my ph stays 5.7 to 5.9 and i have followed GH grow nutrient schedule with aquashield

figure out the optimum light height can be tricky and the symptoms often appear to look like over watering or minor nute burn. All you can do is keep an eye on the ppm and the ph which stays at 5.7 to 5.9 your ok. I use a different brand then the aqua shield and I've never had to deviate from the amount listed.
